1 Replacement of Well No. 2 Schedule B Class Environmental Assessment Public Information Centre Information Handout Overview The Region of Peel has identified the need to provide a new municipal well to service the Village of Inglewood within the Town of Caledon and allow for the abandonment of Well #2. Project Objective Investigate alternative solutions and methods to provide a new municipal well for the Village of Inglewood to replace an existing municipal well (Well #2). Through this project, the Region has the opportunity to improve system reliability and security of supply for the Village of Inglewood. Source Water Protection at Inglewood Well No. 2 Potential threats to drinking water identified for the Inglewood Well No. 2 source protection area refer to the following: Residential septic systems Municipal land uses: o Storm water management pond o Wastewater (sewer) system o Wastewater (sewage) treatment plant Agricultural land uses related to the presence of a farm, and Fuel storage Long List of Options Long List of Options Alternative A Do Nothing Alternative B - System Capacity Reduction Alternative C Implement Water Conservation Measures Alternative D - Construct a New Municipal Well Supply Alternative E - Extend Lake-Based Water Supply Alternative F - Increase Capacity of Existing Well Taken forward to shortlist? No Does not address the identified Problem Statement. Well #2 is not a viable long-term supply. No Does not address the identified Problem Statement. Existing level of service and security of supply cannot be maintained. No Peel has implemented a comprehensive program of water conservation program. This is considered to form part of all alternatives. Yes Providing a new production well with sufficient sustainable yield to replace Well #2 will address the Problem Statement. No This alternative is not permitted under current legislation (i.e. Greenbelt Act, 2005). No Does not address the identified Problem Statement. Existing level of service and security of supply cannot be maintained. Page 1

2 Replacement of Well No. 2 Schedule B Class Environmental Assessment Public Information Centre Information Handout Groundwater Exploration Program: Focus of the groundwater exploration program was to examine the buried bedrock valley aquifer complex in the vicinity of the Village of Inglewood and to establish two (2) high yielding deep test wells. A total of nine (9) potentially viable test well sites were identified and prioritized for drilling. A total of five (5) test holes were drilled until two (2) viable test holes were located: Three (3) test holes (Sites B, C & H) failed to identify sufficient coarse grained overburden deposits to warrant the construction of test wells. Two (2) test holes (Sites K & N) were successful in encountering sufficient coarse grained overburden (deep aquifer) deposits that warranted the construction of test Site N (Alternative D1): Test Well N-2014 (TWN-14): TWN-14 was drilled on the south side of the Ken Whillans Resource Management Area north service entrance, approximate 50 metres west of Highway #10 Completed to a depth of 58.5 metres below ground level Tested capacity of 2,304 m 3 /day, Concluded to be Non-GUDI Treatment required for iron levels above the Ontario Drinking Water Standards (Aesthetic Objective) Site K (Alternative D2): Test Well K-2015 (TWK-15): TWK-15 was drilled on the east side of the Cedar Road, approximate 10 metres north of the Forks of the Credit Road Completed to a depth of 64.0 metres below ground level Tested capacity of 1,440 m 3 /day Concluded to be Non-GUDI, Treatment required for iron levels above the Ontario Drinking Water Standards (Aesthetic Objective) Evaluation Criteria Water Supply Sustainable Capacity Water Quality Groundwater Influence Surface Water Influence Economic Costs Relating to Operations & Maintenance and Infrastructure Property Acquisition Technical Constructability Maximize Use of Existing Infrastructure Reliability Social Environment and Land Use Socio-Economic Archeological and Cultural Heritage Agricultural Policies and Legislation Oak Ridges Moraine and Greenbelt Niagara Escarpment Commission Source Water Protection Natural Environment ANSI and ESA/Core Areas Wetlands and Watercourses Species at Risk Page 2

6 Problem and Opportunity Statements Problem Statement The Region of Peel has identified the need to provide a new municipal well to service the Village of Inglewood within the Town of Caledon and allow for the abandonment of Well #2. Project Objective Investigate alternative solutions and methods to provide a new municipal well for the Village of Inglewood to replace an existing municipal well (Well #2). Through this project, the Region has the opportunity to improve system reliability and security of supply for the Village of Inglewood.

