Rocky Broad at Chimney Rock

Source Information

The Broad Riverkeeper is a program of MountainTrue and a member of the Waterkeeper Alliance. Every week from May to September, Broad Riverkeeper staff, interns, and volunteers monitor water quality at sites across the Broad 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 Broad Riverkeeper Facebook and Instagram pages. MountainTrue utilizes the EPA-approved IDEXX method for collecting and analyzing water samples and, beginning in 2023, compares the results against the EPA's (U.S. Environmental Protection Agency) 2012 Recreational Water Quality Criteria for primary contact of 126 CFU/100 mL. Test results are expressed as Most Probable Number (MPN) of E. coli CFU (colony forming units) per 100 ml. [Please note that prior to 2023, MountainTrue was using 235 CFU/100mL as its threshold value.] A beach is marked Green when single sample results are up to 126 E.coli / 100 ML water. A beach is marked Red when the results are above 126 E.coli / 100 ML water. A gray marking indicates no current data is available. All recreators should be aware that results are preliminary and, while posted as soon as available, represent data that is a day old and should only be used as guidance when assessing exposure risk as bacteria levels can change at any time, especially after heavy rainfall.
