Lambton Public Health is launching its 2026 beach water quality monitoring program on Monday, June 1st, as the summer beach season begins across Lambton County.
Each summer, public health officials test and monitor water at designated beaches to help determine whether it is safe for swimming.
Beach conditions will be shown in two ways. A “posted” warning sign means swimming is not safe due to high bacteria levels that could pose a health risk. A “not posted” caution sign means no issues have been found, but beachgoers are still advised to watch for changes, especially after heavy rain or rough water.
Officials say cloudy water caused by waves or rainfall can sometimes contain higher levels of bacteria.
Lambton Public Health uses a mix of daily predictive monitoring at some beaches and weekly water sampling at others. The program will run until August 28th.
Health officials say the predictive system helps provide faster and more accurate updates about water quality so the public can make safer choices.
Beachgoers can check current conditions by texting “Beach” to 226-909-3003, calling the Beach InfoLine at 519-383-3816 or 1-800-667-1839 ext. 3816, or visiting LambtonPublicHealth.ca.
Daily monitored beaches include Grand Bend North and South, Ipperwash Main Beach, Bright’s Grove (including Mike Weir Park), and Canatara Park. Weekly testing is done at Pinery Provincial Park and Highland Glen Park.
Officials also remind the public that no sampling is done along the St. Clair River, but caution signs are permanently posted at several nearby parks due to the risk of higher bacteria levels after heavy rain.
Lambton Public Health says the program is part of ongoing efforts to track environmental changes and keep residents informed about safe recreation along local beaches.
