Straffordville Community Centre/
Bayham Municipal Office
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

Section 2 - Compliance With Provincial Regulations:
The well systems listed above are 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.
Sampling and Analytical Requirements:
Sampling and analysis schedule required by Ontario Regulation 319/08, and the Ontario Drinking Water Standards are fully complied with. More information on sampling and analysis, including
results are available in this report and from the Municipal Wastewater Treatment Plant.
