E. coli levels crept up at all of the sites that we collected water samples from yesterday. At three of the sites, the E. coli levels exceeded the previous Virginia water-quality standard threshold of 235 E. coli colony-forming units per 100 mL of water sample for primary recreational use.
FW36 – Manassas Run upstream of the confluence with main-stem Shenandoah River, just upstream of the public boat landing, 272.2 MPN of E. coli colony-forming units per 100 mL
FW35 –Main-stem Shenandoah River at Morgan’s Ford low H2O bridge public boat landing below the confluence with Manassas Run, 275.5 MPN E. coli colony-forming units per 100 mL
FSMB – North Fork of the Shenandoah River at Meems Bottom, 435.2 MPN E. coli colony-forming units per 100 mL
