The Haliburton, Kawartha, Pine Ridge District Health Unit monitors recreational water quality at sites in this region. The sampling season starts June 1 and ends August 31. Water at all sites is sampled for E. coli and Total coliform at all sites. 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. 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 is 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. Water samples are collected weekly. Results are posted to Swim Guide as soon as lab results are available. They are also available at https: //www.hkpr.on.ca/2018/06/27/beach-water-testing/ 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.
