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.

What do the Numbers Mean?

About this location:

This location is in the mouth of the Roe Jan, where there is tidal influence. Directly upstream from here, the Roe Jan flows through a riparian zone of uninterrupted forest for about two miles, until the next sampling site at the Sportsman's Club. These samples are collected by Roe Jan watershed residents and processed by the Bard Water Lab. Site photo credit: Kaare Christian.
