5 1.0 INTRODUCTION Azimuth Environmental Consulting, Inc. (AEC) was retained by the Region of Peel to conduct a short-term surface water monitoring program for a 7-day pumping test which took place in the Village of Caledon East, Ontario. The pumping rate for the entire 7-day test was approximately 4165 L/min, which began August 7 th, 2013 (9:00 am) and concluded August 14 th, 2013 (10:00 am). The pumped discharge of ground water was split between two surface water receivers, with Walker creek receiving approximately 60% of the discharge and Boyce s Creek receiving approximately 40%. Two stations within Boyce s Creek (Flow 1B and Flow 2B) and two stations within Walker Creek (Flow 1W and Flow 2W) were chosen to monitor flow, water levels, water temperature and water quality before and during the 7-day testing sequence. The locations of the surface water monitoring stations are presented in Figure SCOPE OF WORK The scope of the surface water monitoring program undertaken by AEC was decided upon by the Toronto and Region Conservation Authority (TRCA), Geo Kamp Limited and AEC. The program included the following elements: 1. The establishment of two separate surface water monitoring stations within Boyce s Creek and Walker Creek, one upstream of the discharge point (Flow 1B & 1W) and one downstream (Flow 2B & 2W). Each station included a stilling well/staff gauge equipped with a hydrostatic datalogger to allow for automatic water level measurements and temperature readings to occur on an hourly basis. Periodic surface water discharge rates were also taken at each monitoring station to establish a rating curve for each of the river monitoring locations; 2. A total of three water quality sample sets (one set taken before the test and two taken during the test) were collected at each of the monitoring stations. Laboratory analysis included a wide range of inorganic, metals and nutrient parameters, along with analysis of total suspended solids levels. Turbidity levels were also measured manually in the field during each visit, including daily measurements during the 7- day testing sequence; AZIMUTH ENVIRONMENTAL CONSULTING, INC. 1

6 3. Each monitoring station was visited six times before the commencement of the 7- day pumping test to collect baseline data. Baseline monitoring visits were chosen based on times of varying climatic conditions (when available) to ensure the collection of data occurred during a wide range of flow/water level stages; 4. Each monitoring station was visited once per day during the 7-day pumping test to measure and track any potential impacts the ground water pumping may have had on the surface water receivers; and 5. To analyze the data from each monitoring station, separate rating curves were established using all water level and flow data collected prior and during the 7-day pumping test. The automatic water level data collected throughout the monitoring period allowed for the fluctuations of each monitoring station to be observed on an hourly basis. 3.0 METHODOLOGY 3.1 Level/Temperature Monitoring Between July 18 th and August 16 th, 2013, water levels at each of the surface water monitoring stations within Boyce s and Walker Creeks were measured automatically and verified manually. Each monitoring station was equipped with a stilling well constructed of slotted PVC pipe and a steel T bar. Each stilling well contained a hydrostatic datalogger programmed to collect and record water level and water temperature measurements on an hourly basis throughout the duration of the monitoring period. Each datalogger also collected water temperature data at the same frequency. The stilling wells were removed from each station following the completion of the monitoring period. Manual water level measurements were also taken at each stilling well, which coincided with the manual flow measurements taken (described below) at each monitoring station. 3.2 Flow Monitoring Between July 18 th and August 16 th, 2013, manual flow measurements were taken at each of the surface water monitoring stations using a Swoffer (Model 3000) Stream Flow Meter. To accurately measure stream flow, a measuring tape was extended from the wetted left bank to wetted right bank (facing upstream), and individual river measurements (water level depth and flow velocity) were taken at 0.20 metre intervals AZIMUTH ENVIRONMENTAL CONSULTING, INC. 2

