The proposed development property (total) area is approximately 12.92 hectares (ha), as shown on Figure 1. The proposed subdivision is located primarily within the existing settlement boundary for the community of Maryhill, as defined by the Official Plan of the Regional Municipality of Waterloo (see background mapping in Appendix A). The development would extend west from the existing Homestead Drive and Zingervilla Place subdivision. As shown on Figure 1, the development site represents a portion of a land ownership parcel that also extends northward. The entire property (except wetland areas, as discussed later in this report) is currently in agricultural use. The adjacent land use to the immediate north, west and south is agricultural and rural (farm or estate) residential. Residential areas occur east of the site (Homestead Dr. / Zingervilla Pl., and Maryhill Village Heights - St. Boniface Dr. / Mathias Cres.), further southeast of the site (along Maryhill Rd. and main village area), and further south of the site (along St. Charles St.). A cemetery, a Nursing Home facility (Twin Oaks) and a School (St. Boniface Catholic School) are located near the southeast corner of the site, generally between the proposed subdivision and Maryhill Rd. The proposed development would consist of 38 single family residential lots serviced by a Municipal water supply and individual septic systems. 1.2 SCOPE The hydrogeologic assessment was undertaken in support of the Region of Waterloo Draft Plan of Subdivision Application and the Township of Woolwich Zoning By-law Amendment Application. The study scope is intended to address the current Region of Waterloo and Township of Woolwich groundwater related study requirements for the application. This study also provides information relevant to the concurrent Natural Environment assessment undertaken by Aboud and Associates Inc., and forms part of the Environmental Impact Study (EIS) completed to address Region of Waterloo, Township of Woolwich and Grand River Conservation Authority requirements. 1.2.1 Regional Municipality of Waterloo Requirements The Regional Municipality of Waterloo study requirements are outlined in the document: Regional Municipality of Waterloo Guidelines for Hydrogeological Studies for Privately Serviced Developments (May 1991). In addition, pre-consultation meetings were held with the Region to ensure the study approach and level of effort was appropriate. Given that the municipal water supply servicing will ensure an adequate and safe supply of potable water for the proposed development (and as a result there will be no on-site use of groundwater resources), the primary study purpose according to the guidelines is Groundwater Science Corp. 1 Sunset Hills Estates Proposed Subdivision October 4, 2013 to establish: that soil conditions on site are suitable for on-site sewage disposal; and, that on-site sewage disposal will not impair use of the groundwater resource in adjacent areas. This study corresponds to the Stage 1 Study and Stage 2 Septic System Impact Assessment (nitrate loading) as defined in the Regional guidelines. Lot specific testing and detailed septic bed design / lot layout is to be undertaken by others. The general Stage 1 Study and Stage 2 Septic System Impact Assessment information requirements can be summarized as follows: 1. Identification of site location. 2. Data Review, including: a. site setting; b. physiographic region; c. regional geology; and, d. regional hydrogeologic system. 3. Field program, including: a. door to door inventory of water supply wells; b. completion of test-pits and/or shallow boreholes to determine surficial geologic and hydrogeologic conditions; c. water level monitoring; d. grain size analysis and percolation time estimates of representative soil samples; and, e. development and water quality sampling at monitoring wells. 4. Nitrate Impact Assessment and estimate of number of lots which can be accommodated on the property; 5. Reporting. Specific requirements addressed by this report are detailed within the respective report sections dealing with each of the above items. 1.2.2 Township of Woolwich Requirements The Township of Woolwich study requirements are outlined in the (undated) document: Draft Township of Woolwich Guidelines for Hydrogeologic Studies for Proposed Residential Developments. Given that the development will be supplied with water from a municipal supply, the general information requirements can be summarized as follows: 1. Identification of site location. 2. Data Review, including: a. site setting; b. regional and site geology; and, c. regional groundwater system. 3. Field program, including: Groundwater Science Corp. 2 Sunset Hills Estates Proposed Subdivision October 4, 2013 a. door to door inventory of water supply wells; b. monitoring well installation; and, c. water level monitoring program. 4. Terrain analysis and septic system impact analysis; 5. Reporting. 1.2.3 Environmental Impact Assessment As part of the EIS and Functional Servicing Report, information regarding overall hydrology and hydrogeology, including: groundwater conditions at the site; groundwater flow direction; water balance; and, groundwater interaction with surface water features need to be defined. In addition, an impact analysis, including an assessment of potential groundwater level, and water balance impacts, will also be required. This report includes typical EIS information and analysis requirements, such as: an outline of the study methodology a description of the topographic setting, local surface water drainage and natural environment features (including springs, wetlands, etc.); a description of the geologic and hydrogeologic setting (including aquifers, groundwater/surface water interaction, water budget, etc.); a description of the proposed development; an examination of the potential impact of the proposed development (impact assessment); and, conclusions and recommendations. Groundwater Science Corp. 3 Sunset Hills Estates Proposed Subdivision 2.0 October 4, 2013 METHODOLOGY This assessment included a background information review to characterize the site setting, detailed site-specific fieldwork to characterize local conditions and the use of specific analysis methods for the water budget and nitrate impact assessment. Standard hydrogeologic field and analysis methods are used for this study. The specific methodologies used for each step of the characterization and analysis are outlined in the respective Sections of this report. 2.1 INFORMATION REVIEW As part of this study the following information sources were used: 1) Peto MacCallum Limited, December 2012.; Geotechnical Report. 2) Gamsby and Mannerow Limited, October 2013: Functional Servicing Report, Sunset Hills Estates Subdivision, 31 Homestead Drive, Township of Woolwich (Maryhill) and associated engineering drawings. 3) Aboud and Assciates Inc.; October 4, 2013: Sunset Hills Estates, 31 Homestead Drive, Maryhill, Township of Woolwich, Scoped Environmental Impact Study. 4) GSP Group Inc., October 1, 2013: Draft Plan of Subdivision drawing. 5) Stantec Consulting Ltd., December 2005: Water Supply Upgrades and GUIDI Study, Maryhill Village Heights Water Supply System, Regional Municipality of Waterloo. 6) Lake Erie Region Source Protection Committee, August 16, 2012: Grand River Source Protection Area, Approved Assessment Report. 7) Region of Waterloo online interactive mapping website: GIS Locator (http://maps.region.waterloo.on.ca/locator/locator.htm). 8) Grand River Conservation Authority online interactive mapping website: GRIN (http://www.grandriver.ca/index.cfm). 9) Ministry of the Environment (MOE) water well records as available through the online interactive Well Record Data mapping website (http://www.ene.gov.on.ca/environment/en/mapping/wells/). 10) Ontario Base Map (OBM) 1:10,000 series topographic mapping.

