The City of Windsor will open Sandpoint Beach for the first time this year on Friday.
The opening was delayed because of bad weather and high water levels.
Holiday Beach in Amherstburg remains closed because of erosion.
No other beaches are closed this week but the Windsor-Essex County Health Unit said swimming is not recommended at Mettawas Beach in Kingsville because of high levels of E. coli bacteria. Swimmers were also urged to stay out of the water at Mettawas Beach last week.
Warnings are posted when the water samples have E. coli levels that are greater than 200 per 100 millilitres of water and are shut down when the E. coli count is 1,000 per 100 millilitres of water or higher.
Mettawas Beach has an E. coli reading of 228, which is far less than last week's 918.
People can get sick from water with high levels of E. coli. The most common illnesses are stomach and intestinal illnesses such as vomiting and diarrhea, along with lung, eye, ear, nose, or throat infections or skin issues. Swallowing contaminated water is the main way people may get sick.
Health officials have started conducting beach water quality monitoring at all nine public beaches at least once a week. The testing runs from June to September to make sure the E. coli counts in the water are below provincial standards. Beach sampling will take place every Monday and if the beach is closed due to high E. coli levels, it will be resampled on Thursday of the same week. Beach water quality results are released every Wednesday during the summer.
The health unit does not recommend swimming after a heavy rainfall even if the beach is open for swimming.
