Section 1 - Introduction:
This report is a summary of the first quarter's 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 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 the OWRA Regulation 170/03,
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.
• 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.

Typical Source of Microbial contaminants, such as viruses and bacteria, may come from
Contamination septic systems, agricultural livestock operations, wildlife, and wastewater
treatment plants.
Section 4 - Discussion of Analytical Results:
It was found through thorough sampling that there were two microbiological
adverse result during this time period, resampling however brought the sites into
compliance.
Section 5 - List of all Compounds Detected in Analysis of Water Samples:
As water travels over the surface of the land or through the ground it dissolves
naturally occurring minerals and, in some cases may pick up substances
resulting from the presence of animal or human activity.
The well water is extensively tested for the presence of dozens of compounds.
The results of all analytical tests are available at the municipal wastewater
treatment plant. The following table lists all compounds detected during these
tests.
Parameter Compound MAC or IMAC
19.5 mg/L at office, 19.1
Nitrates mg/L at the library and 10 mg/L MAC
11.9mg/L at the firehall
Sodium All sites exceed, values 20 mg/L MAC
range from 97-138 mg/L
• All facilities are posted non-potable and bottled water is provided.
Section 6 - 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.
