TABLE 2SUMMARY OF GROUNDWATER ANALYTICAL RESULTSHYDROGEOLOGICAL ASSESSMENTSTRANGE STREET WATER SUPPLY CLASS EA UPDATENotes:ODWS Technical Support Document for Ontario Drinking Water Standards, Objectives and Guidelines, June 2003, Revised June 2006AODWS Table 1 - Microbiological Standards, Maximum Acceptable ConcentrationBODWS Table 2 - Chemical Standards, Maximum Acceptable ConcentrationCODWS Table 2 - Chemical Standards, Interim Maximum Acceptable ConcentrationDODWS Table 4 - Chemical/Physical Objectives and Guidelines, Aesthetic ObjectivesEODWS Table 4 - Chemical/Physical Objectives and Guidelines, Operational GuidelinesFODWS Table 4 - Medical Officer of Health Reporting Limit6.5 A Concentration exceeds the indicated standard.15.2 Concentration was detected but did not exceed applicable standards.< 0.50 Laboratory estimated quantitation limit exceeded standard.< 0.03 The analyte was not detected above the laboratory estimated quantitation limit.n/v No standard/guideline value.- Parameter not analyzed / not available.c This standard applies to water at the point of consumption. Since lead is a component in some plumbing systems,first flush water may contain higher concentrations of lead than water that has been flushed for five minutes.d Where both nitrate and nitrite are present, the total of the two should not exceed 10 mg/L (as nitrogen).f Refer to ODWS Table 2 for health related standardDFg The aesthetic objective for sodium in drinking water is 200 mg/L. The local Medical Officer of Health should be notified when the sodium concentration exceeds 20 mg/Lso that this information may be communicated to local physicians for their use with patients on sodium restricted diets.h When sulfate levels exceed 500 mg/L, water may have a laxative effect on some people.k Increases in HPC concentration above baseline levels are considered undesirable.The criterion is applicable to total xylenes, and m & p-xylenes and o-xylenes should be summed for comparison.s1V:\01609\active\161110897_strange_st\planning\report\Final Hydrogeo Assessment\tables\tbl 2_GW Results - AB.xlsx161110897Page 1 of 1
