MONITORING FREQUENCY

Illinois Beach State Park South is sampled from May 23rd to August 31st

SOURCE INFORMATION

Lake County Health Department monitors the majority of beaches 4 days per week from Memorial Day to Labour Day. When sample results are reported on the County's website, Lake Ontario Waterkeeper updates Swim Guide.

Recreational public beaches in Illinois are tested at least once every week, typically from May to September. In popular beach areas such as Chicago, beaches are tested five times per week or even daily. Illinois beaches are posted when a single sample exceeds 235 E. coli / 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.
