Two local beaches are closed this week because of high levels of E.coli.
The Windsor Essex County Health Unit's weekly water testing found E.coli counts of 1,000 or higher at Belle River Beach and Colchester Beach.
Swimming is not recommended at Mettawas Beach where E.coli counts are 200 or higher.
All other beaches are safe for swimming.
The health unit tests the water at nine local beaches every Monday. The water at closed beaches is retested before the end of the week.
Results of the water testing can be found here.