7 across the extent of the wetted channel and then converted to a net stream flow estimated using a trapezoidal integration technique. The manual flow and water level measurements were used to create rating curves for each of the surface water monitoring stations. 3.3 Quality Monitoring On the dates of August 1 st, August 7 th and August 13 th, 2013, water quality samples were collected at each surface water monitoring station. One sample was taken approximately one week prior to the commencement of the pumping test to collect baseline water quality data for each watercourse. Two samples were taken during the pumping test, one just following the start of the test and one just prior to the completion. Samples taken from the river were immediately placed in a cooler containing ice to ensure that the sample temperature remained below 10 Celsius ( C). The samples were then stored in the AEC office refrigerator, and couriered to AGAT Laboratories (Mississauga, ON) within 48 hours of sampling. AGAT Laboratories is an analytical laboratory accredited by both the Canadian Association for Laboratory Accreditation (CALA) as well as the Standards Council of Canada (SCC). The laboratory analysis included a wide range of inorganic, metals and nutrient parameters, along with analysis of total suspended solids. Field turbidity measurements were also taken using a Hach Turbidimeter (model 2100P) during each field visit, including daily measurements during the 7-day pumping sequence. 4.0 RESULTS AND INTERPRETATION 4.1 Level/Temperature Monitoring Boyce s Creek During the surface water monitoring period between July 18 th and August 16 th, 2013, water levels at Flow 1B station were measured within the range of 0.13 to 0.28 metres. levels at the Flow 2B station were measured within the range of 0.09 to 0.48 metres. levels at the Flow 1B station were generally higher than the water levels at the Flow 2B station during pre- and post-pumping conditions, with the exception of significant storm events. The TRCA examined the maximum flows to Walker Creek and Boyce s Creek and suggested each of these watercourses could sustain discharge flows of up to 9000 L/min. Therefore, a guideline of 9000 L/min was used to assess flooding (at each creek). AZIMUTH ENVIRONMENTAL CONSULTING, INC. 3

8 Judging by the flow data collected, a discharge of 9000 L/min correlates to a water level of approximately 0.35 metres for Boyce s Creek, which was not observed during the 7- day pumping test (maximum observed water level was 0.28 metres). During the surface water monitoring period, water temperature at the Flow 1B station was measured within the range of 9.1 C to 25.6 C. temperature at the Flow 2B station was measured within the range of 9.5 C to 25.2 C. As can be observed in Figure 5, water temperature at the Flow 2B station was generally 1 to 2 C colder than Flow 1B prior to and following the pumping sequence, although this temperature differential reversed during the pumping sequence. This may show that ground water contribution at Flow 2B is higher than at Flow 1B, which created colder water temperatures at the downstream location. The discharge water influenced the creek during the test, which naturally warmed as it flowed downstream from Flow 1B to Flow 2B. On average, the water temperature in Boyce s Creek was lowered 7 C to 10 C during the 7-day pumping test when compared the baseline conditions. level graphs for each of the Boyce s Creek monitoring stations are presented in Figure 2 (all figures presented in Appendix A). temperature graphs for each of the Boyce s Creek monitoring are presented in Figure Walker Creek Within the surface water monitoring period between July 18 th and August 16 th, 2013, water levels at Flow 1W station were measured within the range of 0.00 (this station was essentially dry for the entire baseline monitoring leading up to the aquifer performance test) to 0.15 metres. levels at the Flow 2W station were measured within the range of 0.06 to 0.38 metres. levels at the Flow 2W station were higher than the water levels at the Flow 1W station during the entire monitoring period. It should be noted that the Flow 1W station was not installed in a defined channel of Walker Creek. This discharge point was a low-lying wetland catchment area which eventually drained to the main Walker Creek channel. The TRCA examined the maximum flows to Walker Creek and Boyce s Creek and suggested each of these watercourses could sustain discharge flows of up to 9000 L/min. Therefore, a guideline of 9000 L/min was used to assess flooding (at each creek). Judging by the flow data collected, a discharge of 9000 L/min correlates to a water level AZIMUTH ENVIRONMENTAL CONSULTING, INC. 4

