Water Quality Test Results

Starting in 2018, reported units of measure have been updated to match the units of measure included within Ontario Regulation 169/03 - Ontario Drinking Water Quality Standards.

Reported results that are shown with a less than symbol (<) before the value indicates that the sample result is below the lowest possible detection limit for the parameter.

Microbiological

Total Coliform and E.coli bacteria tests are performed on raw, treated and distributed drinking water.

Microbiological testing done under the Schedule 10, 11 or 12 of Regulation 170/03, during this reporting period.

Test Number of Samples Range of E.Coli or Fecal Results (minimum number)-(maximum number) Range of Total Coliform Results (minimum number)-(maximum number) Number of HPC* Samples Range of HPC Results (minimum number)-(maximum number)
Raw 52 0-260 0-690 Not applicable Not applicable
Treated 104 0 0 104 0-8
Distribution 106 0 0-1 106 0-6

*HPC (heterotrophic plate count) bacteria indicate biological growth. They are not harmful to humans and do not represent poor drinking water quality.

Operational

Operational testing done under Schedule 7, 8 or 9 of Regulation 170/03 during the period covered by this Annual Report.

Test Number of Samples Range of Results (minimum number)-(maximum number)
Turbidity 8760 0.07-0.023 NTU*
Chlorine 8760 0.44-1.91 mg/L
Fluoride Not applicable  

*NTU (nephelometric turbidity units) is a unit that measures the lack of water clarity.

An analyzer continuously monitors the water treatment process and records results on a predetermined frequency. Continuous monitors use 8760 as the number of samples.

Summary of additional testing and sampling carried out in accordance with the requirement of an approval, order or other legal instrument.