Groundwater Science Corp. 4 Sunset Hills Estates Proposed Subdivision 3.0 October 4, 2013 BACKGROUND REVIEW Relevant background mapping and information is included in Appendix A, and includes excerpts from the GUDI and Source Protection study reports. 3.1 SITE SETTING 3.1.1 Subwateshed Setting The general site setting is shown in Figure 2. The overall study area is located within the Central Grand Subwatershed as identified by the GRCA Source Protection Studies (see Appendix A). Based on the detailed topographic mapping available to this study, the development falls primarily within the catchment area of Hopewell Creek. There are no drainage channels located within the proposed development site. The start of the Zettel Municipal Drain (catchbasin and below grade piping flowing eastward) is located near the northeast corner of the development site. The Zettel Municipal Drain consists of approximately 1,478 metres (m) of underground piping/tile and approximately 150 m of open ditch draining to Hopewell Creek. Hopewell Creek is the largest drainage feature in the area, flowing generally northeast to southeast toward the Grand River. The main creek channel is located southeast of Maryhill, approximately 890 m from the site. Based on GRCA mapping, the channel elevation is below 322 metres above mean sea level (mAMSL). An unnamed tributary of the Grand River is mapped as originating with the agricultural fields 170 m or more southwest of the site, at elevations of approximately 340 mAMSL. This tributary is mapped as flowing south across St. Charles St. and then generally southwest. The Maryhill Swamp PSW is located generally west and northwest of the site at a distance of 270 m or more. Based on GRCA topographic mapping, the wetland occurs at an elevation of approximately 338 mAMSL. GRCA mapping also shows a wetland associated with the unnamed tributary south of St. Charles St., occurring generally at an elevation below 330 mAMSL. There are no regionally significant groundwater recharge or discharge areas on-site. In addition, no Well Head Protection Areas (WHPA) extend to, or near, the site. 3.1.2 Site Topography The general topography of the site and area is shown on Figure 2 and Figure 3. More detailed topographic mapping for the site is provided by Gamsby and Mannerow Limited on the Existing Conditions Plan and other engineering drawings. Please refer to those engineering drawings for additional information. The topography at the site is characterized as undulating, consisting of rolling slopes. The existing land surface is generally highest within the west/southwest portion of the site, and lowest within the northeast portion of the site. The current ground elevations across the site range from approximately 350.0 mAMSL to 340.0 mAMSL with an overall slope from southwest to northeast. Existing on-site surface water drainage (catchment) areas are shown on Figure 3. As shown, an enclosed drainage area, with ground surface elevation of approximately 339.5 mAMSL, is located within the portion of the development site immediately south of Homestead Dr. Groundwater Science Corp. 5 Sunset Hills Estates Proposed Subdivision 3.1.3 October 4, 2013 Natural Environment Features and Drainage Natural surface water features on and immediately adjacent to the site include four wetland areas, identified as WE1, WE2, WE3 and WE4, as shown on Figure 3. None of the wetlands identified on-site are considered Provincially Significant Wetland (PSW). The wetland boundaries were defined in the field as part of the Natural Environment assessment (Aboud and Associates Inc.) and surveyed (ACI Survey Consultants Inc.) as part of overall site planning and assessment. Additional information, including site specific field observations and data collected as part of this study, regarding the wetlands is included in Section 4.5 and Section 5 of this report. Wetland WE1 is described in the EIS as a tableland wetland located within a depression. WE1 is classified as duckweed mixed shallow aquatic with components consisting of mineral deciduous swamp and reed-canary grass graminoid mineral meadow marsh. The wetland includes a seasonal pond, however there is no defined channel inlet, or outlet, to this feature. The ground surface elevations within the defined wetland boundary at WE1 range from approximately 339 to 340 mAMSL. Under existing conditions a portion of the on-site drainage (via overland sheetflow from higher elevation lands within the development boundary) is directed toward WE1 (central catchment). Wetland WE2 is described in the EIS as a tableland wetland located within a depression. WE2 is classified as a reed-canary grass graminoid mineral meadow marsh. This feature abuts the northeast corner of the development area (adjacent to Street A). The ground surface elevations within the defined wetland boundary adjacent to the development edge are below approximately 336 mAMSL. Under existing conditions, surface water (overland sheetflow) from a small portion of the northeast corner of the development area is directed toward WE2. Runoff from this wetland is directed to the Zettel Municipal Drain, via the catchbasin inlet (top of grate elevation approximately 336.98 mAMSL). Therefore surface water discharge from WE2 via the drain occurs only during very high water level events. The invert elevation of the below grade piping at the catchbasin is approximately 334.65 mAMSL (e.g. the drain is buried over 1 m below the wetland floor). Wetland WE2 also extends eastward toward Maryhill Road. Wetland WE3 is described in the EIS as a tableland wetland located within a depression. WE3 is classified as a reed-canary grass graminoid mineral meadow marsh. The wetland occupies a small area along the south boundary of the site, with ground surface elevations between 343.5 and 344.5 mAMSL within the defined wetland boundary. There is no defined channel inlet or outlet to this feature. Under existing conditions, surface water (via overland sheetflow) from the southeast corner of the site is directed toward WE3. Although there is no defined channel outlet to this feature, based on the topographic mapping any surface water overflow from WE3 during high water conditions would be directed along the south site boundary toward the enclosed drainage area south of Homestead Dr. (south catchment). Wetland WE4 is described in the EIS as a tableland wetland location within a depression. WE4 is classified as a cattail graminoid mineral meadow marsh with a reed-canary grass graminoid mineral meadow component. The wetland is located at the approximate midpoint of the northwest development boundary. The ground surface elevation within the defined wetland boundary is approximately 339 mAMSL. There is no defined channel to Groundwater Science Corp. 6 Sunset Hills Estates Proposed Subdivision October 4, 2013 this feature. Under existing conditions, surface water (via overland sheetflow) from the northwest portion of the site is directed toward WE4. An agricultural ditch (with seasonal flows northward) originates near the north edge of WE4, approximately 45 metres (m) north of the development area boundary. Surface water overflow from WE4 during spring melt or significant storms would be directed toward the ditch, and flow toward wetland WE2. Sheetflow runoff from a small portion of the site, shown along the southeast boundary in Figure 3, moves eastward off if the property. 