2 December EXECUTIVE SUMMARY Golder Associates Ltd. (Golder) is pleased to present this report, which outlines the initial stages in the development of a Groundwater Protection Plan (GWPP) for the three water supply wells currently owned by the Village of Midway. It is understood that two of the Village wells (Well No. I and 2) are currently used to supply domestic water to Village residents, while the third well (Well No.3) is not currently in use, but is being considered for use as a backup domestic water supply well. During the course of the development of this GWPP, it was discovered that the Village has a fourth well (Well No.4), which has been out of operation for an undetermined amount of time. It is understood that prior to the drilling of Well No.1 and upgrading the Village water supply system in 1995, the majority of water supply in the Village was provided by privately owned wells and Wells No.2 and 3 were only used to supply a small portion of the community. The majority of homeowners in Midway have connected to the Village water system for domestic water supply; however Village records indicate the presence of 32 private wells it is understood that at least six private irrigation wells are still in use within the Village boundaries. The objective of the first phase in the development of the GWPP is to assess the short term (250-day) time-of-travel zone for each of the Village wells and to complete a preliminary contaminant inventory within these time-of-travel capture zones. Results of the hydrogeological assessment indicated the aquifer in the area of Midway (Aquifer No. 478) is a sand and gravel aquifer, which ranges from unconfined in the vicinity of Wells 2 and 3, to semi-confined in the vicinity of the Village Well No.1. The estimated aquifer thickness is approximately 20 m. It is inferred that groundwater flow in the area of the Village is from the upland areas in the north towards the Kettle River in the south, with a southeasterly component of flow as a result of the southerly/southeasterly flowing Kettle River. It is also expected that another component of groundwater flow is present in the area of the Village and is controlled by water levels in the Kettle River. Due to the uncertainty in the groundwater flow direction, the presence of the Kettle River, which may act as a positive boundary condition, and due to the large range in hydraulic conductivity estimates for the aquifer, it was determined that the analytical method of capture zone analysis was not appropriate and as such, the CFR method was utilized to estimate the extent of a 250-day time-of-travel zones for Village Wells No.1, 2 and 3. Golder Associates

3 December The 250-day CFR time-of-travel capture zone for Well No. 1 has a radius of approximately 130 m, while that of Well No.2 has a radius of approximately 70 m. Based on a theoretical pumping rate of 17.2 Lis, the 250-day time-of-travel capture zone for Well No.3 would have a radius of approximately 150 m. Based on the results of the contaminant inventory review it was noted that the majority of the area around Midway contains residential, agricultural and undeveloped land. In general, land uses of concern identified within the 250-day time-of-travel capture zones of the active Village Wells, No.1 and 2, consisted of active and potentially abandoned wells, and agricultural, recreational and residential land uses. Land uses of concern identified within the 250-day time-of-travel capture zone of the inactive Village Well, No.3, consisted of residential and agricultural land, transportation corridors (Highway #3 and the former CPR line). Items of concern noted during the well head assessments consisted of the usage of a dust suppression agent immediately adjacent to the well house of Well No.2 and the storage of a pail of an unconfirmed substance in the well house and the presence of a black, tarry substance spilled on the floor in one area of the well house of Well No.3. In addition, a preliminary GWUDI (Groundwater Under the Direct Influence of surface water) assessment was conducted for the Village Wells. Results indicated that the well completion details for the three wells do not meet the BC GWPR (i.e. the presence of a surface seal), and as such the preliminary GWUDI assessment would indicate that the wells could potentially be considered GWUDI. Although additional investigations would be required to confirm GWUDI status for these wells, this could imply that potential treatment (filtration or chlorination) of the water may be required by the Health Authority. The following recommendations are made with regards to continuing the GWPP process for the Village: 1. Presentation of Results It is recommended that the results of the initial phases in the development of a Groundwater Protection Plan be presented to Village council members and the Community Planning Team to receive their input regarding the direction of the plan. 2. Confirmation of Static Water Levels, Groundwater Flow Direction and Gradient and Refinement of Time-of-Travel Capture Zones As the direction of groundwater flow within Aquifer No. 478 could not be confirmed due to the limitations in water level data (water levels collected at different times of the year and poor spatial data), as well as a lack of River elevations, it is recommended that static Golder Associates

4 December water levels within the aquifer be confirmed. This would include the verification of wellhead elevations, static water levels within the Village wells and nearby private wells, and surface water river elevations. Once groundwater levels, river elevations and hydraulic gradients have been confirmed, the time-of-travel capture zones should be refined. For this purpose, consideration could be given to using either the analytical methodology, or a numerical groundwater model. 3. Confirmation of Water Balance Due to the uncertainty in the water balance for the Midway area, particularly the groundwater extraction rates from the aquifer, it is recommended that the Village attempt to obtain total annual extraction and pumping information from other groundwater users in the Village, namely the private irrigation well owners and the High School. Once the groundwater extraction data is obtained, refinements to the water balance can be provided. 4. GWUDI Assessment Preliminary information indicates that the Village wells can potentially be flagged as GWUDI, mainly due to the lack of a surface seal around the well. As such, it is recommended that the Village consider installing a surface seal around each well, and conduct other works to bring the wells into compliance with the BC Groundwater Protection Regulations (i.e., ensure that all caps are securely placed, place Well ID Plates on wells, etc.). Following confirmation of the groundwater flow direction and gradient, the GWUDI status of the wells may be assessed, taking into consideration the refined time-of-travel capture zones. 5. Completion of Steps 4, 5 and 6 of the WPT The completion of subsequent Steps 4 (Develop Management Strategies), Steps 5 (Develop Contingency Plans) and 6 (Monitor Results and On-going Evaluation of the Plan), as outlined in the Well Protection Toolkit, should be completed as Phase II of the development of a GWPP. As part of these steps consideration may be given to the following: designating groundwater protection areas, developing groundwater protection measures, decommissioning abandoned wells and implementing groundwater protection measures at the well heads.

8 December INTRODUCTION Golder Associates Ltd. (Golder) is pleased to present this report, which outlines the initial stages in the development of a Groundwater Protection Plan (GWPP) for the three water supply wells currently owned by the Village of Midway (or the Village), located within the southern interior of BC, approximately 25 km west of Grand Forks, BC (Figure 1) and approximately 1 kin north of the CanadalUnited States Border. It is understood that two of the Village wells (Well No.1 and 2) are currently used to supply domestic water to Village residents, while the third well (Well No.3) is not currently in use, but is being considered for use as a backup domestic water supply well. In addition, during the course of the development of this GWPP, it was discovered that the Village has a fourth well that they were unaware of (Well No.4), which has been out of operation for an undetermined amount of time. Based on conversations with Mr. Jim Madder of the Village, it is understood that this GWPP will focus on Wells No.1, 2 and 3, with some preliminary recommendations provided regarding Well No.4. Recent initiatives from the Interior Health Authority (IHA) require that groundwater protection planning be undertaken as a condition of the water distributor's operating permit. The current work was completed at the request of the Village of Midway to meet this requirement. It is our understanding that the GWPP is being developed with the assistance of provincial infrastructure grant money through the Local Government Grants Program. The completion of Steps 1-3 of the BC Ministry of Environment's (MOE's) Well Head Protection Toolkit, as outlined in the Methodology section of this report, will provide the information required to develop the initial phases of a GWPP for the Village of Midway. The Terms of Reference for this Study are outlined in Golder's workplan submitted to the Village on September 28, 2007 entitled "Workplan and Cost Estimate - Groundwater Protection Planning, Village of Midway, BC" (Proposal No. P ). Written authorization to proceed with the Study was received from Mr. Jim Madder of the Village of Midway on May 21, BACKGROUND The Village of Midway currently owns four water wells, two of which (Wells No.1 and No.2) are currently in use, one of which was formerly used as an irrigation well but is not currently being used (Well No.3), and one abandoned well (Well No.4) which is apparently located in the vicinity of the Village office (Figure 2). Information regarding the Village wells was collected from the following sources: interviews with the Village of Midway Administrator, Mr. Jim Madder and Public Works Golder Associates

