Box 189 Kemptville, Ontario K0G 1J0 FAX: (613) April 2, Ontario Ltd. 146 Tartan Drive Ottawa, Ontario K2J 3X2 Attention: Mr. Samir Hadziresic RE: WELL EVALUATION EXISTING SUPPLY WELL PROPOSED COMMERCIAL DEVELOPMENT 1358 COKER STREET, OSGOODE WARD CITY OF OTTAWA, ONTARIO Dear Sirs: This letter presents the results of an evaluation of the water quality and quantity for the well that will supply water for the above noted proposed commercial development at 1358 Coker Street in the City of Ottawa, Ontario (see Figure 1 for location). It is understood that the proposed commercial development is to consist of a construction company office and storage building. The well in question was constructed by Air Rock Drilling Company of Richmond, Ontario on March 11, A Ministry of the Environment Well Record for the subject well (TW1) and the Certificate of Well Compliance, provided by the well driller, are provided as Attachment A. A pumping test was carried out at the well, TW1, by a member of our engineering staff on March 19, The testing consisted of a 6 hour duration constant discharge rate pumping test. During the pumping test, water level measurements were made on a regular basis to monitor the drawdown of the water level in the well in response to pumping. Groundwater samples were collected from TW1 at about hour 3 and at hour 6 of the pumping test to characterize groundwater quality. After the pumping period, the pump was shut off and the recovery of the water level in the well was monitored for a period of time. Groundwater Supply Evaluation The well was pumped for six hours at a pumping rate of about 45 litres per minute. Over the course of the pumping test, the water level in the well dropped some 3.4 metres. At the end of the pumping test, 95 percent recovery of the total drawdown in the static water level created during pumping occurred within 38 minutes. Professional Engineers Ontario Authorized by the Association of Professional Engineers of Ontario to offer professional engineering services.

3 Hydrogeological Investigation Ontario Ltd Coker Street, Ottawa, Ontario April 2, The pumping test drawdown and recovery data and plots for TW1 are shown in Attachment B. The drawdown and recovery data provided were measured with reference to the top of the well casing at the test well location. The pumping test data for the test well was analyzed using the method of Cooper and Jacob (1946). Although the assumptions on which these equations are based are not strictly met, this method provides a reasonable estimate of the aquifer transmissivity. Transmissivity was calculated using the following relationship: T 2.3Q 4 ds where Q is the pump rate, m 3 /day ds is the change in drawdown over one time log cycle, m T is the transmissivity, m 2 /day Based on the pumping test drawdown data the transmissivity of the aquifer is estimated to be about 470 m 2 /day. Based on the recovery data the aquifer transmissivity is estimated to be about 26 m 2 /day. The average transmissivity of the bedrock aquifer in the area of the test well is estimated to be about 250 m 2 /day. It is understood that the maximum expected water demand of the proposed development, based on the design capacity for the proposed septic system, is 4835 litres per day. The available drawdown at the well, calculated as the depth of water in the water column, is indicated to be about 55 metres. Over the course of six hours, the water level dropped some 3.4 metres. At the end of pumping, approximately six percent of the amount of available drawdown was used. It is considered that the well is capable of supplying adequate quantity of water for the proposed use. Water Quality To determine the water quality of the groundwater supply, groundwater samples were obtained from the well during the pumping test and prepared/preserved in the field using appropriate techniques and submitted to Exova Accutest Laboratories Ltd. in Ottawa, Ontario for the chemical, physical and bacteriological analyses listed in the Ministry of the Environment (MOE) guideline entitled Procedure D-5-5, Technical Guideline for Private Wells: Water Supply Assessment, August The temperature, conductivity, ph, total dissolved solids, turbidity and residual chlorine levels of the groundwater were measured and qualitative observations of the taste, odour and colour of the groundwater were made at periodic intervals during the pumping test. The results of the chemical, physical and bacteriological analyses of the water samples obtained from the test well and the field water quality are provided as Attachment C and Table I, respectively. The water quality as determined from the results of the analyses is favourable. The water meets all the Ontario Drinking Water Standards (ODWS) health and aesthetic parameters tested for at the test wells except for aesthetic objective for hardness. The water is considered to be hard by water treatment standards. Water with hardness above 80 to 100 milligrams per litre as CaC0 3 is often softened for domestic use. The hardness at the well is 280 milligrams per litre. Water softening by conventional sodium ion exchange may introduce relatively high concentrations of sodium into the drinking water, which may contribute a significant Civil Geotechnical Structural Environmental Hydrogeology

Where ion exchange water softeners are used, a separate unsoftened water supply could be used for drinking and culinary purposes. The lab based turbidity measurement for the water sample obtained after six hours of pumping was 1.6 NTU, which exceeds the health related objective for turbidity but is within the aesthetic objective of 5 NTU. The turbidity was measured in the field to be 0 NTU after six hours. It is considered that the lab measured turbidity was slightly elevated due to the presence of iron and manganese, which were 0.26 and 0.02 milligrams per litre, respectively, after six hours of pumping. Iron may precipitate in the water sample between the time of sampling and the time of testing in the laboratory. No bacteria presence was detected in the water sample obtained after six hours of pumping. Consequently, the noted lab measured turbidity is not considered to be of aesthetic or health related concern. Wellhead Protection The supply well is located within the east portion of the site, while the location of the proposed septic system is within the north portion of the site, some 30 metres distance from the well location. The well casing was observed to extend about 600 millimetres above grade. The well has been properly grouted and cased to a depth of about 15.8 metres below the existing ground surface. Consequently, it is considered that an adequate amount of wellhead protection is in place to protect the water supply for the proposed commercial development. Recommendations for wellhead protection include ensuring that potential contaminant sources are at least 15 metres and preferably at least 30 metres or more from the well. Possible contaminant sources include; chemical storage, garage and related chemicals, such as antifreeze, gasoline, oils, vehicle/boat/equipment storage, sewer lines, septic systems, animal enclosures, manure or compost piles. Avoid activities which may cause spillage into the soil, such as car repair and machinery maintenance. Recommendations for well maintenance include; inspect wellhead annually to ensure that the casing is structurally sound, verify well cap is sealed and that surface water is not pooling around wellhead. To protect the well from physical damage, a small structure or fence should be constructed around it, ensuring easy access for well maintenance/repairs. A lock on the well cap is useful to prevent vandalism. Civil Geotechnical Structural Environmental Hydrogeology
