Half Moon Bay – Weekly Water Sample Results
EPA assess short-term water quality by comparing results against a dry weather enterococci trigger (>200 org/100mL). Prior to the 2018-19 summer, a trigger of >400 org/100 mL was used. Twice daily forecasts predict likelihood of stormwater pollution during and after rain that may cause high enterococci levels.
