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 fishing and boating access point is located in the Wallkill River National Wildlife Refuge, which borders a 10-mile stretch of the Wallkill River along the New York-New Jersey border. Immediately downstream of this point, the Wallkill River enters the Black Dirt agricultural region, where it is artificially straightened and its watershed is drained by manmade channels.
