Amherstburg Water Treatment Plant Quarterly Report Operated by the Ontario Clean Water Agency (OCWA) under contract to the Town of Amherstburg For the period ending: December 31, 2002 <br />Introduction This report is a summary of the last quarter's water quality, published in accordance with Ontario’s Drinking Water Protection Regulation. It includes important information <br />regarding the source of your water, analytical test results, and how it compares to standards set by the Province. If you have any questions regarding this report, please contact our <br />Client Services Representative listed in section 3 below. During this quarter, the Ontario Clean Water Agency (OCWA) conducted more than 96 bacteriological tests for water quality parameters. <br />Of those tests, 1 sample was found to exceed the Ontario Drinking Water Standards as set out in Ontario Regulation 459/00 for Background Coliform. As a result, we actively undertook <br />the following remedial actions of re-sampling flushing and an increase in distribution chlorine ?chlorine residual. Compliance With Provincial Regulations OCWA operates your water facility <br />in accordance with provincial regulations. Here is how we do it: ?? Use of Accredited Labs: Analytical tests to monitor your water quality are conducted by a laboratory audited by the <br />Canadian Association for Environmental Analytical Laboratories (CAEAL) and accredited by the Standards Council of Canada (SCC). Accreditation ensures that the laboratory has acceptable <br />laboratory protocols and test methods in place. It also requires the laboratory to provide evidence and assurances of the proficiency of the analysts performing the test methods. <br /> <br />Quarterly Report Page 2 ?? Operation by Licensed Operators: Your water treatment plant is operated and maintained by the OCWA’s competent and licensed staff. The mandatory licensing <br />program for operators of drinking water facilities in Ontario is regulated under the Ontario Water Resources Act (OWRA) Regulation 435/93. Licensing means that an individual meets the <br />education and experience requirements and has successfully passed the certificate exam. ?? Sampling and Analytical Requirements: OCWA follows a sampling and analysis schedule required <br />by OWRA Regulation 459/00, the Ontario drinking Water Standards. More information on sampling and analysis including results are available in this report and from your municipal office. <br />?? Adherence to Ministry Guidelines and Procedures: To ensure the protection of the public health and operational excellence, the OCWA adheres to the guidelines and procedures developed <br />by the Ministry of Environment and the Ministry of Health.

On October 24th. we received a sample with a high background count of >2500. That was followed up with 3 special samples collected upstream down <br />stream and at the original sample location for consecutive three days. All special sample results were negative. No follow-up action was determined necessary. <br /> <br />Quarterly Report Page 4 Availability of Analytical Test Results The certificate of approval from the Ministry of the Environment, and Regulation 459/00 set out monitoring requirements <br />for your water. The tables above summarize all the results required for inclusion in quarterly reports. Your water is extensively tested for the presence of dozens of compounds. Some <br />compounds, not listed above, may be present in low concentrations and their presence does not necessarily mean that the water poses a health risk. Results of all analytical tests are <br />available through your municipal office. A requirement of the facility Certificate of Approval (Cof A) is a Compliance Report which must be completed and made available not later than <br />March 31. Upon completion, this report will be located at the Municipal Office were it can be inspected. Definitions and Abbreviations ?? MAC -Maximum Acceptable Concentration. ??
