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.

What do the Numbers Mean?
