Pinery Provincial Park Beach

Information sur la source

Lambton County Community Health Services samples beaches from the end of May to September 1st. Five Lambton beaches (Grand Bend North, Grand Bend South beach, Ipperwash Main Beach, Bright’s Grove Beach including Mike Weir Park, and Canatara Park Beach) have daily water quality results based on a predictive model. Lambton Public Health reviews and validates this predictive model every year. Pinery Provincial Park and C.J. McEwen Beach are sampled on Monday or Tuesday using the persistent beach method (traditional water sampling). When information is updated on Lambton County's website, Swim Drink Fish updates Swim Guide. As of 2018, Ontario beaches are following the Operational Approaches for Recreational Water Guideline, 2018, and the Recreational Water Protocol, 2018, for geometric mean and single-sample maximum parameters. These are now equivalent to those set out in the Guidelines for Canadian Recreational Water Quality – Third Edition, 2012: Geometric mean concentration (minimum of five samples): below 200 E. coli/100 mL, Single-sample maximum concentration: below 400 E. coli/100 mL. (These values replace the previous, more stringent Ontario standard: a geometric mean of less than 100 E. coli/100 mL.) In Swim Guide, a beach is marked Green when the geometric mean of 5 samples collected within a 30-day period is below 200 E. coli / 100 ml of water and the single sample value is below 400 E.coli/100 mL. A beach is marked Red when the geometric mean of 5 samples collected within a 30-day period exceeds 200 E. coli / 100 ml of water and/or exceeds the single sample value of 400 E.coli/100mL. A beach is Grey when reliable or up-to-date information is not available. 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.
