HomeMy WebLinkAbout2019 - Third Quarter - Bayham Water Distribution System Quarterly Report for The Bayham Water Distribution System for the period ending September 30, 2019 Waterworks # 260004748 Section 1 - Introduction: This report is a summary of the quarterly water quality, published in accordance with Ontario's Drinking Water Protection Regulation. It includes important information regarding the source of water, analytical test results, and how these compare to the standards set by the Province. Section 2 - Compliance With Provincial Regulations: The Municipality of Bayham water system is operated in accordance with provincial regulations. The following is the criteria used: • Use of Accredited Labs: Analytical tests to monitor the water quality are conducted by a laboratory audited by the Canadian Association for Environmental Analytical Laboratories (CAEAL) and accredited by the Standards Council of Canada (SCC). Accreditation ensures that the laboratory has acceptable 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. • Operation by Licensed Operators: The water distribution system is operated and maintained by the Municipalities competent and licensed staff. The mandatory licensing program for operators of drinking water facilities in Ontario is regulated under the Ontario Water Resources Act (OWRA) Regulation 128/04. Licensing means that an individual meets the education and experience requirements and has successfully passed the certification exam. • Sampling and Analytical Requirements: The Municipality follows a sampling and analysis schedule required by the Ontario Regulation 170/03, the Ontario Drinking Water Standards. More information on sampling and analysis, including results are available in this report and from the Municipal Wastewater Treatment Plant. • Adherence to Ministry Guidelines and Procedures: To ensure the protection of the public's health and operational excellence, the Municipality adheres to the guidelines and procedures developed by the Ministry of the Environment and the Ministry of Health.

September 4, 2019 - Water main break along the Port Burwell Secondary before entering the Bayham Water Distribution System resulted in low water pressure and/or no water for the residents in the villages of Vienna and Port Burwell on. A Boil Water Advisory was issue by the Southwestern Public Health — St. Thomas Office on September 4, 2019. The Boil Water Advisory was rescinded on September 9, 2019 after 2 sets of samples came back clear.
