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