9 December Foreman, Mr. John Boltz: a search of the MOE Wells database: and reports completed by other consultants that were provided to Golder by the Village of Midway. It is understood that prior to 1995, the majority of water supply in the Village was provided by privately owned wells and Wells No.2 and 3 were only used to supply a small portion of the community. It is understood that Well No.2, located on the closed portion of Dawson Street, midway between 6 th Avenue and i h Avenue, was formerly known as Well B, and that Well No.3, located on the north side of the CPR right-of-way near the intersection of 12 th Avenue and Beamish Street, was formerly known as Well A. These two wells were tested by Kala Groundwater Consulting Ltd. (Kala) in 1995 (1995a). Following well testing, Kala completed the construction and testing of a production well, designated as Well No.1, located near the intersection of Jesalin Street and 6 th Avenue, immediately to the east of the High School. The Village Well locations are provided on Figure 2. Construction of Well No.1 was part of a large-scale upgrade of the Village water system, which also included upgrades to Well No. 2 and the construction ofa water reservoir for the Village. It is understood that since the upgrading of the water system, the majority of homeowners in Midway have connected to the Village water system for domestic water supply, but that a number of private domestic water supply wells and private irrigation wells exist. Based on information provided by Village of Midway staff, 32 private wells are known to exist within the Village. It is not known how many of these wells are in use; however, it is understood that at least six private irrigation wells are still in use within the Village boundaries. The approximate locations of these irrigation wells, as provided by Village of Midway staff, are identified on Figure 2. The objective of the first phase in the development of the GWPP is to assess the short term (250-day) time-of-travel zone for each of the Village wells and to complete a preliminary contaminant inventory within these time-of-travel capture zones. This information will help with the effective management and protection of the groundwater resource. 3.0 METHODOLOGY 3.1 Well Protection Toolkit The Well Protection Toolkit (WPT) was used as a guide in the development of the Village of Midway GWPP. The WPT was developed jointly by Ministry of Environment and the Ministry of Health in 2000, and consists of a six-step process to assist communities that utilize groundwater to better manage and protect their drinking water sources. Golder Associates

10 December The six steps outlined in the WPT are as follows: Step 1. Step 2. Step 3. Step 4. Step 5. Step 6. Form a Community Planning Team; Define the Well Protection Areas; Identify Potential Contaminants; Develop Management Strategies; Develop Contingency Plans; and Monitor Results and On-going Evaluation of the Plan. For this study, the basic components of the first three steps (Steps 1 to 3) of the WPT were followed. However, based on Golder's experience with developing GWPPs, it was determined that the best approach for the development of the Village of Midway GWPP was to complete the technical aspects of the study before forming a Community Planning Team and initiating public involvement in the GWPP. With this in mind, the initial emphasis of the study was on defining the 250-day time-of-travel capture zones for the Village Wells and identifying potential threats to the groundwater resource from surrounding land use. Once the technical information presented in this report is reviewed and finalized, it can be presented to the public for review and input. The following provides the specific scope of work for this initial phase of the GWPP: Gather and review available information on the Village wells and local aquifer; Complete a Site Reconnaissance and wellhead assessments of the Village Wells to determine the level of compliance of the wells with the current BC Groundwater Protection Regulation (GWPR) and to collect static water levels of the wells to estimate a groundwater flow direction and hydraulic gradient, Identify aquifer characteristics in the area and estimate the extent of the shortterm time-of-travel capture zones for the Village Wells by incorporating available information regarding the groundwater flow direction and hydraulic gradient, Complete a preliminary contaminant inventory for the Village Wells, which includes reviewing available information (land use maps and zoning bylaws), completing a search of the MOE Contaminated Sites Registry Database, conducting interviews with representatives of relevant government agencies and conducting a windshield survey of the area, Prepare a report summarizing the study, and Present the findings ofthe report to the Community Planning Team and Village of Midway council. Golder Associates

11 December It is understood that further progress in the development of the Village of Midway GWPP (the completion of Steps 4, 5 and 6) will be based on the findings of this report and will be a function of funding availability. Issues related to existing water quality monitoring were beyond the work scope for this initial stage of GWPP and should be addressed in future stages of this initiative (i.e. Step 6). It should also be noted that in March 2005, the Ministry of Health Services and the MOE completed a draft version of the Comprehensive Drinking Water Source to Tap Assessment Guideline ("Source to Tap Guideline"). The guideline provides a structured approach to evaluate risks to drinking water in the entire drinking water system. The guideline is also structured so as to satisfy the requirements of any drinking water assessments which may be ordered by a Drinking Water Officer under the British Columbia Drinking Water Protection Act. The guideline is a flexible methodology for evaluating drinking water risks which consists of the following eight modules: Module 1. Delineate and characterize drinking water source(s) Module 2. Conduct contaminant source inventory Module 3. Assess water system components Module 4. Evaluate water system management, operation, and maintenance practices Module 5. Audit finished water quality and quantity Module 6. Review financial capacity and governance ofthe water service agency Module 7. Characterize drinking water risks from source to tap Module 8. Propose a drinking water risk management strategy It is apparent that Modules 1 and 2 of the Source to Tap Guideline encompass Steps 2 and 3 of the Well Protection Toolkit, and that the remaining six modules address other components of the drinking water system which are not specific to groundwater sources. As such, it is understood that an assessment completed using the methodology of the Well Protection Toolkit could easily be included as part of a larger Source to Tap Guideline Assessment, should it be required at a later date. 3.2 Step 2 - Define Well Protection Areas To efficiently manage and protect a groundwater supply, the well protection area must be defined. This requires an understanding of the source of groundwater that is removed from an aquifer and the definition of the well "capture zone" and the "time-of-travel" zones. During the pumping of a water production well, groundwater is removed from a finite volume of the aquifer. In the initial phases of pumping, the drawdown cone created by the well expands and groundwater is removed from storage within the aquifer (due to Golder Associates

12 December pore drainage, aquifer matrix compression, and water compressibility). In later stages, once the drawdown cone attains sufficient dimensions and/or intersects a water body, groundwater flows radially towards the production well and the aquifer is replenished by recharge due to precipitation and/or leakage from streams, rivers, and geologic units bounding the aquifer. A "capture zone" is the area of an aquifer from which all groundwater will eventually arrive at the production well, even after a considerable amount of time. A "time-oftravel" zone is the area of an aquifer from which groundwater will be derived in a predefined amount of time. For example, if the contaminant is released within the 250 day time-of-travel zone, it can be expected to arrive at the production well in approximately 250 days. Once the time-of-travel zones are estimated, protective measures can be implemented within the zones to promote the safety of the water supply. Several methods of capture zone analysis exist including: 1) the calculated fixed radius method (CFR), 2) type curves and analytical equations for capture zone extent, and 3) numerical flow and transport models. The methods vary in their accuracy and applicability, with Methods I and 2 being restricted to a relatively simple groundwater regime, and Method 3 being capable of addressing scenarios with more complicated hydrostratigraphy, hydrogeologic boundaries, and variable pumping scenarios. Based on the hydrogeological regime in the Midway area, and the limited information currently available, particularly with regards to hydraulic gradients and direction of groundwater flow, Golder used the calculated fixed radius methodology (Method 1) to determine time-of-travel zones for the Village. As discussed in Section 5.0, there was insufficient information available to assess the time-of-travel capture zones by Method 2. Information regarding the characteristics of the aquifer was obtained from the following sources: Information obtained from the MOE Water Resources Atlas regarding the locations of wells, catchment areas, aquifer extent, and water well records; and, Information obtained from the MOE Ecological Reports Catalogue regarding floodplain mapping in the area of Midway (British Columbia Water Surveys Unit and Canada-BC Floodplain Mapping Program, 1991). It should be noted that information obtained from the MOE that is provided in this report for reference purposes is subject to copyright and is reproduced with permission of the Province of British Columbia. For the purpose of this study, Golder Associates carried out a preliminary analysis of the 250-day time-of-travel zones for the Wells No.1, 2 and 3. Although Well No.3 is not currently being used, we have assessed a potential capture zone for this well, should it be Golder Associates

13 December brought into operation. Based on our current understanding, a 250-day time-of-travel zone delineates the approximated maximum time required by biological pathogens moving in groundwater to degrade (Taylor, et. ai, 2004). In order to conduct the time-oftravel zone analysis, Golder examined data regarding the annual pumping volumes of Well No.1 and 2 for the years 2005, 2006 and 2007, which were provided by the Village of Midway (Table 1). It is understood that the actual usage period of Well No. 1 is from the beginning of April until the end of December (275 days) and the usage period of Well No.2 is from the beginning of January until the end of March (90 days). Therefore, the time-of-travel zones for each well were estimated for the following scenario: Well No.1 is pumped at a rate of 13.4 Lis (212 US gpm), which is the average pumping rate of the well during the 275 day period of operation of the well in 2006, the year with the largest recorded pumping volume for Well No.1; Well No.2 is pumped at a rate of 3.8 Lis (60 US gpm), which is which is the average pumping rate of the well during the 90 day period of operation of the well in 2005, the period with largest recorded pumping volume for Well No.2; and, Well No.3 is pumped at a rate of 17.2 Lis (273 US gpm), which is the sum of the pumping rates for Well No.1 and 2. Although Well No.3 is not in use by the Village, an estimate of pumping rate is required in order to conduct the time-oftravel zone analysis; therefore, in order to obtain a conservative estimate of the time-of-travel zone, a pumping rate which reflects the maximum recorded groundwater extraction rate by the Village was utilized in the analysis. 3.3 Step 3 - Contaminant Inventory A contaminant inventory was carried out to identify existing and potential sources of groundwater contamination within the Village of Midway. The inventory was comprised of two components: 1. A regional inventory to identify general environmental concerns in the area of the Village; and, 2. A comprehensive inventory of the Village wells' time-of-travel capture zones. A summary of information sources used to complete the regional and time-of travel capture zone contaminant inventories is presented below. A search of the MOE Contaminated Sites Registry database, to identify properties contained within the database that are located within the Study Area. Golder Associates

