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

Up until the middle of last year, 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.  Virginia no longer has a single sample maximum or any criteria for primary recreational contact in freshwaters.

These are the E. coli concentration results for the water samples that were collected yesterday, Wednesday, June 03, 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.
