Good Steward's staff and volunteers monitor 8 sites bi-weekly from Memorial Day to Labor Day, switching to monthly after the swim season. Please see threshold explanation below or feel free to contact us! (336) 613-6109 or Steven@DanRiverkeeper.org
Sites are tested for E. Coli and follow the EPA standard of 235 colonies per 100 ml, expressed as most probably number (MPN), as measured by the IDEXX Quanti-Tray system.
A site is marked Green when results are equal or below 235 colonies/ 100 ML of water.
A site is marked Red when results are above 235 colonies/ 100 ML of water.
A site is marked Grey when there are no current results or there is no available information
