Enterococcus is an EPA-approved fecal contamination indicator.

Samples taken by citizen scientists trained by Riverkeeper, and processed on the Riverkeeper vessel, according to the 2014 Quality Assurance Project Plan.

Rainfall data comes from wunderground.com. Wet weather is a common trigger of fecal contamination.

About this location:

This site is located at The Ashokan Center. An old mill impoundment creates a slow moving area, just downstream of the confluence of the Tongore Creek and the Esopus Creek. There is a beach and a dock. The area is no longer suitable for swimming due to sediment accumulation, but it is used for boat access.
