This week we collected the  water samples from the sites located in Clarke County on the Main-stem of the Shenandoah River and the one water sample from Opequon Creek on Monday, September 16 for the E. coli testing program.  We then collected the rest of the water samples on Tuesday, September 17.   Below are the E. coli concentration results for the water samples that were collected on both September 16 and 17.  In a freshwater system, these data represent a snapshot of the water quality on the date, time, and under the conditions that the water sample was collected.

FOSR 2019 Summer Quantitative E. coli Concentration Results through 09.17.2019

At 1 of the 15 sites tested on September 16 and 17, 2019 the E. coli levels exceeded the Virginia Water Quality Standard threshold level of 235 colony forming units of E. coli per 100 ml of sample for freshwater beaches.  This site was:

• FW36, Manassas Run, a tributary the feeds into the Main-stem Shenandoah River just upstream of the public boat landing at Morgan’s Ford Bridge on Morgans Ford Road, Warren County
