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.

About this location:

The greatest decline in water quality in the Wynants Kill occurred in the reach where the creek enters the city of Troy. Previous water quality assessments at this site have ranged from slightly impacted to moderately impacted. No specific sources are known that may contribute these contaminants, and the problems are thought to result from historical contamination and urban runoff.
