HYDROGEOLOGICAL ASSESSMENTSTRANGE STREET WATER SUPPLY CLASS EA UPDATEREGIONAL MUNICIPALITY OF WATERLOOMethodology for Test WellMarch 19, 2012Water level data collected during the performance testing are presented on hydrographs foreach monitored location in Figures 8 and 9.3.9 GROUNDWATER SAMPLING AND TESTINGGroundwater from K-SS-TW1-11 was sampled on March 9, 2011 at the end of welldevelopment (~8 hours), on June 13, 2011, 1.5 hours after the commencement of theperformance testing, and on June 14, 2011 at the end of the performance testing. All sampleswere analyzed for general chemistry, DOC, nutrients, metals, and inorganic parameters. Thesample collected on June 14, 2011 was also analysed for volatile organic compounds (VOCs),and microbiology parameters. None of the raw water samples were filtered and thereforeresults represent total concentrations.The samples were collected from the discharge hose and placed directly into appropriatelaboratory supplied sample containers. Samples were placed in coolers with ice and deliveredto Maxxam Analytics Inc. (Maxxam) under chain-of-custody documentation. The analyticalresults are summarized in Table 2 and compared to the ODWS. Appendix J contains a copy ofthe Laboratory Certificates of Analysis and chain-of-custody forms.hls v:\01609\active\161110897_strange_st\planning\report\final hydrogeo assessment\final\fnl_rpt_120319.docx 3.5