3.2 PHYSIOGRAPHY AND GEOLOGIC SETTING The Maryhill area is located within the Physiographic region known as the Guelph Drumlin Field. The drumlin field is developed on a glacial till plain which is intersected by a network of glacial melt spillways (sand and gravel deposits). The drumlins, and the plain upon which they are developed, consist of stoney till. Stream systems in this area, including Hopewell Creek, occupy many of the spillways. The surficial (Quaternary) geology at the site is reported to consist of the silty sand to sandy silt Port Stanley Till and is mapped as having “hummocky” topography. The Breslau Moraine, consisting of the clayey silt Maryhill Till, is mapped at surface to the immediate west of the proposed subdivision and reported at depth in the general area. The clayey silt Catfish Creek Till is also reported to occur at depth. The till units can be considered regional aquitards, limiting groundwater recharge potential where they occur at surface, and vertical groundwater movement (upwards or downwards) where they occur at depth. A thick overburden sequence is reported in the area. Based on a review of water well records, the depth to bedrock in the immediate area of the site (e.g. along Homestead Dr. and Zingervilla Pl.) is over 39 m below ground surface. The underlying bedrock in this area is the Silurian Period dolostone of the Guelph Formation. 3.3 REGIONAL HYDROGEOLOGY Much of the community of Maryhill is serviced via the municipal water supply, including the Maryhill Village Heights development, portions of St Charles St. west of Maryhill Rd., and the development area south of St. Charles St. (Notre Dame Ave, Isley Dr., Halter Ave). The remainder of the community relies on private water supply wells. The entire community relies on individual septic systems. The overburden sequence in the Maryhill Village Heights area has been characterized by the GUDI study as a series of alternating hydrogeologic layers as follows: Aquitard 1 at surface, consisting of silty sand to clayey silt till (Port Stanley Till or Maryhill Till) up to 6 m thick. Shallow dug or bored wells may occur within this unit, particularly within coarser zones of the till deposit. Aquifer 1, consisting of a relatively thin (e.g. between 1 to 6 m thick) sand and gravel unit underlying the surficial till unit(s). This aquifer is of limited extent and may or may not be present. Some shallow wells are completed within this aquifer. Aquitard 2, corresponding to the Maryhill Till and consisting of a clayey silt till deposit. The aquitard thickness is reported to range from approximately 8 to 13 m. Groundwater Science Corp. 7 Sunset Hills Estates Proposed Subdivision October 4, 2013 Aquifer 2, consisting of a glaciofluvial fine sand to gravel ranging in thickness from approximately 5 to 12 m. This aquifer is interpreted to be regionally extensive. A number of drilled wells, including the Municipal supply wells at the Maryhill Village Heights development, are completed in this sand and gravel unit. Aquitard 3, corresponding to the Catfish Creek Till and consisting of a clayey silt till overlying bedrock. This aqitard thickness was reported to be approximately 5 m in this area and provides effective hydraulic barrier between Aquifer 2 and the bedrock system. The Guelph Formation bedrock forms a regionally extensive aquifer system. Many drilled wells in the area are completed in the bedrock unit. Water well records and private water supply status for the immediate area of the site is summarized and discussed in Section 4.1 of this report. Based on regional Source Protection studies, including water balance assessments as part of Tier 3 Studies for the area, recharge rates for the development site been estimated to range from 0.101 to 0.161 m/yr. This recharge rate is relatively low, but is based partially on large-scale topographic and surficial soil mapping, and should be refined based on site specific data. Additional discussion regarding the existing site water balance is provided in Section 5.0. The GUDI study also provides a summary of the regional flow direction within the Municipal water supply aquifer (Aquifer 2). In addition, the Source Protection study provided interpretations of the Watershed scale water table and potentiometic elevations based on water well record data showing regional flow direction which are in relative agreement with the GUDI study. On a regional basis reported groundwater elevations within the deep water supply aquifer(s) vary from approximately 325 mAMSL near Hopewell Creek to 330 mAMSL north of the site. Overall groundwater flow direction is reported to be north to south within the Maryhill area. However, as illustrated by the GUDI study figure (see Appendix A) water level elevations at some (shallow) private wells east of the site have water level elevations at, or near, 340 mAMSL, significantly higher than the potentiometric levels associated with the deeper aquifer systems. Based on the setting, occurrence of surface water features, and, shallow water well record water level elevation data, a local water table system also occurs within the surficial soil units. The shallow flow system may not correspond to the deeper system, and may be based more directly on surface water features that may provide recharge (e.g. the Maryhill Swamp complex northeast of the site) to discharge features or drains (e.g. tributary system along St. Charles St. West and the wetland/Zettel Drain system. In order to characterize the site and provide information relevant to the impact assessment, the shallow soils and water table conditions at the development property were investigated as part of the field program. Groundwater Science Corp. 8 Sunset Hills Estates Proposed Subdivision 4.0 October 4, 2013 FIELD PROGRAM The on-site fieldwork completed for this assessment was undertaken from June 2012 to September 2013. This work included included: site inspections; door to door survey and private well sampling; completion of test pits; drilling and water table monitor installation; response tests at on-site monitoring wells; and, water quality sampling. In addition, water level measurements are ongoing. 