How is the classification made?
A point is considered suitable when in 4 of the last 5 samples the E. coli concentration result is less than 800 MPN/100mL, provided that the most recent result is also less than 2,000 MPN/100mL.
Heavy rainfall can affect bathing water quality due to street washing, sewage pump station overflows, saturated contaminated soils, illegal connections to storm drains, among others.
