HYDROGEOLOGICAL ASSESSMENTSTRANGE STREET WATER SUPPLY CLASS EA UPDATEREGIONAL MUNICIPALITY OF WATERLOOBackground ReviewMarch 19, 2012• Aquifer Shutdown Test (Terraqua, 1995);• Kitchener Westside Pumping Test (Stantec, 2000);• K19 Aquifer Test (Stantec, 2005);• K11A Aquifer Test (Burnside, 2007);• Mapping of Shallow and Deep Potentiometric Surfaces (AquaResource, 2009); and• Tier 3 Water Budget and Water Quality Risk Assessment (Stantec, 2009).Groundwater flow within the Strange Street Well Field follows the general regional trendsdescribed above, with the predominant flow direction within Aquifer 1 being from west to east.Groundwater flow under pumping and non-pumping conditions was recently investigated and asummary of all previous reports can be found within the Tier 3 Water Budget and Water QualityRisk Assessment Report (Stantec, 2009).The recharge source area for the Strange Street Well Field was evaluated in Terraqua (1995).Terraqua (1995) concluded that the water captured by the well field is recharged locally.2.4 WELL FIELD DESCRIPTIONThe Strange Street Well Field is located within the northwest portion of the City of Kitchener andis generally spread out over an area of approximately 1.0 km 2 . The well field is divided into twogeneral areas. Production Wells K11A, K13, K18 and K19 are located in the western portion ofthe well field, in the vicinity of the Westmount Golf & Country Club (Figure 1). With theexception of the golf course, which is zoned as open space, land use in this area ispredominantly residential. Production Well K10A is located approximately 1 kilometer (km) tothe east on Gage Avenue within an area that is zoned as industrial/mixed use with residentialintermixed (Figure 1).The first wells for the Strange Street Well Field were constructed around 1910 and a pumpingstation was constructed in 1923. By the time the pumping station was constructed, there wereat least (9) wells installed to depths ranging from 14 m to 91 m below ground surface (BGS).The water supply for the Strange Street Well Field is currently obtained from Production WellsK10A, K11A, K13, K18 and K19. Production Wells K10, K11, K12, K14, K14A, K15, K16 andK17, which have been used historically for water supply purposes, have either been abandonedor replaced due to poor water quality or a decline in well yield. A detailed history of the StrangeStreet Well Field was documented in Stantec (2000). The following provides a brief summary ofthe status of the currently active production wells:• Production Well K10 was constructed following a test drilling program in 1935, and wasabandoned as a water supply source following the construction of Production Well K10A in1982. Production Well K10A is currently used as a water supply source;hls v:\01609\active\161110897_strange_st\planning\report\final hydrogeo assessment\final\fnl_rpt_120319.docx 2.7