4.1 DOOR TO DOOR SURVEY Well locations in the immediate area of the site, as reported by the MOE, are shown in Appendix B. In addition, a summary of well record information is also provided. As noted on the summary and discussed below, four of the reported shallow bored wells near the site are reported to have been replaced by deep drilled wells and are not in use. As illustrated by the water well record database, most of the wells in the area of the site, and within the community, appear to be deep drilled wells completed in Aquifer 2 or the bedrock aquifer. Based on the water well records a 7 shallow bored or dug wells, completed in Aquitard 1 or Aquifer 2, are reported along St. Charles St. West and Maryhill Rd., at distances of 240 m or more south and southeast of the site. A door to door private water well survey was undertaken on May 8, 2013 to provide additional information regarding private water supply. Base on pre-consultation guidance received from the Region, the survey was completed for residences with private water supplies within 500 m of the site. The survey was completed for all residences and businesses within 500 m of the site on: Homestead Dr.; Zingervilla Pl.; Maryhill Rd.; and, St. Charles Street. A total of 76 residences or businesses were visited for the survey. An additional 3 locations were contacted by phone, fax or email. Each residence was visited during business hours, and a survey (information) package was provided. The survey was either completed at that time or if no one was home at that time the survey package was left in the mailbox or at the door. The package included an explanatory letter informing residents of survey, a survey form, and, a self-addressed stamped envelope that could be used to respond. Phone, fax or email response options were also provided. A copy of the survey package, along with a map showing the survey area, and a summary of the responses received, are included in Appendix C. Out of 79 locations surveyed, 20 completed responses were received. In addition, based on conversations with owners (partial response) or observation made (e.g. of drilled well casing in front yard) an indication of the type of well in use was obtained at an additional 18 locations. Based on the responses, the Homestead Dr. / Zingervilla Pl. subdivision appears to be serviced primarily by deeper drilled wells. The location of two shallow dug wells in this area referenced in Appendix B are based on partial responses, therefore no detailed data is available. Based on the survey, 9 shallow (dug, bored or sand point) wells are reported along St. Charles St. West and Maryhill Rd., at distances of 220 mm or more south and southeast of the site. One shallow dug well is also reported on Maryhill Rd. east of the site (and east of the cemetery). However the primary private water supply source in the community appears to be deeper drilled wells. Anecdotally a pattern emerged of well replacement (home owners drilling new deep wells to replace shallow wells) due to water shortages. Groundwater Science Corp. 9 Sunset Hills Estates Proposed Subdivision October 4, 2013 The shortages were sometimes attributed by the well owners to historical development or water taking activities within Maryhill. Water quality sampling was undertaken on September 3, 2013 at 7 private well locations, including 3 shallow (dug or bored) wells and 4 deep drilled wells distributed within the survey area. Attempts were made to sample all of the wells for respondents within the Homestead Dr. / Zingervilla Pl. subdivision, however not all respondents were interested in participating. The sample results are summarized in Appendix C. Each participating resident received a copy of the water quality results for their well. 4.2 TEST PITS A total of 7 test-pits were completed within the proposed development area on June 25, 2012. The test pit locations are shown on Figure 4. Selected soil samples were submitted to Peto MacCallum Limited for grain size analysis and percolation rate estimates. Test pit logs and grain size analysis results are provided in Appendix D. In general the test pits indicate that the upper soils over much of the central (higher elevation) portion of the site (TP3 to TP7) consist of sand and/or gravel, to depths of over 3.0 m. Within the eastern (lower elevation) portion of the site (TP1 and TP2) a 1.0 m thick fine sand layer was encountered at surface and a sandy silt till occurred at depth. Based on the test pit grain size analysis results, the fine sand and silty sand and gravel units have an estimated percolation rate of 15 min/cm. The Sand and gravel unit has an estimated percolation rate of 4 to 12 min/cm. 4.3 BOREHOLE DRILLING AND MONITOR INSTALLATION The borehole drilling and monitoring well installation program was completed by Peto MacCallum Limited as part of the geotechnical study for the site. A total of 5 boreholes were completed and 4 water table monitoring wells (BH2 to BH5) installed in November 2012. The borehole locations are shown on Figure 4. Copies of the reported borehole logs are included in Appendix D. The monitoring wells are reported to consist of 2-inch diameter PVC pipe and slotted screens. The wells were installed through the augers to the desired depth, and a silica sand-pack placed over the screened interval. The remainder of the annual space was sealed with bentonite. In order to assess conditions at the wetland areas on-site three drive-point piezometers (DP1, DP2 and DP3) were also installed in November 2012. The drive-point locations are shown on Figure 4. The piezometer were installed by hand and consisted of 0.3 m long nominal 2 cm (0.75 inch) diameter manufactured screened drive-point and diameter galvanized pipe riser. The wells and drive-point were developed in November 2012 by pumping (using dedicated Waterra® inertial pumps) until the discharge water was relatively clear and/or a steady water level response was noted. Elevation data for the monitors was obtained as part of detailed site survey and mapping completed for the development. Installation elevations are summarized in Table 1.

