Source Information

The Haliburton, Kawartha, Pine Ridge District Health Unit monitors recreational water quality at sites in this region. The sampling season starts June 15 and ends August 31. Samples are collected weekly and tested for E. coli and Total coliform at all sites. Samples are typically taken on Monday of Tuesday and results are posted within 48 hours. The Haliburton, Kawartha, Pine Ridge District Health Unit issues beach advisories when the geometric mean concentration of at least five samples is above 200 E. coli / 100 mL of water or when a single sample is above 400 E. coli / 100 mL of water. This guideline comes from Canada’s Guidelines for Canadian Recreational Water Quality (2012). It is applied to beaches in Ontario in accordance with Ontario’s Recreational Water Protocol, 2018. Results are posted to Swim Guide as soon as they become available. Results are also available at https://www.hkpr.on.ca/2018/06/27/beach-water-testing/. Prior to 2018 beaches in Ontario were posted when the geometric mean of 5 samples collected within a 30-day period exceeded 100 E. coli / 100 mL of water. In Swim Guide, a beach is marked Green when the geometric mean of at least 5 samples is below 200 E.coli / 100 mL water and each individual sample concentration are below 400 E.coli / 100 mL. A beach is marked Red when the results are equal to or above a geometric mean of 200 E.coli / 100 mL water and/or 400 E.coli / 100 mL. A beach is marked Grey when there are no current results or there is no available information. A Ministry of the Environment Procedure (F-5-5) says that a clean beach is open at least 95% of the swimming season, even if it is near a sewage pipe or combined sewer outfall. This rule applies to every place that is public, accessible, and feels like a good place to swim. When all else fails, the Ontario Environmental Protection Act strongly states that no one can interfere with the use that you can make of a public waterway - like swimming! DISCLAIMER: Historical data from 2017 and prior reflect the previous Ontario standard of a geometric mean of 100 E. coli /100 mL. Historical data from 2018 onward reflect the new Ontario Operational Approaches for Recreational Water Guideline, 2018: Geometric mean concentration 200 E. coli/ 100 mL and single-sample maximum concentration of 400 E. coli /100 mL.
