Summer E. coli Testing Program Results for Tuesday, June 19, 2024

As the temperature raises the cool waters of the Shenandoah Rivers maybe calling to you.  The goal of FOSR’s summer E. coli testing program is to provide frequent, real-time accredited E. coli concentration results for river recreation users to make their own informed decision about potential associated health risks when recreating in the areas of the rivers tested.  Below […]

Summer E. coli Testing Program Results for Tuesday, June 11, 2024

Below is the link to the E. coli results for the water samples collected yesterday, 06.11.2024, as part of Friends of the Shenandoah River’s Summer E. coli Testing Program. To confirm the previous 3 consecutive elevated E. coli readings at site FPHCTL, Hawksbill Creek Town of Luray off Virginia Ave., we performed a compliance QC split sample and collected a […]

Friends of the Shenandoah River (FOSR) launched our Summer E. coli Testing Program at public access locations on the Main-stem, South Fork, and North Fork of the Shenandoah River yesterday, Tuesday May 21, 2024. We started this program in 2017 to let you, the river user, make an informed decision as to potential related health risks when engaging […]

Summer E. coli Test Results for Tuesday, August 8, 2023

These are the E. coli results for the water samples that were collected on, Tuesday, August 8, after the rain that came through in some areas on Monday. Two out of 13 of the sites tested exceeded the criteria utilized by FOSR of 235 CFU/100 ml. Prior to October 2019, 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, instantaneous, sample maximum or any criteria for primary recreational contact in freshwaters.

Summer E. coli Test Results for Tuesday, July 26, 2023

These are the E. coli results for the water samples that were collected yesterday, July 26, for FOSR’s Summer E. coli testing program at sites located on the NF, SF, and Main-stem of the Shenandoah River. 1 out of 13 of the sites tested exceeded the criteria utilized by FOSR of 235 CFU/100 ml. Prior to October 2019, 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, instantaneous, sample maximum or any criteria for primary recreational contact in freshwaters.

FOSR’s Summer E. coli Test Results for Tuesday, July 18, 2023

As a benchmark, the FOSR uses the single sample concentration threshold of 235 E. coli colony-forming units per 100 mL of water sample for primary recreational use that was included in the Virginia water-quality standard prior to October 2019.  Meaning that if a single freshwater grab sample had E. coli concentration/levels that exceed 235 CFU per 100mL of water sample then the water was considered unsafe for primary recreational use.  These data represent a snapshot of the water quality on the date, time, and under the conditions that the water sample was collected.

FOSR’s Summer E. coli Test Results for Tuesday, July 11, 2023

These are the E. coli results for the water samples that were collected yesterday, Tuesday, July 11, 2023.  The sites located on the Main-stem, North Fork, and South Fork of the Shenandoah River had relatively low levels of E. coli, while the E. Coli levels in Manassas Run however remain elevated.