The measurements were obtained as depth to water below top of well casing using a Heron Instruments® electronic water level tape and recorded in the field. The measured water table elevations at monitoring well locations are summarized in Table 2. A hydrograph of the monitoring data is shown in Figure 5. Water level monitoring is on-going at the site.

Values noted as n/a are not available (not yet installed or inaccessible). Note that when DP1 was installed only 0.18 m of water was present, however the drive Groundwater Science Corp. 11 Sunset Hills Estates Proposed Subdivision October 4, 2013 point was inaccessible from April to June due to high pond levels (up to 1.2 m of water). Overall climate conditions in 2013 were relatively “wet”, resulting in above average surface and groundwater conditions. Additional interpretation of the observed water level data is provided in Section 5. 4.5 RESPONSE TESTS Response tests were completed at each of the monitoring wells to estimate the hydraulic conductivity (K) of the soils within the water table. The tests were completed on February 21, 2013 using a solid volume slug and dataloggers set to a 1 second sampling frequency as rising or falling head (slug) tests. The response data was analyzed according to the Bouwer and Rice method using the AQTESOLV® computer analysis program. The test analysis plots are included in Appendix E. The response test analysis is summarized as follows: Location BH2 BH3 BH4 BH5 K Estimate (m/s) Falling Head Rising Head 3.78E-06 2.57E-06 1.19E-04 4.40E-05 3.80E-05 5.41E-05 1.10E-05 8.30E-06 geometric mean value: 1.768E-05 m/s Table 3: Response Test Analysis Summary 4.6 ON-SITE WATER QUALITY SAMPLING Two sets of groundwater quality samples were obtained at the on-site monitoring wells as part of this study. Wet season samples were obtained on February 21, 2013, and dry season samples were obtained on September 3, 2013. Samples were obtained using a dedicated Waterra® inertial pump at each location. Each well was purged (approx. 5 or more bore-volumes) to a relatively sand-free state prior to sampling. The samples were kept cool and submitted to ALS Laboratory Group (Waterloo) for analysis within 8 hours. The on-site water quality analysis lab reports are included in Appendix F. The nitrate results are summarized in Table 4.

As noted in the GUDI and Source Protection studies, and confirmed through the private water well record review and survey, the primary water supply aquifers in the area are located at depth (Aquifer 2 and/or bedrock system). The overall groundwater flow in the deep aquifer system is north to south. These deep aquifers are isolated from the shallow system (surface water, Aquitard 1 and Aquifer 1) by the overlying till unit(s). The proposed Sunset Hills Estates subdivision will be supplied by Municipal water, therefore will not include any additional water supply well drilling or water taking on-site. Therefore no water supply analysis is required and no water level (drawdown) pumping effects will be associated with the proposal. In addition, the shallow water table system at the proposed Sunset Hills Estates subdivision can be considered hydraulically isolated from the deeper water supply aquifer systems (and most water supplies in the area). This assessment therefore focuses on water table conditions, groundwater-surface water interaction, and, potential impacts to this system on-site and in the surrounding area. In order to visualize groundwater conditions at the site, a series of cross-sections have been prepared based on the detailed topographic mapping, water well records, test pit results, borehole drilling results and water level monitoring. The section locations are shown on Figure 6 and the sections are included as Figure 7 and Figure 8. As illustrated by the sections, on-site testing indicates that the central ridge (and higher elevation lands) on-site consist of sand and gravel at surface overlying silt till. The silt till occurs at surface over the remainder of site. Based on water well records for deep wells adjacent to the site, the till sequence (corresponding to Aquitard 2) has a thickness of 20 m or more below the site. The shallow overburden aquifer (Aquifer 1) and/or deep overburden aquifer (Aquifer 2) is not always present or reported on the water well records. The monitoring results indicates that at the monitoring locations the water table occurs within the till unit on-site. Water table contour maps showing high and low water table conditions respectively are presented in Figure 9 and Figure 10. Based on the water table mapping overall groundwater flow at the site is from south to north, with some groundwater flowing on-site from upgradient lands. The shallow groundwater flow system appears to exit the site at the north corner, flowing toward WE2 and eventually to the Zettel Municipal Drain. Based on the setting, shallow groundwater flow from fields west and north of WE2 are also expected to converge at this wetland and enter the drain. Reported static water levels for shallow wells within the Homestead Dr. / Zingervilla Pl. subdivision indicate that the groundwater table within the subdivision is expected to be higher than observed groundwater levels near WE1. Therefore some groundwater flow from the existing subdivision area is also expected to be toward the site and toward WE2. The water level monitoring results also indicate that feature WE1 is a recharge area, with surface water levels consistently higher than surrounding groundwater levels (at DP1, BH3 and BH4). In addition, when the feature is dry the pond bottom is observed to have Groundwater Science Corp. 13 Sunset Hills Estates Proposed Subdivision October 4, 2013 a thick organic layer overlying clay. This feature captures on-site surface water runoff, stores this water and slowly recharges the downgradient groundwater system. No surface water outflow from WE1 was noted over the monitoring period. Pond levels within WE1 would need to exceed 340 mAMSL in order for outflow to occur. As the pond approaches 340 mAMLS the water surface would rise