Two of the ten beaches in Windsor-Essex have warnings posted this week.
The Windsor-Essex County Health Unit says Mettawas Beach in Kingsville and Sandpoint Beach in Windsor are unsafe for swimming because high levels of bacteria in the water may pose a health risk.
Mettawas Beach has been under a warning all summer, while Sandpoint Beach has been under a warning for the last three weeks.
Water sampling is done each Monday throughout the summer.