7 Class EA Process Overview & Study Area WE ARE HERE Not Required for Schedule B Project This project is being conducted as a Schedule B Municipal Class EA.

8 Background Information The Village of Inglewood is serviced by two existing municipal groundwater production wells (Inglewood Well #2, Inglewood Well #3) each rated at 1,295 m 3 /day. Well #2 was constructed in 1978 and is a shallow well (9.4m Deep) that is considered to be groundwater under the direct influence of surface water (GUDI). It is located adjacent to the Credit River. Well #3 was constructed in 1995 and is a deep well (54.7m deep) that is considered to be groundwater (Non-GUDI). It is located on Highway 10 adjacent to Ken Whillans Resource Management Area. Due to a variety of concerns/issues associated with the potential long-term viability of Well #2 including Source Water Protection requirements, Well #2 has been identified for replacement/abandonment.

9 Long List of Alternatives Alternative Alternative A - Do Nothing Alternative B - System Capacity Reduction Alternative C - Implement Water Conservation Measures Alternative D - Construct a New Municipal Well Supply Alternative E - Extend Lake-based Water Supply Alternative F Increase Capacity of Existing Well Description Continue with existing operations ( Baseline alternative with Well #2 in service). Abandon Well #2 without constructing a new municipal well. Reduce system demands and water supply (well capacity) requirements through water use conservation. Construct a new municipal well with sufficient capacity to replace existing Well #2. Construct a new transmission main from the existing lake-based water supply to Inglewood. Increase Capacity of Well #3 without constructing a new municipal well.

10 Preliminary Screening Short-List Screening Criteria: Can the long-list alternative satisfactorily address the identified Problem Statement Long-List Alternatives Satisfy Screening Criteria Alternative A Do Nothing No Does not address the identified Problem Statement. Well #2 is not a viable long-term supply. Alternative B - System Capacity No Does not address the identified Problem Statement. Existing Reduction level of service and security of supply cannot be maintained. Alternative C Implement Water Conservation Measures Alternative D - Construct a New Municipal Well Supply Alternative E - Extend Lake-Based Water Supply Alternative F - Increase Capacity of Existing Well No Peel has implemented a comprehensive program of water conservation program. This is considered to form part of all alternatives. Yes Providing a new production well with sufficient sustainable yield to replace Well #2 will address the Problem Statement. No This alternative is not permitted under current legislation (i.e. Greenbelt Act, 2005). No Does not address the identified Problem Statement. Existing level of service and security of supply cannot be maintained.

14 Proposed Infrastructure for Site N Watermain Routes Approximately 400m of New 150mm Watermain to Existing Well No. 3 Treatment Facility Power and control systems to be integrated with Well No. 3 Treatment Facility

15 Proposed Infrastructure for Site K Watermain Route Approximately 4,600m of New 150mm Watermain to Existing Well No. 3 Treatment Facility New power and control systems will be independent of Well No. 3 Treatment Facility

20 Preferred Alternative (Preliminary) New Groundwater Production Well (Well #4) at Site N Located approximately 400m north of existing Inglewood Well #3, west of Highway 10 Provides a minimum of 1,295 m 3 /d (900 L/min) of sustainable water supply capacity Groundwater from Well #4 will be pumped directly to the Inglewood Well #3 facility for treatment Modifications to the existing Inglewood Well #3 treatment facility will be required (i.e., additional filter), which may require an increase in the existing building footprint (i.e., addition) within the existing property limits A watermain will be constructed adjacent (parallel) with Highway 10 (Final alignment CVC/MTO to be confirmed during detailed design) Testing indicates that both existing Well #3 and proposed Well #4 can be operated simultaneously