9 of approximately 0.35 metres for Walker Creek, which was not observed during the 7- day pumping test (maximum observed water level was 0.26 metres). During the surface water monitoring period, water temperature at the Flow 1W station was measured within the range of 8.9 C to 16.5 C. temperature at the Flow 2W station was measured within the range of 12.2 C to 27.6 C. As can be observed in Figure 6, water temperature at the Flow 2W (downstream) station was warmer than the Flow 1W (upstream) station, as expected. Discharged water travelled approximately 1 km between the upstream and downstream stations (including through a series of 4 ponds), which explains the differential in water temperature. On average, the water temperature in Walker Creek was lowered 0 C to 6 C during the 7-day pumping test when compared the baseline conditions. No fish species that may be present in Boyce s and Walker Creek are known to spawn during the time of the testing sequence (early to mid August). Therefore, the cooling of water as a result of the discharge water would have had no impact on fish spawning or egg incubation. level graphs for each of the Walker Creek monitoring stations are presented in Figure 3. temperature graphs for each of the Walker Creek monitoring are presented in Figure Stream Flow Monitoring Boyce s Creek During the surface water monitoring period between July 18 th and August 16 th, 2013, stream flow at the Flow 1B station was measured within the range of 0.9 to 45.0 L/s. Stream flow at the Flow 2B station was measured within the range of 0.5 to 59.4 L/s. Baseflow levels were measured within the range of 0.5 to 3.4 L/s, with a peakflow measurement of 59.4 L/s recorded during a significant storm event on August 1 st, With the exception of the significant storm event during baseline monitoring, the discharge from the CE4A pumping increased flow in Boyce s Creek up to approximately 44 times the baseflow amount. Although this amount sounds significant, the creek was able to convey the discharge water without issue because the overall flow was less than the suggested TRCA flow capacity of 9000 L/min. The manual stream flow and water level measurements taken at each Boyce s Creek monitoring station are presented in both tabular (Table 1) and graphical (Figures 7) form.

Stream flow at the Flow 2B station was measured within the range of 0.7 to 58.9 L/s. Baseflow levels were measured within the range of 0.7 to 2.2 L/s, with a peakflow measurement of 58.9 L/s recorded near the beginning of the 7-day pumping test. With the exception of a significant storm event during baseline monitoring, the discharge from the CE4A pumping increased flow in Walker Creek up to approximately 59 times the baseflow amount. Although this amount sounds significant, the creek was able to convey the discharge water without issue because the overall flow was less than the suggested TRCA flow capacity of 9000 L/min. The manual stream flow and water level measurements taken at each Walker Creek monitoring station are presented in both tabular (Table 2) and graphical (Figures 8) form. Figures 8 shows the rating curve which presents and forecasts the relationship between flow and water level at each of the monitoring stations. It should be noted that only a AZIMUTH ENVIRONMENTAL CONSULTING, INC. 6

11 rating curve was created for the Flow 2W station, as the Flow 1W station did not have a defined channel.

One sample was taken approximately one week prior to the commencement of the pumping test to collect baseline water quality data for each watercourse. Two samples were taken during the pumping test, one just following the start of the test and one just prior to completion. Turbidity was also measured at all stations throughout the monitoring period, including daily measurements during the 7-day pumping test. Laboratory analysis showed no significant variance in any water quality parameter when comparing the baseline water quality data to the data from the sampling completed during the pumping test. Prior to the commencement of the 7-day pumping test, a minimum turbidity threshold of 8 NTU s above baseline levels was suggested as a guideline by TRCA staff for Boyce s AZIMUTH ENVIRONMENTAL CONSULTING, INC. 7

12 and Walker Creek. As can be observed in Figure 4, turbidity levels actually improved during the 7-day pumping test when compared to baseline levels. The average turbidity level for all stations during baseline monitoring was 3.3 NTU, and the average turbidity level during the 7-day pumping test was 1.4 NTU. Laboratory analysis reports for all sampling events are presented in Appendix B. 5.0 CONCLUSIONS Based on the surface water monitoring data collected between July 18 th and August 16 th, 2013, it is our opinion that the volume of ground water discharged from the 7-day pumping test for CE4A was not enough to negatively impact water levels, flow or water quality within Boyce s Creek or Walker Creek. The quality and quantity of ground water pumped from CE4A did not have a negative impact on fish species which may have been present in Boyce s and Walker Creek during the pumping sequence, as the temperature and turbidity levels were found to be significantly lower than baseline surface water levels within each creek. Also, no fish species are known to spawn during early to mid August, so the discharge water could not have any negative impact to fish spawning or egg incubation.
