The E. coli levels at all the River sites and Manassas Run (FW36, Warren County VA) tested were below the EPA’s recommended “do not exceed” threshold of 235 CFU of E. coli bacteria per 100mL of water sample.
However, Hawksbill Creek showed a significant increase, with a measurement of 1119.9 MPN E. coli CFU/100mL. This is approximately five times higher than both last week’s result and the EPA’s threshold for issuing early alerts to freshwater recreators.
These results provide a snapshot of the E. coli bacteria concentrations at the designated sites on the date, time, and under the conditions that the water samples were collected.
Heads up, folks! The water sample results from yesterday’s testing are in — and it’s not good news Due to high levels of bacterial contamination from fecal matter at the majority of the sites tested
On June 11, 2025, while collecting water samples for Friends of the Shenandoah River’s summer E. coli testing program, we observed that the North Fork appeared significantly more turbid and had higher E. coli levels
Did you know your donation of any amount will help continue this testing program? https://fosr.org/donate/ Good news for the Shenandoah River sites we tested on June 4! All 13 public access sites showed E. coli
The results of the water samples collected yesterday, Thursday, May 29, show that 11 out of 14 testing sites along the Shenandoah River at public access sites had E. coli levels above the U.S. Environmental
We have officially launched our 2025 Summer E. coli Testing Program! Last week’s measurable rainfall appears to have helped flush out contaminants that accumulated during the drought. As a result, E. coli levels were low
With community interest and support we were able to collect a water sample at site FPHCTL on Hawksbill Creek yesterday, Thursday October 3, catching the tail end of the flooding caused by rains from the

The two sites that have routinely exceeded freshwater Beach Action Value (BAV) of 235 CFU of E. coli bacteria per 100 mL of water sample are tributaries. Site FPHCTL located on the Hawksbill Creek of
Friends: This week’s testing results show the E. coli levels at all monitored sites, except one, were below the EPA’s recommended “do not exceed” threshold of 235 CFU per 100mL
The E. coli levels at all the River sites and Manassas Run (FW36, Warren County VA) tested were below the EPA’s recommended “do not exceed” threshold of 235 CFU of
In addition to lower water levels, mostly clearer conditions, and cooler temperatures this week, we observed a significant change in the E. coli level at our Hawksbill Creek site near
While collecting water samples yesterday along the North Fork, South Fork, and Main-stem of the Shenandoah River, we couldn’t help but notice how many people were out enjoying the River!
At only one River site this week, the northernmost testing site on the Main-stem Shenandoah River, FC08 Castleman’s Ferry public boat launch in Clarke County VA, the E. coli level
Folks, the E. coli levels measured for the water samples collected and tested yesterday, July 16, may no longer represent current water quality. It is important to remember that the