14 December Interviews with Mr. John Boltz, Village Public Works Foreman, regarding the status of each well, the extent of sanitary sewers, and any potential environmental concerns. Discussions with Mr. Jim Madder (Village Administrator) and other Village staff regarding locations of private irrigation wells and abandoned wells. Review of Village maps showing land use zoning. Visual inspections of the wellheads for Village Wells No.1, 2 and 3. Site reconnaissance oftime-of-travel capture zones. 4.0 STUDY AREA o Location and Climate Midway is located within the southern interior of BC, approximately 1 km north of the CanadalUnited States Border and approximately 25 km west of Grand Forks, Be. Long-term climate data for the area was collected from the nearby climate stations operated by Environment Canada, located in Midway and Grand Forks, Be. The Midway climate station has records for the period 1987 to 2007, while the Grand Forks station has data for the period 1941 to According to these records, the area is characterized by warm, dry summers and cool, wet winters, with the lowest mean monthly precipitation occurring in September, and the highest mean monthly precipitation occurring in December. The average annual temperature in the area is 7.7 T. The mean annual precipitation for the Grand Forks climate station is 475 mm, while the mean annual precipitation for Midway is 457 mm. Based on the long-term data available for the Grand Forks climate station, the area has received greater than average precipitation since the period from 2000 to 2003, during which time precipitation was slightly below average. o Topography and Drainage The Village of Midway is located within the Kettle River Valley, a wide, U-shaped valley located on a previous flood plain of the Kettle River. The Kettle River is located along the Village's southern boundary and flows west to east through Midway until it reaches the confluence of Boundary Creek, located near the eastern limits of the Village (Figure 3). Downstream of Boundary Creek, the Kettle River flows southeasterly into the state of Washington, USA Most of the Village is located within the valley bottom where the topography is relatively flat. The elevation of the Village varies from approximately 590 m above sea level (m asl) in the western portion of Midway to 575 m asl at the confluence of the Kettle Golder Associates

15 December River and Boundary Creek. The highland areas to the north and south of the Village rise to over 1,000 m asl. Many minor creeks and ephemeral streams, which drain the upland areas, enter the Kettle River in the area of the Village, including Murray Gulch Creek (Figure 3), which drains areas to the north of the Village. The drainage area of Boundary Creek extends through the Kettle Provincial Forest into the Monashee Mountains in the area of Greenwood (Figure 3). No major lakes are present in the area. o Overview of Surficial and Bedrock Geology The surficial geology of the study area is characterized by Quaternary sediments that were deposited along the Kettle River and alluvial fan deposits from Murray Gulch Creek and Boundary Creek. These deposits extend to approximately 1200 m upslope on the north side of the Kettle River and approximately 500 m on the south side of the river. Based on a review of selected well logs from the MOE WRA for wells completed within the Village, the surficial geology in the area of the Village wells consists of interbedded layers of sand and gravel with some clay, silt, and boulders of varying thicknesses throughout the aquifer, to maximum depths of 41 m below ground surface (m bgs). Because the less permeable or confining materials are discontinuous across the aquifer, the aquifer is considered to be semi-confined in nature. The bedrock in the area provides a physical boundary within which the unconsolidated sediments of the Kettle River Valley are situated. The bedrock in the area of Midway consists predominantly of Penticton Group volcanics, comprised of undivided alkalic and calcalkaline volcanic rocks. The area also contains some Post Accretionary syenitic to monzonitic intrusive rocks (MOE WRA, 2007). Well logs obtained from the MOE WRA did not indicate the depth to bedrock in the area of the Village. According to the MOE WRA, there is one normal fault located near the eastern boundary of the Village, which is oriented in a north-south direction and traverses the path of the Kettle River. o Aquifer Characteristics A search of aquifer locations in the BC MOE online mapping program imap BC (BC MOE, 2008) indicated the presence of a single sand and gravel aquifer in the vicinity of the Village of Midway (Appendix II). This aquifer, identified as Aquifer No. 478, has a relatively high productivity, high demand and high vulnerability. The total area of the aquifer extent, as identified by the BC MOE is approximately 360 ha (Figure 3). Golder Associates

16 December o Groundwater Flow Direction Based on the premise that the groundwater table is a subdued replica of surface topography, it is expected that groundwater flow in the area of the Village is from the upland areas in the north towards the Kettle River in the south. It is also expected that a secondary component of groundwater flow is influenced by the easterly to southeasterly flowing Kettle River and by water levels in the River. In order to develop an understanding of the groundwater flow direction in the area, groundwater elevations were calculated for the Village wells based on static water levels recorded during pumping tests conducted by Kala (1995a and 1995b) (Figure 2). In addition, groundwater level information contained in well logs obtained from the BC MOE Wells was examined. Ground elevations used in the estimation of water levels were taken from a floodplain mapping study (British Columbia Water Surveys Unit and Canada-BC Floodplain Mapping Program, 1991) available from the online BC MOE Ecological Reports Catalogue, as these were the most detailed ground elevations available for the area. The water level information from the above mentioned wells indicates that, on the north side of the Kettle River, groundwater elevations are generally higher in the northern and western Village areas, while groundwater elevations are lower in the southern and eastern Village areas. This supports a southerly to southeasterly groundwater flow direction through the Village of Midway. It should be noted that water levels obtained from well records are only an estimate due to the limitations in using water levels recorded in different years and in differing seasons, and due to the fact that well locations and elevations were estimated, given a lack of data in this respect. Copies of well records used in the review of water level information for the aquifer are provided in Appendix III. No hydrometric station is present in the immediate vicinity of the Village, and as such, River elevations in the Village area could not be assessed relative to local groundwater levels. However, based on available information, it is possible that surface water elevations within the Kettle River impact the groundwater flow direction in the area of the River. Specifically, during freshet (spring runoff) when water levels within the River are high, it is possible that there is a component of surface water recharging local groundwater. During times when the surface water elevation within the River is lower, local groundwater may recharge the River. However, based on limited information the relative influence of recharge from the upland areas to the north, and contributions from the River on the direction of groundwater flow cannot be assessed at this time.

17 December HYDROGEOLOGICAL ASSESSMENT 5.1 Village of Midway Wells The following provides a summary of the available information regarding the known construction details, pumping test information and conditions encountered during drilling for each of the Village of Midway wells. A summary of well information is provided in Table 2 and copies of the well records are provided in Appendix IV Well NO.1 According to Mr. Boltz, Well No. 1 is the main Village well and is utilized during the summer months, approximately from the beginning of April until the end of December. According to the driller's log (Kala, 1995b), Well No.1 is 300 mm in diameter and is completed at a total depth of 29.5 m bgs. Conditions encountered during drilling consisted of sand and gravel to a depth of 10.7 m bgs, followed by compact sand and gravel with some clay to a depth of 15.2 m bgs. This was further underlain by interlayered sand and gravel to 29.6 mbgs. Drilling ceased in a deposit of sand between 29.6 m bgs and 30.5 mbgs. The well was completed with 120 slot and 150 slot telescopic stainless steel screen set from 23.1 to 29.5 m bgs. The static water level was recorded to be approximately 8 m bgs at the time the well was drilled. Following completion of Well No.1, Kala conducted a series of aquifer response tests on the well. Initially, a step-drawdown test was conducted at rates ranging from 12.6 Lis (200 US gallons per minute (gpm)) to 52.5 Lis (832 USgpm). The step-drawdown test was followed by a constant rate pumping test which was performed at a rate of 50.5 Lis (800 USgpm). The static water level at the time of testing was approximately 8 m bgs, with a total drawdown observed during the constant rate test of 2.4 m. According to Kala (1995b), results of the aquifer testing indicated the presence of a boundary condition reached after 50 minutes of pumping, which was interpreted to represent the drawdown cone reaching a zone of lower permeability deposits. Kala utilized data from the steepest part of the drawdown curve to obtain a theoretical safe, long term yield of 94.6 Lis (1500 USgpm); however, it was noted that the screen transmitting capacity of the well is less than this value, 78.9 Lis (1250 USgpm), at the maximum recommended entrance velocity of 0.03 m/s. Based on the pumping data provided by the Village, the average pumping rate of 13.4 Lis (212 US gpm) is approximately 13% of the screen transmitting capacity and the maximum recorded daily pumping rate of 49.5 Lis (785 US gpm), recorded on July 11, 2007 is approximately 63% of the screen transmitting capacity.

