Beach Water Testing

Beach Water Testing:

To assess and assure water quality of swimming beaches owned and operated by Fond du Lac County, Wolf Lake Beach is tested regularly for high E.coli levels during the swimming season. 

Beach Advisory:

A beach advisory sign is posted whenever the level of E.coli exceeds 235 CFU/100 mL. The beach advisory sign is removed when the levels of E. coli are below 235 CFU/100mL in two samples, each collected on separate days.

Beach Closure:

A beach closure sign is posted whenever the amount of E. coli exceeds 1000 CFU/100mL. The beach will be reopened when the levels of E.coli are below 1000 CFU/100mL in two samples, each collected on separate days.

 

What is E. coli?

E. coli is a type of bacteria that lives in your digestive system, that normally doesn’t cause any illness. But, when E. coli is present in high levels or when different kinds of the bacteria are present, people can get very sick. Symptoms of an E. coli infection are diarrhea, stomach cramps and pain, and nausea or vomiting

Elevated E. coli readings increase swimmers risk of developing an E. coli infection, leading to diarrhea, stomach cramps and pain, and nausea or vomiting.
