HomeMy WebLinkAbout2020 - First Quarter - Richmond Community Water SystemQuarterly Report for
The Richmond Community Water System
for the period ending March 31, 2020
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.

Section 5 - Discussion of Analytical Results:
It was found through thorough sampling that there was no microbiological exceedences for this quarter. Low level treated chlorine residuals and high level treated turbidity results
as noted above are as a result of equipment calibrations, which do not represent non-compliance.

Section 7 - Definitions and Abbreviations:
MAC - Maximum Acceptable Concentration.
IMAC - Interim Maximum Acceptable Concentration.
Coliform Bacteria - A group of commonly occurring rod shaped bacteria. Their presence in a water sample is indicative of inadequate filtration and/or disinfection.
Fecal Coliform Bacteria - Refers to a subgroup of coliform bacteria present in the digestive system of warm blooded animals and humans.
Heterotrophic Plate Count (HPC) - A method of measuring bacterial content in water samples. Also known as Standard Plate Count.
Organic Parameter - A group of chemical compounds containing carbon.
Inorganic Parameter - A group of chemical compounds not containing carbon.
Raw Water - Surface or ground water available as a source of drinking water that has not received any treatment.
