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 exploratory sampling site provides an upstream background for comparing with the Old Stone Bridge site. As of 2014, samples are collected here only when the outfall is flowing. The site name comes from the gently sloping, bedrock bank at this site. This part of the creek is used for fishing.