18 December A well head assessment for Well No.1 was completed as part of the site reconnaissance conducted by Golder on July 18, The assessment was conducted for the purpose of determining whether the Well is completed in accordance with the guidelines of the GWPR. The assessment was based on a visual inspection of the well and information available on the well record. It should be noted that any well constructed prior to the enactment of the GWPR in 2005 is not required to meet the guidelines unless work is undertaken on the well; however, the assessment is useful for determining potential risks of contamination to the well for groundwater protection purposes. Based on the available information, Well No.1 meets the GWPR requirements for flood proofing; however, a well ID plate is not present and the presence of a surface seal could not be verified. Based on the age of the well (1995), it is inferred that a surface seal may not be present, as this requirement was not in place prior to During the site reconnaissance, an attempt was made to measure the static water level in the Well; however, the access port in the well cap was not large enough to allow passage of the water level tape Well NO.2 According to Kala (1995a), very little information is available regarding the construction of Well No.2, other than it is apparently constructed of 200 mm casing and, based on Kala's field measurements, is completed to a depth of at least 16.8 m. The type of well screen used in the construction is not known. According to Mr. Madder, Well No.2 was constructed for a private land developer and later acquired by the Village. On March 23, 1995, Kala conducted a 22-hour pumping test on the well at a pumping rate of 8.7 LIs (138 USgpm). The total drawdown observed during the test was 6.6 m and complete recovery was achieved after three minutes following the cessation of pumping. Based on the pumping test results, Kala recommended a long-term pumping rate of 7.6 LIs (120 USgpm), which was based on utilizing 73 percent of available drawdown and an assumption that the top of the well screen, or perforated section of well casing, was located at 16.8 m below ground surface. According to Mr. Boltz, Well No.2 is utilized during the winter months, generally from the end of December until the beginning of April, when there is little irrigation demand in the community. The average pumping rate of the well is approximately 3.8 LIs (60 USgpm), which is approximately 50% of the recommended long-term pumping rate determined by Kala. A well head assessment for Well No.2 was completed as part of the site reconnaissance conducted by Golder on July 18, The assessment was conducted for the same purpose and in the same manner as described in Section Based on the available Golder Associates

19 December information, Well No.2 meets the GWPR requirements for flood proofing in that the stickup is sufficient and the site grading directs water away from the well. In addition, a well ID plate is not present and the presence of a surface seal could not be verified. Although the exact age of the Well is not known, it was drilled prior to 1995; therefore, it is inferred that a surface seal may not be present, as this requirement was not in place before that time. During the site reconnaissance, an attempt was made to measure the static water level in the Well; however, there was no access port in the well cap that could be used for this purpose We1lNo.3 As previously mentioned, Well No.3, identified by the Be MOE Well Tag Number (WTN) 36524, is a former irrigation well that is not currently used by the Village. A copy of the well record is provided in Appendix IV. It is understood that Well No.3 was drilled in 1977 and operated as MOE Observation Well Number 263 from 1980 until 1984, when it was acquired by the Village of Midway for use as a production well. Apparently, use of this well for domestic water purposes was discontinued when Well No.1 was drilled in According to Kala (l995a), Well No.3 was originally completed as a large diameter, dug well and was later deepened by drilling to a total depth of 19.8 m and completed with a 300 mm or 350 mm diameter steel casing which was not screened, but rather perforated in the main water-bearing zone. In 1981, the well was tested at rates of up to 42.7 Lis (677 USgpm). On March 22,1995, Kala conducted a 24-hour variable-rate pumping test on the well, whereby the initial pumping rate of 14.4 Lis (228 USgpm) was increased to a final rate of 32.6 Lis (517 USgpm) in a step-wise manner. The total drawdown observed during the test was 5.1 m. Based on the pumping test results, Kala recommended a long-term pumping rate of 30.3 Lis (480 USgpm), which was based on utilizing 75 percent of available drawdown and an assumption that the top of the perforated section of well casing was located at 16.8 m bgs. It should be noted that Kala (l995a) recommended that Well No.3 be developed using a cable tool drilling rig prior to it being used as a production well, as the test pump was clogged with debris during testing. Golder could not confirm whether or not the recommended well rehabilitation was completed. A well head assessment for Well No.3 was completed as part of the site reconnaissance conducted by Golder on July 18, The assessment was conducted for the same Golder Associates

20 December purpose and in the same manner as described in Section Based on the available information, Well No.3 meets the GWPR requirements for flood proofing; however, a well ID plate is not present and it is unlikely that a surface seal is present as there is an annular space around the well casing Well NO.4 (Abandoned Village Office Well) A search of the BC MOE Wells revealed a well record (WTN 23000), indicating that a well, herein referred to as Well No.4, owned by the Village of Midway, is located in the vicinity of 8 th Avenue and Eholt Street, near the Village Office. During the Site reconnaissance, Village of Midway staff were not aware of this well; however, a subsequent search of historic documents by the Village Public Works Foreman confirmed the existence of this well (Appendix V). It is not known whether or not the well is currently connected to any infrastructure. The BC MOE well record indicates that the well was drilled in 1969 to a total depth of 16.2 m. Subsurface conditions encountered during drilling consisted of interlayered sand and gravel along the entire soil profile. The static water level at the time of drilling was 9.1 m bgs. The yield of the well estimated by the driller was approximately 3 Lis (45 USgpm). 5.2 Other Groundwater Users A search of the BC MOE Wells database revealed the presence of74 wells in the area of Aquifer No. 478, including one well located at the High School approximately 60 m southeast of the Village Well No. 1. For reference purposes, a plan printed from the Water Resources Atlas, showing the well locations and aquifer extent, is provided in Appendix II. A cursory review of the well records indicates that the wells in the valley area of Midway are generally completed to depths of approximately 15 m bgs and that well depths increase to between 30 and 45 m bgs in the upslope areas to the north of the Village. The depth to groundwater in these wells, as recorded at the time of drilling, ranged from approximately 3.5 m bgs near the Kettle River to approximately 23 m bgs in the furthest upslope well. 5.3 Aquifer Transmissivity In order to obtain an estimate of the aquifer transmissivity, historical pumping test data for the Village Wells No.1 and 2 (Kala 1995a and 1995b), which was provided by the Village, was re-analyzed by Golder using the software package AQTESOLV Professional Version Brief descriptions of these pumping tests were provided in Section 5.1. Due to fluctuating pumping rates and the fact that the test for Well No.3 was of short duration (24 hours), the data collected during the pumping test conducted on Golder Associates

21 December Well No. 3 was not sufficient for the purpose of determining aquifer transmissivity. Based on the analysis of the above mentioned data, the aquifer transmissivity in the area of Well No. 1 is approximately 12,000 m 2 /day and the transmissivity in the area of Well No.2 and Well No. 3 is approximately 170 m 2 /day. This estimate is based on an assumed aquifer saturated thickness of approximately 20 m, taken from the static water level to the base of the aquifer, which, for the purposes of this report, is defined as the total depth of Well No.!. The resulting estimate of hydraulic conductivity for the aquifer varies by an order ofmagnitude and ranges from 1x10-4 m/s to 6x 10-3 m/s. 5.4 Aquifer Water Balance Recharge For the purpose ofthis investigation, estimates of recharge to Aquifer No.478 were made by estimating the volume of precipitation infiltrating the subsurface based on climate data. An assessment of recharge based on the volume of water required to sustain groundwater flow through the aquifer using Darcy's Law was not possible due to the uncertainty in the groundwater flow direction, hydraulic gradient and hydraulic conductivity values for the aquifer. It has been assumed that groundwater recharge to Aquifer No. 478 is primarily via infiltration of precipitation and snow melt to the subsurface in the Murray Gulch Creek watershed, which according to information available from the BC MOE WRA, is primarily located to the north of Midway and covers an area of approximately 30 km 2 The watershed area is outlined in Figure 3. Since Boundary Creek enters the Kettle River downstream of the Village, its watershed area was not considered to recharge this aquifer. The distribution of recharge between the bedrock and areas infilled with alluvium is unclear; however, it is assumed that the aquifer is recharged in part by flow from the adjacent bedrock and that, when lowered through groundwater withdrawal, additional recharge will be induced from the adjacent bedrock. Hence, it is inferred that recharge to the bedrock is, in part, available to the alluvial aquifers. As previously stated, the mean annual precipitation in the Midway area is 457 mm/yr. Based on basin-wide estimates of recharge from a study currently being conducted by Golder in the southern Okanagan Basin, it is estimated that approximately 10% of this precipitation, or 46 mm/yr, is available as recharge. Furthermore, of the total available recharge, it is estimated that, generally, approximately 10% contributes to bedrock and that 90% contributes to alluvial aquifers. Therefore, a preliminary estimate of the annual groundwater recharge from the Murray Gulch Creek watershed is 1,230,000 m 3 /yr (based on an area of 30 km 2 ). This recharge estimate is based on precipitation only, and does not account for other sources of recharge such as contributions from septic disposal Golder Associates

