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:

This study site is where the Moordener Kill, which is a medium gradient, warm water stream, with a gravelly substrate, drains its approximately 33 square miles into the Hudson River. The Moordener Kill is an important spawning and nursery area for a variety of coastal migratory fish species. A proposed pipeline route would cross the estuary marsh, a significant feeding area for the protected Atlantic Sturgeon, at the mouth of the Moordener Kill.
