FOSR’s 2020 Summer E. coli Results through 06.10.2020

FOSR’s Summer E. coli Testing Project at public access and recreational use areas on the Main Stem, North Fork, and South Fork of the Shenandoah River and Opequon Creek

In cooperation with the Warren County Board of Supervisors, additional sites are being added on Manassas Run to assist in isolating areas contributing to the elevated E. coli levels the FOSR has documented in the watershed.

These are the E. coli concentration results for the water samples that were collected yesterday, Wednesday, June 10, 2020.  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.

For years Virginia’s water quality standard for freshwater beach advisories or closures was a single sample maximum of 235 E.coli CFU/100 ml of sample.  As of last year, Virginia no longer has a single sample maximum or any criteria for primary recreational contact in freshwaters. Under the recently approved Virginia Code for both the State Water Control Board and VA Dept. of Health, there is no longer any Virginia State agency responsible to inform the public of potential exposure to elevated E. coli levels in freshwater streams and rivers in Virginia.
