The Green Riverkeeper is a program of MountainTrue and a member of the Waterkeeper Alliance. Every week from May to September, Green Riverkeeper staff, interns, and volunteers monitor water quality at sites across the Green River Watershed. Weekly results are posted on Fridays so you know where it's safe to swim, fish, and paddle on your weekend adventures. Results will be communicated through the Swim Guide mobile app and website, as well as the Green Riverkeeper Facebook and Instagram pages.
The Green Riverkeeper utilizes the EPA-approved IDEXX method for collecting and analyzing water samples and compares the results against the EPA standard for health of 235 E.coli cfu/100 ml. Test results are expressed as Most Probable Number (MPN) of E. coli cfu (colony forming units) per 100 ml.
A beach is marked Green when single sample results are under 235 E.coli / 100 ML water.
A beach is marked Red when the results are equal to or above 235 E.coli / 100 ML water.
A beach is marked Grey when there are no current results or there is no available
information.