22 December to ground and irrigation, or the infiltration of surface water from the Kettle River to the underlying aquifer Extraction An accurate quantification of the total annual groundwater extraction in the Midway area cannot be made due to the absence of data concerning the number of private wells currently in operation. However, an approximation of the annual extraction rate was calculated for the Midway area by estimating the water usage based on measured pumping rates from the Village Wells and estimates of groundwater withdrawals within irrigated/agricultural areas. The following outlines the assumptions used in developing aquifer discharge estimates: Based on pumping data provided by the Village of Midway, the annual groundwater extraction for Well Nos. 1 and 2 is approximately 347,000 m 3 /y. It is assumed that the High School well pumps at a rate equal to the yield estimated at the time of drilling which is 9.5 Lis (150 US gpm) for three hours per day for 200 days per year (5 days per week for ten months per year). This results in an annual groundwater extraction rate of approximately 21,000 m 3 /y. In addition, Village of Midway staff indicated the presence of six privately-owned irrigation wells in the area of the Village. Since the pumping rates of these wells were not known, the annual irrigation demand was calculated based on the area of irrigated cropland within the Village boundaries on the north side of the Kettle River, based on examination of air photos. The area of irrigated tree farms appears to be approximately 475,000 m 2, while the area of other irrigated crops, for the purpose of this estimate, assumed to be alfalfa, appears to be approximately 1,380,000 m 2 The irrigation demands were calculated using the method outlined in the British Columbia Ministry of Agriculture, Food and Fisheries Irrigation Factsheet, "Guide to Irrigation System Design with Reclaimed Water", published in The estimated annual crop water requirement for the tree farming area is approximately 142,000 m 3, while the estimated annual crop water requirements for the area assumed to cultivate alfalfa is approximately 413,000 m 3. These estimates are based on a maximum soil water deficit calculated for a sandy soil and the average seasonal irrigation requirement for Creston, BC, which is the closest location to Midway with available information that is of a similar elevation and latitude. Therefore, for the purpose of conducting this water balance, it is assumed that the annual groundwater extraction for irrigation purposes in the Study Area is approximately 555,000 m 3 /yr. For the purposes of this report, it is estimated that the annual groundwater extraction from the aquifer is in the order of approximately 1,000,000 m 3 /y. It should be noted that the estimate of groundwater extraction for irrigation purposes is considered to be Golder Associates

23 December conservatively high as i) it is assumed that the entire area identified as "agricultural" is irrigated for crop purposes, which may not be the case, and ii) it assumes that none of the water from the Village of Midway wells is used to irrigate agricultural land in the Village Area Net Water Balance Although the exact volume of water withdrawn from the aquifer cannot be accurately quantified based on available information, it has been estimated that approximately 1,000,000 m 3 of groundwater is currently withdrawn each year from the aquifer. Since the climate based recharge estimate indicates a potential recharge rate of 1,230,000 m 3 /yr, the annual withdrawal represents approximately 80% ofthe available recharge. The above estimate of the groundwater extraction as a percent of available recharge is considered conservatively high as it does not account for the fact that water withdrawn from the system by the community is reintroduced to the ground surface in the form of septic disposal to ground, waste water disposal and irrigation. While the amount of recharge from these sources cannot be accurately quantified, their combined influence would reduce the total net water withdrawn from the aquifer. Note the water balance does not account for other surface water uses in the catchment areas, such as licensed withdrawals from creeks and rivers. 5.5 Preliminary GWUDI Assessment A preliminary GWUDI (Groundwater Under the Direct Influence of surface water) assessment was conducted for the Village Wells. Although no regulations regarding GWUDI are currently present in BC, the BC MOE has recently issued a draft guidance document entitled "Draft Guidance Document for Determining Ground Water at Risk of Containing Pathogens and Ground Water Under Direct Influence of Surface Water", dated December 14, According the BC MOE draft document, a well can be "flagged" as potentially under the direct influence of surface water if it satisfies one of the following initial screening criteria: A groundwater well located within approximately 120 m from a cemetery or dumping ground, within 6 m of a dwelling or within 30 m of a probable source of contamination (MoH, 1996). Any groundwater source or water supply well that has an intake depth of less than 15 m below ground surface within a floodplain area or is located less than 100 m outside the high water mark of a surface water, stream, or stream channel. Golder Associates

24 December Any groundwater source or water supply well with an intake depth greater than 15 m below ground surface and is located less than 100 m outside of the high water mark and that are at or below the elevation level of the high water mark. Well with an intake depth ofless than 15 m below ground surface and is situated in a highly vulnerable, unconfined, unconsolidated aquifer or in a bedrock aquifer. Well construction fails to meet the Groundwater Protection Regulations. The well regularly contains Total Coliforms, Fecal Coliform or E. coli. We provide the following comments regarding the preliminary GWUDI analyses. 1. The three Village wells are not located within 100 m of a high water mark or flood plain (as identified on the MOE WRA flood plain mapping). 2. Village Well No. 1 has a well screen completed at a depth of greater than 15 m bgs. 3. Available information indicates that Well No.2 and 3 are not completed with a standard well screen, but rather consists of perforated steel casing. The intake depth of the top of the perforations is unknown; however, the depth of Well No.3 is approximately 19.8 mbgs and the depth of Well No.2 is at least 16.8 mbgs. 4. Information regarding well completion details (ie. the presence of a surface seal) does not exist. Based on the age of the wells, it is unlikely that a surface seal was constructed around each well. 5. The three Village wells are not known to be located within 120 from a dumping ground or within 30 m ofprobable source of contamination. 6. The 250-day time-of-travel capture zone for each of the wells (discussed in more detail in the following sections) do not intersect a surface water boundary. 7. An examination of water quality data was beyond the scope of work for this project; therefore, it is unknown whether any of the Village wells contain total or fecal coliform and/or E. coli bacteria. As completion details for the three wells do not meet the BC GWPR (i.e. the presence of a surface seal), the preliminary GWUDI assessment would indicate that the wells could potentially be considered GWUDI. Although additional investigations would be required Golder Associates

25 December to confirm GWUDI status for these wells, this could imply that potential treatment (filtration or chlorination) of the water may be required by the Health Authority. 6.0 WELL PROTECTION TOOLKIT 6.1 Step 1 - Community Planning The development and implementation of the GWPP should be carried out with input from a wide range of community members. Local government bodies, citizens, business owners, farmers and community groups all have an interest in protecting groundwater in the Midway area for domestic, agricultural, commercial and recreational use. At this point the primary focus in the development of the initial stages of the GWPP is technical, and does not require the input from the general public. However, input from the public would be solicited as part of the next phase of the development of the GWPP (Steps 4, 5 and 6), with additional members added to the Community Planning Team at a later date. Based on the scope of work for this phase of groundwater protection planning the community planning team consists of the following persons: Mr. Jim Madder, Village of Midway; Ms. Jacqueline Foley, Golder Associates Ltd.; Ms. Cheryl Unger, Interior Health Authority; and, Mr. Oleg Ivanov, BC Ministry of Environment The purpose of establishing the initial planning committee is to define the GWPP objectives and methodology and to understand the technical issues related to the aquifer in Midway, prior to embarking on public workshops to solicit stakeholder input. 6.2 Step 2 - Define Well Protection Areas Time of Travel Zone Results Estimates of the extent of a 250-day time-of-travel zones were completed for the Village's three wells, using pumping rates of 13.4 Lis for Well No.1, 3.8 Lis for Well No.2 and 17.2 Lis for Well No.3. The basis for selection of pumping rates is outlined in Methodology Section 3.2. For the purpose of these estimates, an aquifer thickness of approximately 20 m was used, which is the distance from the static water level to the base of Well No.1, as no information was available regarding the total thickness of the aquifer. Because using a smaller aquifer thickness provides a more conservative (larger) estimation of the time of travel zone, this estimation was considered appropriate for the purpose of the GWPP. Golder Associates

26 December Due to the uncertainty in the groundwater flow direction, the presence of the Kettle River, which may act as a positive boundary condition, and due to the large range in hydraulic conductivity estimates for the aquifer, it was determined that the analytical method of capture zone analysis was not appropriate. As such, the CFR method was utilized. Details regarding this method of capture zone analysis are presented in Appendix I. The 250-day CFR time-of-travel capture zone for Well No. 1 has a radius of approximately 190 m, while that of Well No. 2 has a radius of approximately 100 m (Figure 4). Based on a theoretical pumping rate of 17.2 Lis, the 250-day time-of-travel capture zone for Well No.3 would have a radius of approximately 210 m (Figure 4). 6.3 Step 3 - Preliminary Contaminant Inventory Results of Regional Contaminant Inventory The results of the regional contaminant inventory are presented below and the locations of relevant land uses are provided in Figure 4. Existing Land Use In general, land use in the Village consists mainly of residential and agricultural uses, with some minor commercial, light industrial and recreational uses. According to the Village Official Community Plan (Appendix VI), the immediate area of the Village wells is predominantly zoned Residential, Rural Residential! Agricultural to the north and west. A small area of light industrial use, consisting of auto repair and mechanic shops, exists along Highway 3 to the west of Well No.3 (Figure 4). A windshield survey and subsequent interview with the Village Public Works foreman were undertaken on July 18, 2008 in order to identify general business activities in the Village was conducted. The following land uses were noted in relation to the location of the Village wells and are shown on Figure 4. A gasoline service station is located near the junction of Palmerston Avenue and Florence Street. The presence of a bulk fuel station located near the junction of Palmerston Avenue and Cleghorn Street. Golder Associates

