Beach Water Testing 2018


Water quality samples are taken Monday mornings for every location; weekend and rainfall sampling are suspended for the remainder of the 2018 swim season.

Beaches are closed and signage will be posted when a sample has an E. coli count greater than 1000. An additional sample will be taken immediately and the beach will reopen only when a count is below 1000.

Beaches are under "Advisory" if a sample has an E. coli count over 235, "Advisory" signage will be posted. An additional sample will be taken immediately and the beach advisory will remain in place until the E. coli level is reported to be less than 235 cfu/100mL. "Advisory" is in effect when counts exceed the EPA’s good water quality guidelines, but does not warrant closing the beach at that time.

Testing is based on E. coli colonies per 100ml
