SOURCE INFORMATION

Recreational public beaches in Wisconsin are tested May through September. High priority beaches are sampled at least five times per week. They are posted when a single sample exceeds 235 E. coli / 100 ml or when the geometric mean of samples collected over a 30-day period exceeds 126 E. coli / 100 ml. Medium priority beaches are sampled at least twice per week. Low priority beaches are sampled at least once per week. They are posted when a single sample exceeds 235 E. coli / 100 ml. All beaches will be closed if E. coli in a single sample exceeds 1,000 / 100 ml.

In the USA, the Environmental Protection Agency has two sets of recommendations for freshwater and marine beaches. A single sample at a freshwater beach should not exceed 235 E. coli / 100 ml of water. A single sample at a marine beach should not exceed 104 Enterococci / 100 ml of water. The geometric mean of 5 samples from a freshwater beach should not exceed 126 E. coli / 100 ml of water. The geometric mean of 5 samples from a marine beach should not exceed 35 Enterococci / 100 ml of water. States may choose to use this standard or they may substitute a standard that is "as protective as" the EPA's recommendation. The Beach Act is the nation's primary beach protection law.