27 December Contaminants of concern commonly associated with these land uses include fuel hydrocarbons, oil and grease, chlorinated solvents, volatile organic compounds, and metals. Agricultural Land Use A review of the Village of Midway Official Community Plan (OCP- VI) indicates that agricultural land use predominates to the north of Highway 3. Groundwater contamination from agricultural land use can result from the use and storage of animal manure and the application of chemical fertilizers and pesticides. The potential for groundwater contamination from agricultural properties can be low to high, depending on the degree of compliance with the agricultural codes. Contaminants of concern typically associated with animal manure include E. Coli and other coliform bacteria, antibiotics, and organic nitrogen; the latter of which is frequently a source of nitrate in groundwater. The risk of groundwater contamination will also depend on the nature and volume of chemicals used and stored, disposal practices and the presence and maintenance of storage tanks and on-site sewage disposal systems. Similar chemical applications that are used on agricultural properties may also be used on residential lawns and parklands. Residential Properties Numerous residential properties are located within the Village boundaries. Residential properties were noted in the vicinity of Village wells No.2 and 3. Some sources of groundwater contamination potentially associated with these properties could include lawn care chemicals, common household products, and wastes related to property maintenance and automotive repair. Recreational Parkland Based on the Village OCP, the following three areas of recreational park land were identified: The high school playing fields are located immediately north of 5 th Avenue, approximately 150 m east of Well No.1; A municipal park located along Cleghorn Street, approximately 50 m north of Well No.2; and, A campground located on the north bank of the Kettle River at Florence Street. Sources of groundwater contamination potentially associated with recreational land use include lawn care chemicals. Golder Associates

28 December Ministry of Environment Contaminated Site Registry Golder conducted a review of the BC MOE Site Registry system, which identifies those properties for which the MOE holds environmental information. These records are limited to information obtained since approximately The existence of a property within the Site Registry system does not necessarily imply that the property is contaminated, as under the existing Contaminated Sites Regulation, the site registration process can be triggered by a number of mechanisms, including property transactions and facility upgrades, and not only subsurface contamination. Similarly, there may be a number of contaminated sites within the Village that have not been identified by the Site Registry. Based on the results of the search, only two properties of environmental concern were registered on the Site Registry within a 5 kin radius centered on a latitude of 49 00'27.7" N and a longitude of '29.8"W. The following summarizes the information regarding the two properties on the Site Registry. In the documentation, the locations of both sites were indicated as approximate. Copies of the detailed site reports are provided in Appendix VII. 1. Site ID 2529: This site is located at 49 00'51.1" Nand '27.0"W, and is approximately 1100 m to the west and outside of the Study Area boundary. According to information on the Site Registry system, the status of the site is identified as "inactive-no further action". Available information states that the MOE authorized a one time discharge of material to the air during testing and cleaning of a natural gas pipeline which runs parallel to Highway 3. Based on the nature of the potential contaminant source (gaseous), the one time release and the location of the release outside of the Village boundary, it is unlikely that this site represents a potential environmental concern to the Village wells. 2. Site ID 5108: The site is located north of the airfield, approximately 875 m to the west of Well No.3. The location of this property relative to the Village wells is shown on Figure 4. According to information on the Site Registry system, the status of the site is identified as "inactive-no further action". The record states that a Stage 2 Preliminary Site Investigation was conducted for the Midway railway crossing realignment, the results of which indicated soil contamination was present from hydrocarbons or heavy metals at a level above limits for agricultural use, but below levels of concern for urban park, residential, commercial and industrial use. Due to the reported removal of the contaminated soil, it is unlikely that this represents an environmental concern to the water quality within the Village wells. Golder Associates

29 December Sewer Systems According to a representative from the Village, the majority of the Village is serviced by a municipal sanitary sewer system. The Village sewage treatment plant, which, according to Mr. Madder, consists of a clarifier and discharges treated effluent to the Kettle River, is located on the south side of the Kettle River, near the southern boundary of the Study Area (Figure 4). Some properties within the Village limits are not connected to the municipal system and are serviced by private onsite septic systems. Of these properties, 18 lots are located immediately to the north and south of 14 th Avenue, and one large lot is located immediately west of 13 th Avenue. These properties are approximately 400 m to the northwest of Well No.3. In addition, an area of onsite septic system use was indicated on a group of three small lots which are bounded by Highway 3 to the north and by the Village airstrip to the south which are located approximately 300 m to the southwest of Well No.3 and approximately 600 m to the northwest of Well No.2. Areas within the Village boundary with identified onsite septic system use are shown on Figure 4. It is understood that the campground on Florence Street is serviced by the Village sewer system and does not utilize an onsite septic system. Septic systems are common sources of groundwater contamination, contributing bacteria, viruses, nitrates, detergents, oils and chemicals to groundwater. Groundwater contamination from septic systems results in cases where systems are poorly sited, designed or constructed, where systems are poorly maintained, or where septic system densities are too high to allow sufficient renovation. Storm Water Disposal Golder understands that the storm water within the Village's boundary is predominantly infiltrated directly into the subsurface through unlined ditches adjacent to roadways. Storm water runoff commonly contains contaminants such as oils, metals, antifreeze and biological constituents which could potentially be transmitted directly to the aquifer at the storm water discharge location. Existing and Abandoned Water Supply Wells According to the MOE WRA, a total of 74 water wells (one of which is apparently an abandoned Village well: Well No.4) are present within the area of Aquifer No. 478 (Appendix II). An inventory of these wells was not conducted as part of this assessment; however, it can be inferred that a significant number of these wells were once in use as private water supply wells prior to upgrading of the Village water system in Golder Associates

30 December Presumably, some of these wells may still be used by private well owners as a secondary source of water supply, while others have been subsequently abandoned. Based on discussions with the Village Public Works Foreman, Village records indicate the presence of 32 private wells within the Village. It is not known how many of these wells are in use; however, it is understood that at least six private irrigation wells are still in use within the Village boundaries. The approximate locations of these irrigation wells, as provided by Village of Midway staff, are identified on Figure 2. Improperly abandoned wells can provide direct conduits for the migration of surface contaminants to the underlying aquifer. In some cases, abandoned wells are used for the disposal of wastes such as motor oil. Because improperly abandoned wells provide direct pathways to underlying aquifers, their presence represents a threat to groundwater. If some residences utilize private wells as a secondary water supply, the potential exists for back-flow from the private water supply system into the Village water supply system. Transportation Corridors Highway 3 is a major transportation corridor that is situated in an east to west direction on the north side of Midway's downtown area. It is located approximately 250 m north of Well No.1 and approximately 125 m south of Well No.3. In addition to a major highway, two former rail lines and an active airstrip are located in the Study Area. As transport trucks and airplanes have the ability to carry cargo that could create a potential environmental concern if spilled, these transportation corridors are generally identified as issues of concern within the area of water wells. Fuel storage and fuelling of airplanes presents concerns for contamination by hydrocarbons. Incidental releases of fuel and mechanical fluids from vehicles and aircraft can also impact storm water runoff which may in turn serve as a source of groundwater recharge. In addition, if the ballast materials have not been removed from the former rail lines, these areas may be identified as issues of concern due to metal and hydrocarbon contamination commonly associated with rail ballast materials. In addition to the above, based on our reconnaissance of the area around Well No.2, it was identified that a dust suppression agent is used on the gravel road adjacent to the well house. The specific composition of the dust suppression agent is unconfirmed Results of Contaminant Inventories for Capture Zones Contaminant inventories of the 250-day time-of-travel capture zones were conducted by means of the field reconnaissance, and focused mainly within the boundary of Aquifer No The inventory did not include interviews with private property owners or site- Golder Associates

