E. coli levels on the Rise

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
