About This Data
E. coli data is sourced from the EPA/USGS Water Quality Portal (waterqualitydata.us) for Ohio and New York beaches. Beach monitoring is seasonal (typically May through September). Outside that period, the most recent available sample is shown. Pennsylvania (Erie County) does not publish to the federal system. Visit eriecountypa.gov for Presque Isle beach results. The EPA advisory threshold is 235 CFU/100mL for a single sample.
