Lambton Public Health has launched its 2025 beach water monitoring program. Beaches across Lambton County will be tested regularly to help ensure they are safe for swimming throughout the summer.
Health officials will use two methods to monitor water quality, predictive models and lab-tested water samples. Beaches will be marked with signs to show their safety level. If a beach is marked “Posted,” it means the water has high levels of bacteria and is unsafe for swimming. A “Not Posted” sign means the water is currently safe, but swimmers should still use caution, especially after heavy rain or if the water appears cloudy.
Five popular beaches will be monitored daily using predictive models: Grand Bend North, Grand Bend South, Ipperwash Main Beach, Bright’s Grove (including Mike Weir Park), and Canatara Park. Pinery Provincial Park and Highland Glen Park will have their water sampled weekly and tested in a lab.
Beach monitoring will continue until Friday, August 29th. People can check beach safety reports in three easy ways: text the word “Beach” to 226-909-3003, call the Beach InfoLine at 519-383-3816 (or toll-free at 1-800-667-1839 ext. 3816), or visit LambtonPublicHealth.ca.
While the St. Clair River beaches won’t be tested, permanent signs at Branton Cundick Park, Brander Park, and Seager Park warn swimmers to be careful after heavy rain due to the risk of high bacteria levels.