31 December specific inspections. Other than the information contained within the MOE Site Registry, the inventory did not include a review of historical site activities. The following table presents the results of the contaminant inventory within the various time-of-travel zones of the Village wells. Table 3 - Contaminant Inventory within Time-of-Travel Capture Zones Well 250-day Time-of-Travel Zone No.1 No.2 No.3 Residential Land Use Agricultural Land Use Recreational Land Use Residential Land Use Residential Land Use Agricultural Land Use Highway #3 High School Well Private Irrigation WeIll Potential Abandoned Wells I Recreational Land Use Former CPR Line Private Irrigation WeIll Potential Abandoned WeIll I Location(s) unconfirmed Results of Contaminant Inventories for Well Heads No additional contaminants of concern were noted during the well head assessment of Well No.1, while the results of the well head assessment for Well No.2 indicated that a dust suppression agent is periodically used on the gravel road adjacent to the well house. The specific composition of the dust suppression agent is unconfirmed. Items noted during the well head assessment of Well No.3 include the storage of a pail of an unconfirmed substance in the well house and the presence of a black, tarry substance spilled on the floor in one area of the well house Contaminant Inventory Summary Based on the results of the contaminant inventory review it was noted that the majority of the area around Midway contains residential, agricultural and undeveloped land. In general, land uses of concern identified within the 250-day time-of-travel capture zones of the active Village Wells, No. I and 2, consisted of active and potentially abandoned wells, and agricultural, recreational and residential land uses. Land uses of concern identified within the 250-day time-of-travel capture zone of the inactive Village Well, No.3, consisted of residential and agricultural land, transportation corridors (Highway #3 Golder Associates

32 December and the former CPR line), and potentially an abandoned well. Items of concern noted during the well head assessments consisted of the usage of a dust suppression agent immediately adjacent to the well house of Well No.2 and the storage of a pail of an unconfirmed substance in the well house and the presence of a black, tarry substance spilled on the floor in one area of the well house of Well No CONCLUSIONS Based on the results of this Study, the following conclusions are made; The aquifer in the area of Midway (Aquifer No.478) is a sand and gravel aquifer, which ranges from unconfined in the vicinity of Wells 2 and 3, to semi-confined in the vicinity of the Village Well No. 1. The estimated aquifer thickness is approximately 20 m. The Village operates two wells to supply potable water to its residents. A third well is being considered as a backup potable water supply for the Village. In addition, a fourth out-of-use well was identified in the area of the Village Office. It is inferred that groundwater flow in the area of the Village is from the upland areas in the north towards the Kettle River in the south, with a southeasterly component of flow as a result of the southerly/southeasterly flowing Kettle River. It is also expected that another component of groundwater flow is present in the area of the Village and is controlled by water levels in the Kettle River. Well No.1, the main Village well, was constructed in 1995 and is completed with a conventional telescopic stainless steel screen, while Well No.3 is not completed with a conventional well screen assembly and the well screen construction for Well No.2 is not known. The average recorded pumping rates of Well No.1 and 2 are 13.4 Lis (212 US gpm) and 3.8 Lis (60 US gpm), respectively. Well No.3 was previously used as an irrigation well; however, it is not currently in use. For the purposes of assessing a potential 250-day time-of-travel capture zone for the well, should the well be re-commissioned, a pumping rate of 17.2 Lis (273 US gpm) was utilized. The results of a well head assessment conducted on July 18, 2008 revealed that the Village wells are not compliant with the GWPR. Deficiencies noted were the absence of well ID plates and the likely absence of surface seals. Potentially, a number of private active and/or inactive water supply wells exist within the aquifer. It is not known how many of these wells are in use; however, it is understood that at least six private irrigation wells are still in use within the Golder Associates

33 December Village boundaries. Improperly abandoned wells can provide direct conduits for the migration of surface contaminants to the underlying aquifer and, private wells utilized can cause back-flow in to the Village water supply system. Based on the preliminary estimates of annual recharge and groundwater extraction, the annual withdrawal represents approximately 80% of the available recharge; however, this estimate is considered conservatively high as it does not account for the fact that water withdrawn from the system by the community is reintroduced to the ground surface in the form of septic disposal to ground, waste water disposal and irrigation. Land uses of concern identified within the 250-day time-of-travel capture zones of the active Village Wells, No. 1 and 2 consisted of active and potentially abandoned wells, and agricultural, recreational and residential land uses. Land uses of concern identified within the 250-day time-of-travel capture zone of the inactive Village Well, No.3, consisted of residential and agricultural land, transportation corridors (Highway #3 and the former CPR line), and potentially an abandoned well. Items of concern noted during the well head assessments consisted of the presence of a private parking space and usage of a dust suppression agent immediately adjacent to the well house of Well No. 2 and the storage of a pail of an unconfirmed substance in the well house and the presence of a black, tarry substance spilled on the floor in one area of the well house of Well No RECOMMENDATIONS The following recommendations are made with regards to continuing the GWPP process for the Village. It is important to note that some of these recommendations may require the combined collaborative effort of the BC MOE, RDKB and the IHA. 1. Presentation of Results It is recommended that the results of the initial phases in the development of a Groundwater Protection Plan be presented to Village council members and the Community Planning Team to receive their input regarding the direction of the plan. Golder Associates

34 December Confirmation of Static Water Levels, Groundwater Flow Direction and Gradient and Refinement of Time-of-Travel Capture Zones As the direction of groundwater flow within Aquifer No.478 could not be confirmed due to the limitations in water level data (water levels collected at different times of the year and poor spatial data), as well as a lack of River elevations, it is recommended that static water levels within the aquifer be confirmed. This would include the verification of wellhead elevations, static water levels within the Village wells and nearby private wells, and surface water river elevations. As there are several groundwater wells completed within the aquifer, consideration could be given to installing water level transducers in some of these wells to reconcile groundwater elevations and flow directions, thereby accounting for seasonal fluctuations in groundwater flow directions. In addition, it is recommended that water level elevations within the Kettle River be measured. This could consist of measuring spot elevations at approximately three locations on the river at the time of the water level elevation survey. One of these locations could consist of a marked stake installed on one of the abutments of the Florence Street bridge for the purpose of regularly recording water elevations in the River. Once groundwater levels, river elevations and hydraulic gradients have been confirmed, the time-of-travel capture zones should be refined. For this purpose, consideration could be given to using either the analytical methodology, or a numerical groundwater model. 3. Confirmation of Water Balance Due to the uncertainty in the water balance for the Midway area, particularly the groundwater extraction rates from the aquifer, it is recommended that the Village attempt to obtain total annual extraction and pumping information from other groundwater users in the Village, namely the private irrigation well owners and the High School. Once the groundwater extraction data is obtained, refinements to the water balance can be provided. 4. GWUDI Assessment Preliminary information indicates that the Village wells can potentially be flagged as GWUDI, mainly due to the lack of a surface seal around the well. As such, it is recommended that the Village consider installing a surface seal around each well, and conduct other works to bring the wells into compliance with the Be Groundwater Protection Regulations (Le., ensure that all caps are securely placed, place Well ID Plates Golder Associates

35 December on wells, etc.). Following confirmation of the groundwater flow direction and gradient, the GWUDI status of the wells may be assessed, taking into consideration the refined time-of-travel capture zones. 5. Completion of Steps 4, 5 and 6 of the WPT The completion of subsequent Steps 4 (Develop Management Strategies), Steps 5 (Develop Contingency Plans) and 6 (Monitor Results and On-going Evaluation of the Plan), as outlined in the Well Protection Toolkit, should be completed as Phase II of the development of a GWPP. The following provides some preliminary comments regarding the scope of the remaining steps. Step 4 - Develop Management Strategies The following section provides preliminary comments regarding the development of groundwater protection management strategies for the Village wells. Designate Groundwater Protection Areas: Following refinement of the capture zone analyses, it is recommended that the portion of Aquifer No. 478 in the Midway area be identified as a groundwater protection area. A groundwater protection area may be defined on the basis of a time-of-travel zone, a capture zone, a portion of the aquifer, or a combination of these, based on local conditions. Considerations for delineation of the groundwater protection area(s) include the extent and nature of the aquifer (unconfined to semi-confined), together with uncertainties related to potential seasonal fluctuations in the direction of groundwater flow. Develop Groundwater Protection Measures Once designated groundwater protection areas have been established, the Village can consider embarking on the development of groundwater protection measures. Groundwater protection measures can be implemented at the municipal/regional level through both regulatory and non-regulatory measures. In our opinion, while nonregulatory measures, such as public education and best management practices can be highly effective, some degree of regulatory control may be required to ensure the protection of the groundwater resources. These regulatory strategies often involve the use of municipal land use planning and zoning bylaws to restrict certain high-risk land use activities within protection areas. Based on the results of the capture zone contaminant inventory, abandoned wells, private water wells, agricultural, recreational and residential land uses and the transportation Golder Associates