above the basal muck/clay layer and reach the surrounding sand/gravel/till units, where water can infiltrate more rapidly. This may be the reason no pond outflow is observed or reported. Although the shallow groundwater flow system appears to converge at WE2, no identifiable discharge is observed within the wetland, and, vertical gradients at DP3 are small in magnitude. The Zettel Municipal Drain may intercept the water table within the wetland and drain this area. The water table remains close to surface over much of the year and likely helps to maintain moisture conditions within the wetland soils. Surface water inputs from the surrounding area are also likely important for maintaining the seasonal wetland hydroperiod. Given conditions at WE2, the wetland does not have a significant recharge function. Based on the water level elevations observed at BH2, the water table remains close to surface over much of the year and serves to maintain the moisture regime within the soils at WE3. No groundwater discharge areas were identified within WE3. This feature likely relies on a combination of surface water inflows during the wet (spring) and water table inputs to the soil regime in dry (summer/fall) conditions. Surface water outflow was observed from WE3 during snowmelt conditions in the spring of 2013 (only), however no outflow was noted over the remainder of the monitoring period. Given the conditions at WE3, some minor recharge could be expected related to the expected occasional inflow and retention of surface water, however this recharge would not be significant in volume to the overall groundwater system. Based on the water level elevations observed at DP2, the water table also serves to maintain the moisture regime within the soils at WE4. No groundwater discharge areas were identified within WE4. This feature likely also relies on a combination of surface water inflows during the wet (spring) and water table inputs to the soil regime below surface in dry (summer/fall) conditions. No surface water outflows were noted from WE4 over the monitoring period, however could be expected under some spring snowmelt or heavy rainfall events. Given the conditions at WE4, some minor recharge could be expected related to the occasional inflow and retention of surface water, however this recharge would not be significant in volume to the overall groundwater system. The ditch north of WE4 has been excavated into the local landscape (i.e. is lower in elevation than WE4 or agricultural fields on either side). The ditch was observed to have flow (interpreted to be groundwater discharge) at the February 2013 monitoring event (only). However the ditch is observed to be dry much of the year. As the water table rises in the surrounding area seasonal discharge may occur along the base of the ditch. Groundwater Science Corp. 14 Sunset Hills Estates Proposed Subdivision 6.0 October 4, 2013 PROPOSED DEVELOPMENT For specific details regarding the development plan, please refer to descriptions and drawings provided by GSP Group Inc. and Gamsby and Mannerow Limited. The following is a general summary of the plan for the purposes of assessing potential development related groundwater impacts. The proposed development would consist of 38 estate residential lots serviced with a Municipal Water Supply and individual septic systems. The general lot layout is shown in Figure 11. Based on the Geotechnical Investigation, it is expected the septic systems will be designed at a minimum as conventional class four (4) treatment systems. Tertiary treatment systems are also being considered to provide an additional attenuation of potential impacts and reduce potential septic bed size to allow for backyard amenities (e.g. pools, etc.). Lot level testing and septic system / bed design is to be prepared at a later date. Stormwater quantity and quality controls are proposed for the site as outlined in the Functional Servicing Report (Gamsby and Mannerow Limited). Lot level controls, consisting of roof leader discharge to lawns and rear yard swales, will assist in maintaining overall groundwater recharge rates at the site. Foundation drainage is to be provided using sump pumps routed to rear or side yards to promote infiltration. High water table elevations have been defined at the site, which will allow foundations and foundation drains to be set at appropriate levels in order to avoid interference with the water table. It is not anticipated that services (or service trenches) will be placed below the water table. If the water table is encountered, appropriate controls such as anti-seepage (or cutoff) collars are recommended to minimize potential impacts. Groundwater Science Corp. 15 Sunset Hills Estates Proposed Subdivision 8.0 POTENTIAL IMPACTS 8.1 WATER BALANCE ASSESSMENT October 4, 2013 In order to estimate the existing water balance components, including groundwater recharge rates, based on site-specific information a water balance assessment was completed. The water balance calculations are included in Appendix G. The water balance for the site has been developed in accordance with MOE development application guidelines for estimating evapotranspiration (Hydrogeological Technical Information Requirements for Land Development Applications, April 1995). A Thornthwaite and Mather analysis was completed using monthly precipitation and temperature climate normals (1981 to 2002) as reported by Environment Canada for the Waterloo Wellington Airport Weather Station. The analysis provided an estimate for actual evapotranspiration within the proposed development area. Annual average precipitation is estimated to be 916.48 mm/yr, and actual evapotranspiration is estimated to be 570.71 mm/yr. In addition, a free water surface (wetland pond) evaporation rate of 692.79 mm/yr is estimated based on calculated values reported by United States Department of Commerce National Oceanic and Atmospheric Administration (NOAA) for Lake Ontario for the same long-term normal period (1981 to 2002), as reported in: Great Lakes Monthly Hydrologic Data, NOAA Data Reports GLERL-26 (1983) and