Test Results for July 17, 2024

As the summer of 2025 comes to a close, Friends of the Shenandoah River (FOSR) has completed its final E. coli monitoring event for the season. Of the 14 sites tested on Thursday, September 18,

Unfortunately, no, the E. coli level measured in the Shenandoah River at Lockes Landing public boat landing (site FC05) in Clarke County, VA was 248.1 MPN (most probable number) of colony-forming units per 100 mL

Great news heading into the holiday weekend, with no rain in the forecast, we’re hopeful that E. coli levels will stay consistent with yesterday’s results at the river sites we tested, which were all below

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 of water sample. As in

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

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 the Luray-Hawksbill Greenway Pocket Park.

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! From fishing and kayaking to

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 of 365.4 CFU/100mL exceeded the

Folks, the E. coli levels measured for the water samples collected and tested yesterday, July 16, may no longer represent current water quality.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 water quality results reflect E.

There was a noticeable decrease in the E. coli levels at all of the sites monitored yesterday, Wednesday July 09, compared to a week ago. However, the E. coli level at three of the sites

All four sites tested on the Shenandoah River Main-stem, along with three sites on the South Fork and three on the North Fork, had elevated E. coli levels exceeding the EPA’s recommended “do not exceed”

The water levels at all the sites we tested have decreased since last week, additionally, at many of the sites the water was less turbid/muddy, improving the water’s clarity. In the midst of this recent

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
