No-swim Advisories

Warning Unsafe for Swimming: high levels of bacteria in these waters may pose a risk to your health. Huron County Health Unit sign.

Our beach water quality monitoring program has ended for the 2019 season.

Please visit us again for the 2020 season.

The 2018 Ontario Public Health Standards includes changes for when a no-swim advisory is posted.  A health unit may post a no-swim advisory if the E. coli concentration in the water exceeds the Guidelines for Canadian Recreational Water Quality, 2012.  According to those guidelines, the E. coli concentration for safe swimming at Huron County beaches is:

Geometric mean (geomean) concentration for a minimum of five samples ≤ 200 E. coli colony forming units (CFU) per 100 millilitres (mL)

Health Canada has estimated that 1-2% of swimmers might get a gastrointestinal illness when E. coli levels are ≤ 200 E. coli CFU/100mL.

Based on the number of E. coli colonies in the water, and on an assessment of environmental factors, the health unit may post no-swim advisories at any of the beaches monitored.

None of the beaches monitored are under a no-swim advisory.