GLERL (1993). As noted previously, under existing conditions much of the runoff on-site is captured and infiltrated wither within feature WE1 or within the infiltration area shown on Figure 3. The total area of enclosed drainage on-site is estimated to be approximately 9 ha, and within this catchment a pond (WE1) with a maximum area of 0.73 ha occurs. Within the enclosed drainage area of the site there is no runoff (exiting the site) and the total infiltration recharge volume is calculated as the difference between the precipitation volume and evapotraspiration (within vegetated or cropped areas) and evaporation from the pond surface. Total annual recharge within this area is estimated to be 26,095 m3/yr. Runoff from the remaining area of the site has the ability to exit the site. Based on an MOE infiltration factor of 0.5 (rolling topography, medium clay loam and cultivated lands), approximately 6,773 m3/yr is estimated to infiltrate within this area each year. Similarly a total annual runoff volume of 6,773 m3/yr is expected to leave the site. Based on the calculations, the total site recharge volume at the site is estimated to be 32,868 m3/yr under existing conditions. The equivalent recharge rate is 0.27 m/yr. Although this rate is higher than estimated by the Source Protection study water balance modeling, it is reasonable given the (unanticipated) occurrence of sand and gravel over much of the site and the fact that the majority of the site forms an enclosed drainage area. The proposed stormwater controls have been designed to recreate existing surface water catchments and runoff volume to WE1 and WE2. The overall stormwater management plan should also maintain the existing recharge site rate within open vegetated areas (e.g. non-impervious areas). The development impact on site recharge is estimated based on total impervious area created. The FSR indicates that the development will create approximately 3.33 ha of Groundwater Science Corp. 16 Sunset Hills Estates Proposed Subdivision October 4, 2013 impervious area (roofs, driveways, sidewalks and roads). Although some of this water should have the opportunity to infiltrate (in backyard areas or swales, or at the stormwater management ponds), on a conservative basis it is assumed for the impact analysis that impervious area runoff does not infiltrate. Assuming a 3.33 ha reduction in infiltration area, the total site recharge could decrease by 7,204 m3/yr (22% reduction). There are no downgradient receptors that rely on groundwater discharge (e.g. upwells or springs, etc.) therefore the potential reduction in recharge has no significant impact on groundwater resources in the area. Note that since the existing groundwater flow system moves toward WE2 and the Zettel Drain, that the reduction in recharge does not represent a loss of water to these features. Water that would otherwise have infiltrated will enter the stormwater management system and be conveyed to WE1 and WE2. In addition, the site represents only a portion of the overall groundwater catchment that supplies water to WE2 and the Zettel Drain. As noted in Section 8.2, groundwater flow to WE2 within the ownership parcel north of the subdivision alone contributes approximately 1.7 times the recharge volume that currently occurs within the subdivision lands. The reduced infiltration does have implications regarding the nitrate loading assessment, as discussed in Section 8.2. 8.2 NITRATE LOADING ASSESSMENT The proposed use of septic systems at the site will add nitrate to the local shallow groundwater system. The underlying deeper aquifer systems are isolated from the shallow system by the presence of the thick till sequence, which limits vertical groundwater flow and promotes horizontal flow. Groundwater within the shallow (water table) flow system moves onto the site from upgradient lands, through the site from south to north, and then primarily toward feature WE2 and the Zettel Municipal Drain. Shallow groundwater flow from other surrounding lands, in including approximately 21.06 ha owned by the proponent north of the proposed development site, also converges on WE1. Based on the reported static levels within dug or bored wells within the Homestead Dr. / Zingevilla Pl. subdivision, shallow groundwater flow from this area to WE1 and WE2. Shallow groundwater flow from the BH5 area likely moves toward (and below) WE1. Therefore primary groundwater flow from the proposed Sunset Hills Estates subdivision is not toward local drinking water supply wells. We note that the proposed Sunset Hills Estates subdivision will have essentially the same lot size as most of the existing development in this area. Based on the groundwater sampling / monitoring completed as part of the private well survey, existing nitrate attenuation within the surrounding lands and in this geologic setting appears to be sufficient to reduce nitrate-N concentrations due to the existing septic bed nitrate loading in the area to below the drinking water limit. Water potablility problems related to the presence of bacteria have been reported (e.g. by homeowners responding to the well survey), however these issues will be related primarily to well construction and location relative to adjacent septic systems, not due to lot sizing or use of septic systems as a servicing option. Therefore it can be expected that nitrate attenuation within the proposed Sunset Hills Estates Subdivision will create no additional detrimental effects. Groundwater Science Corp. 17 Sunset Hills Estates Proposed Subdivision October 4, 2013 Although monitoring data indicates that natural nitrate attenuation in this setting appears to reduce nitrate loading from the proposed approximate average 0.2 ha lot size to below drinking water limits; deep water supply aquifers are isolated from the potential nitrate loading associated with the proposed development; and, site specific investigations indicate that potential nitrate impacts are expected to flow within the shallow system primarily toward the wetlands and municipal drain (and not toward local private wells), a nitrate