36 December corridor (Highway 3), may represent the greatest threats to the Village wells. The development of an emergency response plan, including spill response planning, would address potential concerns related to the presence of a transportation corridor within the aquifer. In addition, the decommissioning of unused wells in the area would reduce the likelihood of potential contaminants entering the aquifer. Additional information regarding well decommissioning is provided below. Golder would be pleased to assist with the development of specific groundwater protection measures once some of the preceding work has been carried out. Some examples of groundwater protection measures that may be considered are presented in Appendix VIII. These measures have been adapted from the Environment Canada/Fraser River Action Plan (FRAP) report entitled "Groundwater Quality Protection Practices" (Golder, 1995), which was prepared by Golder on behalf of Environment Canada. Decommission Abandoned Wells Based on available information it can be inferred that up to 74 potentially abandoned wells are present within Aquifer No. 478 (BC MOE, 2008), including the abandoned Village Office well, herein referred to as Well No.4. It is unclear how many of these are have been completed as water wells or test wells versus boreholes (i.e. casing removed from the ground). In order to ensure that an unused well does not pose a safety risk or act as a conduit for contamination to the subsurface, the BC Groundwater Protection Regulation (GWPR) requires that a well which is unused for 5 years must be either deactivated or closed, and a well that has been deactivated or not used for 10 years must be closed. Note that a well that is actively maintained for future use or for use as a backup water supply is not required to be closed or deactivated. Based on the above, it is recommended that Well No.4 be located and its condition assessed. Furthermore, it is recommended that an assessment be conducted regarding the locations of other potentially abandoned wells and their conditions, such that a determination can be made regarding the potential decommissioning of these abandoned wells. Groundwater Protection Measures at Wellheads Based on the results of the well head assessments conducted as part of this GWPP, the following comments are provided regarding the Village of Midway Wells. Consideration should be given to installing a surface seal at Well No.1. Golder Associates

37 December It is recommended that consideration be given to paving the section of Eholt St. directly adjacent to Well No.2 as it is understood that currently, the road consists of gravel which is periodically wetted down with a dust suppression agent of unconfirmed composition. Due to the unconventional construction of Well No.3 (perforated casing) the age of the well (over 20 years old), the Village of Midway may wish to conduct a well assessment in order to determine whether the well should be upgraded or redrilled using a conventional well screen. It is recommended that the substance being stored in the well house of Well No.3 be identified and removed if it is determined to pose a hazard or if it is not needed at that location. Also, it is recommended that the substance which is spilled on the floor of the well house be identified and that appropriate precautions be taken when cleaning it up. In particular it should be noted that water used to clean up the spill should not be allowed to enter the annular space around the well casing. It is recommended that the annular space visible around Well No.3 be sealed with a bentonite slurry mixture to reduce or eliminate the potential for contaminants spilled within the well house to migrate into the aquifer. Step 5 - Develop Contingency Plan The development of a contingency plan is necessary to ensure that the Village reacts in a timely and efficient manner to a contamination event in the area of the Village Wells. The contingency plan would outline the events necessary to reduce potential impacts of a nearby spill on the water quality within the aquifer and the wells. Specifically, contingency planning involves developing a response to a range of possible contamination events identified for the each of the potential sources listed within the contaminant inventory. In addition, contingency planning identifies alternate sources of water supply in the event that contamination results in the temporary or permanent loss of a water well. The development of an emergency response plan is part of contingency planning. Even under the best prevention plans, a scenario that threatens to contaminate the aquifer may occur. When this happens, an emergency response plan directing a coordinated and timely response is an effective tool for assuring a continued supply of potable water. Many communities' emergency response plans do not include specific provisions for the protection of groundwater or surface water resources in the event of a spill or accident. We recommend that the Village review and re-evaluate their existing emergency response plan (if one is present), and if necessary, revise the plan to allow for the protection of sensitive groundwater resources, as well as the entire water supply system.

38 December Step 6 - Groundwater Monitoring Although a detailed review of the Village groundwater quality monitoring program was not conducted as part of this GWPP, it is recommended that a water supply monitoring plan be developed to monitor both water quality and well performance. Some suggestions for the development of these monitoring programs are presented below. Water Quality Monitoring Based on a review of the time-of-travel contaminant inventory results, it is recommended that the following be considered to be included as part of the groundwater monitoring program: Standard potability analyses should be conducted, at a minimum, annually for any active Village water wells. A baseline analyses for the potential contaminants of concern should be considered for selected wells. As further information becomes available regarding the use of specific contaminants of concern within the maximum groundwater protection area, the baseline analyses should be modified to include any new potential contaminants of concern. Groundwater should be collected using proper sampling protocols. It is recommended that a secure sampling point be provided within the water lines from the wells, such that a water sample can be easily collected from each well. Groundwater samples should be submitted to a Canadian Association for Environmental Analytical Laboratories ("CAEAL") certified laboratory for the analyses. Should a specific contaminant of concern be identified as a result of local contamination within the area, the groundwater sampling frequency and list of parameters should be adjusted accordingly to account for this event. For example, if a fuel truck tips over along Highway 3, spilling its fuel load, hydrocarbon parameters would be added to the list of required analyses at an increased frequency, to ensure that hydrocarbon concentrations were not adversely impacting the water quality. Analytical data should be compiled within a database and reviewed annually by a qualified professional. Adjustments to the groundwater monitoring program would be made, if necessary. Golder Associates

39 December Well Performance Monitoring and Maintenance Routine well inspection (monitoring) and maintenance are mandatory in order to prolong the life of a well. Any changes in the water chemistry and operating characteristics of the well should be closely monitored and dealt with promptly, as both the well and pump can deteriorate beyond repair if problems are left unattended. For non-domestic (municipal) wells completed in alluvial aquifers, the typical frequency for major well maintenance is usually every 5 to 10 years. Down-hole video camera inspection should be completed every 3 to 5 years, or at the same time when down-hole pumping equipment is removed for scheduled inspection In order to continue to monitor well performance, it is recommended that, in addition to the current monitoring of pumping rates, the static and pumping water levels, recorded on a regular basis for the in-use wells (Well No.1 and Well No.2) and that consideration be given to monitoring static (non-pumping) water levels in Well No.3 as it is not in use. Water levels can be collected either manually or using permanently installed data loggers within each well. The purpose of the data logger is to collect water levels within the wells at predetermined intervals. Water levels can then be downloaded monthly for review and analyses. The purpose of the monitoring program is to continue to assess the well efficiency, and determine if additional well rehabilitation is required. 9.0 LIMITATIONS AND USE OF REPORT This report was prepared for the exclusive use of the Village of Midway.

47 APPENDIX I CALCULATED FIXED RADIUS METHOD OF TIME-OF-TRAVEL CAPTURE ZONE ANALYSIS

48 Method 1 - Calculated Fixed Radius The calculated fixed radius (CFR) method depicts a circular time-of-travel area, not taking into account the hydraulic gradient or boundary conditions, and as such, provides for a conservative (likely larger than actual conditions) estimate of the time of travel zones' extent in the direction downgradient from the well. However, it may underestimate its extent in the upgradient direction. The CFR method assumes the aquifer is infinite in extent and homogeneous in nature, and allows the time oftravel zone to extend beyond positive and negative boundary conditions in a circular pattern. Detailed (three-dimensional, transient flow) modeling would be required for more accurate delineation. Nevertheless, time-of-travel zones based on the CFR method are considered sufficient for preliminary delineation ofwellhead protection zones. The CFR method is based on the following equation: Where: Q t r = _1-----=n b r = calculated fixed radius around the pumping well (m) Q = pumping rate (LIs) t = travel time (usually in years) n = aquifer porosity (for sand and gravel aquifer. assumed to be 0.25) b = aquifer thickness or screen length (m) Limitations of Analysis - Calculated Fixed Radius It should be noted that the calculated fixed radius method used to estimate the time-oftravel zones is a calculation that is based on simple physical assumptions of the aquifer system. The CFR method assumes the aquifer is unifotnl and that the groundwater velocity prior to pumping is nil. This method is generally applicable when: I) the hydraulic gradient is relatively small; 2) the aquifer is relatively homogeneous; 3) the pumping rate is relatively high; and 4) the pumping well is located at a significant distance from hydrogeologic boundaries. Considering this, the CFR method is considered to be fairly accurate for travel times up to 60 days. Estimates of zones of travel in excess ofone year are typically a poor representation oftravel time zones. In addition, the calculated fixed radius method does not take into consideration potential interactions of the time of travel zones with large boundaries, such as the Kettle River and Boundary Creek.

49 Limitations at Time-at-Travel Zone Analysis with Respect to Contaminant Transport Time-of-Travel Capture Zone Analysis does not account for the dispersion of contaminants in groundwater. Dispersion as a transport process causes a plume of contaminants to arrive at the receptor earlier than the water particle moving by advection only, and causes the plume to spread at right angles to the direction of the groundwater flow. Thus, it is possible that contaminants originating from a potential source located within the wellhead time-of-travel capture zone will arrive at the production well at a lower concentration, but earlier than that predicted by the model. It is also possible that some contaminants from sources located outside (and nearby) the time-of-travel capture zone boundaries could cross into the time-of-travel capture zone by dispersion and then migrate towards the production wells. Time-of-Travel Capture Zone Analysis does not take into consideration the retardation and degradation of contaminants in groundwater. Retardation is a process that slows down the spreading of contaminants in groundwater, whereas degradation causes a reduction of the mass that originally entered the subsurface. Both processes tend to counteract the effects of dispersion described in the preceding bullet. Depending on the contaminant source, the effect of these processes may be greater or less than the effects of dispersion.
