Enterococcus is an EPA-approved fecal contamination indicator.
Samples taken by citizen scientists and processed at laboratories that aren't directly affiliated with Riverkeeper, using methods and study designs that are consistent with Riverkeeper's Hudson River and Citizen Testing programs.
Rainfall data comes from wunderground.com. Wet weather is a common trigger of fecal contamination.
Water Quality scoring is based on the 2012 Recreational Water Quality Criteria from the US Environmental Protection Agency (EPA) for safe swimming. Learn More