attenuation analysis has been completed to confirm nitrate within the downgradient shallow flow sytem will remain below the current Ontario drinking water standard in Ontario for nitrate of 10 mg/L. The nitrate loading analysis takes the form of a mass balance calculation. The assumptions used in the following analysis is based on pre-consultation with the Region. Calculation summaries are provided in Appendix G. Upgradient lands are outside of the settlement boundary, and are not expected to be developed in the foreseeable future. Based on the minimum observed gradient (low water table conditions) of 0.026 between BH2 and BH5; upgradient flow boundary 350 m long; aquifer thickness of 9.4 m (saturated flow thickness at BH2 above the Zettel Municipal Drain elevation); and, an estimated soil K of approximately 1.77 x 10-5 m/s for the till unit, approximately 110,720 L/d flows onto the site within the shallow system. This water is expected to move to wetland WE2 and the Zettel Municipal Drain. The total nitrate mass loading for the site is calculated using the standard 40 mg/L nitrateN septic effluent concentration and 1,000 L/d/lot septic volume. With 38 lots proposed, the total septic nitrate mass at the site is estimated to be 1,520,000 mg/day. Based on an average nitrate-N concentration of 3.2 mg/L within the groundwater flowing on-site an additional nitrate mass of 354,306 mg/day enters the site. Attenuation (dilution) is estimated using the estimated on-site post development recharge of 70,313 L/day (accounting for impervious area), 38,000 L/day of municipal water via the septic beds, and, 110,720 L/day groundwater flow onto the site. Total water volume mixing with the nitrate mass is 219,034 L/day. The resulting average nitrate-N concentration at the downgradient site boundary is calculated to be 8.6 mg/L. For comparison, if 10 lots (approx. 25%) utilize tertiary treatment achieving an effluent nitrate-N concentration of 10 mg/L to allow for backyard amenities (through reduced septic bed sizing), a nitrate-N concentration of 7.2 mg/L is achieved at the site boundary. Allowing for expected groundwater flow from owned lands north of WE2 toward the Zettel Municipal Drain (aquifer width 420 m, thickness of 9.4 m, assuming similar gradient and K values results in total groundwater flow volume of 155,009 L/d with a nitrate-N concentration of 3.2 mg/L), and mixing at drain, final nitrate-N concentration at WE2 and the drain would be approximately 5.5 mg/L. The assessment is conservative in that it examines only the local shallow flow system from the site that contributes to wetland and drain system. Including the surrounding shallow flow system and/or potential intermediate to regional flow systems (and volumes) would reduce the nitrate-N concentration further. The assessment also includes no allowance for denitrification. Given the setting, including recharge conditions at WE1 and likely anaerobic carbon rich environment both below WE1 and at WE2, significant denitrification can also be expected prior to reaching the wetland or drain. Groundwater Science Corp. 18 Sunset Hills Estates Proposed Subdivision 8.3 October 4, 2013 MONITORING PLAN Based on the analysis, no significant groundwater impacts are projected at the site. However, in order to ensure impacts do not occur, a basic groundwater monitoring program is recommended, as follows: 1. Water level measurements shall be obtained at the existing on-site monitoring locations(as accessible) on a quarterly basis, and water quality samples obtained on an annual basis during the first three years after site build-out. 2. At the end of three years of monitoring the data shall be summarized in a report provided to the Region of Waterloo, Township of Woolwich and Grand River Conservation Authority. The monitoring program shall be discontinued if no groundwater impacts are observed after 3 years.

Dear Resident: Groundwater Science Corp. is completing a baseline survey of private water wells in the area of a proposed new residential subdivision on behalf of Sunset Hills Estates. The development property is located within Part Lot 80, German Company Tract, Township of Woolwich, Regional Municipality of Waterloo. The development site is east of Homestead Drive and Zingervilla Place. The subdivision would be within the existing Maryhill settlement boundary as defined by the Township of Woolwich Official Plan. The baseline private water well survey includes properties along Homestead Drive, Zingervilla Place, Maryhill Road, St. Charles Street East and St. Charles Street West. Your residence is in the survey area. The baseline survey is being completed according to technical standards for development studies that are set by the Township of Woolwich and Region of Waterloo. The survey includes the completion of a water well information form to assist in identifying local water well locations, construction, depth, etc. The results will be considered within the technical assessments prepared for the proposed development and will provide baseline (pre-construction) information for the area. Participation in the private water well survey program is voluntary; this letter is to inform you of the survey and to request your participation. A representative of Groundwater Science Corp. will be going door-to-door this week during business hours to complete the survey. A copy of this letter will be provided to each residence in the survey area. If no one is at home at the time of the survey, the survey package will be left in the mailbox or at the door. Attached to this letter is a survey response form. If you are interested in participating please complete and return the survey form (only) in the self-addressed stamped envelope. Completed forms can also be sent by FAX to our office at 519-884-5996. If you have any questions or require assistance with the survey form, please call Andrew Pentney at 519-746-6916 (Waterloo). We would like to have the survey completed by May 24, 2013. Thank-you in advance for your consideration in this matter. Sincerely, Andrew Pentney, P.Geo. Hydrogeologist.
