Enterococci are enumerated using EPA Method 1600. The EPA has determined that this group of bacteria is the best indicator of recent fecal contamination of recreational water. Water with enterococci counts (CFU) up to 104/100ml is considered safe for swimming or boating. Counts highlighted in red exceed that limit. A clickable Google map of these sites is posted - see the map link next to this link. Questions? Please contact Sally Hornor at sghornor@aacc.edu or 410 777 2842.
