Key Information

The concentration of Enterocci bacteria in beach water samples is measured in cfu/100ml (colony forming units per 100 milliliters). Beach closures are based on exceedances of more than 60 cfu/100 ml in saltwater and in freshwater.

Collection Period

Sample data is available from 2000 to present.
