HomeMy WebLinkAbout2011 - Second Quarter - Richmond Community Water System Quarterly Report for
The Richmond Community Water System
for the period ending June 30, 2011
Waterworks # 260074854
Section 1 - Introduction:
This report is a quarterly summary of 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 Richmond Community 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 Richmond Water 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 Safe Drinking Water Act. Licensing means that an individual
meets the education and experience requirements and has successfully
passed the certification exams.
• Sampling and Analytical Requirements:
The Municipality follows a sampling and analysis schedule required by the
Ont. Regulation 170/03 and 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.
