E. coli levels on the Rise

E. coli levels crept up at all of the sites that we collected water samples from yesterday.  At three of the sites, the E. coli levels exceeded the previous Virginia water-quality standard threshold of 235 E. coli colony-forming units per 100 mL of water sample for primary recreational use.

FW36 – Manassas Run upstream of the confluence with main-stem Shenandoah River, just upstream of the public boat landing, 272.2 MPN of E. coli colony-forming units per 100 mL

FW35 –Main-stem Shenandoah River at Morgan’s Ford low H2O bridge public boat landing below the confluence with Manassas Run, 275.5 MPN E. coli colony-forming units per 100 mL

FSMB – North Fork of the Shenandoah River at Meems Bottom, 435.2 MPN E. coli colony-forming units per 100 mL

The thing that was most noticeable yesterday when we were out collecting the water samples at the various sites was the low water levels for this time of year.

Previously in Virginia, if a single freshwater grab sample contained E. coli bacteria levels that exceeded 235 CFUs then the water would have been considered unsafe for primary recreational contact. Under the current Virginia Code, effective as of October 2019, for both the State Water Control Board and VA Dept. of Health, there is no longer any agency responsible to inform the public of potential exposure to elevated E. coli levels in the freshwater streams and rivers in Virginia!

The Friends of the Shenandoah River have been providing this accredited E. coli data to you so that you can make an informed decision of the potential related health risks before engaging in primary recreational use activities in the river.

Welcoming Summer 2021: FOSR’s 1st Summer E. coli Results

The thunderstorms that passed through Wednesday afternoon made for a beautiful day on Thursday to be out collecting the water samples for FOSR’s first 2021 Summer Quantitative E. coli Test Results at public recreational use sites on the Main Stem, South Fork, and North Fork of the Shenandoah River and the Opequon Creek.

Unfortunately, at this time, we are not able to include all of the sites that we monitored as in previous summers due to the lack of funding necessary to provide this vital resource to you.  If you wish to support FOSR’s Summer E. coli testing program, please donate via PayPal http://fosr.org/join-us/join/

Only with your support

This past year has seen a monumental increase in the use of public natural areas. The community has come to rely on the weekly E. coli concentration results updates from FOSR’s annual summer E. coli testing program at public access and recreational sites on the Shenandoah River. The goal of this program is to provide frequent, real-time accredited E. coli concentration results for river recreation users to make an informed decision about potential associated health risks when recreating in the areas of the river tested. The weekly quantitative E. coli concentration results are available to the public on both the FOSR website and Facebook page. The public’s interest in this program has been overwhelmingly positive. As a reminder of potential health risks when recreating in high flow, muddy, and/or turbid waters, the FOSR coined the slogan, “When it’s Brown, Turn Around”. Many times, when out collecting the water samples, FOSR staff is greeted with river goers calling out, “When it’s Brown, Turn Around”

FOSR’s 2020 Summer E. coli Results through 09.24.2020

Sorry about not posting the E. coli results for the water samples that were collected last week on Thursday, September 17,  in a timely manner.   We had technology difficulty which required the purchase of a new computer.  This pdf file contains the E. coli concentration results for the water samples collected on Thursday, September 17, and yesterday, Thursday, September 24.  Contact recreational use of the river is quieting down as the water temperatures are dropping and the sunsets are earlier.

“IF IT’S BROWN TURN AROUND”.

Depending on where you were in the Shenandoah River watershed yesterday, Thursday, September 10, 2020, the E. coli levels varied greatly.  The two pictures below illustrate the contrasting differences in    E. coli concentrations at different sites.

Previously in Virginia, if a single freshwater grab sample contained E. coli bacteria levels that exceeded 235 CFUs then the water would have been considered unsafe for primary recreational contact. Under the current Virginia Code for both the State Water Control Board and VA Dept. of Health, there is no longer any agency responsible to inform the public of potential exposure to elevated E. coli levels in the freshwater streams and rivers in Virginia!  These are the E. coli results for the water samples collected yesterday, Wednesday, September 02, 2020.

“IF IT’S BROWN TURN AROUND”.

Yesterday, Wednesday, September 02, 2020, the South Fork of the Shenandoah River was transporting silt, sediment, debris, garbage, logs, and high levels of bacteria.  After the North Fork and South Fork combined making the Main-stem of the Shenandoah River, the lower bacteria levels and less turbid waters in the North Fork helped to dilute the bacteria levels coming from the South Fork.

FOSR’s 2020 Summer E. coli Results through 08.25.2020

Measurable rain events have been occurring in the southern region of the Shenandoah River watershed, which includes the North River, South River, and Middle River that are the headwaters of the South Fork of the Shenandoah River.  One of the effects of these storms has been elevated E. coli levels in the South Fork and Main-stem of the Shenandoah.

These are the E. coli results for the water samples that were collected yesterday, Tuesday, August 25, 2020.

When its brown, turn around!

The effect of the rains from the southern region of the watershed is traveling downstream.  Yesterday, the South Fork and Main-stem of the Shenandoah River was still running high and muddy/discolored.  The      E. coli levels at all five of the sites tested on the South Fork and the five sites tested on the Main-stem, including Manassas Run, exceeded the previous instantaneous Virginia water quality standard threshold of 235 E. Coli CFUs per 100ml of sample for primary recreational contact.

These are the E. coli results for the water samples that were collected yesterday, Wednesday, August 12, 2020.

FOSR 2020 Summer Quantitative E. coli Concentration Results through 08.12.2020

At the following sites the E. Coli level exceeded the previous instantaneous Virginia water quality standard threshold of 235 E. Coli CFUs per 100ml of sample for primary recreational contact:

  • FW36, Manassas Run upstream of the confluence with the Shenandoah River at Morgan Ford low water bridge in Warren County 1119.9 MPN E. coli CFU per 100mL/sample

 

The effect of the heavy rains that occurred in Augusta and Rockingham counties last week can still be seen in the South Fork in Luray and Warren Counties and the Main-stem of the Shenandoah River in Clarke County and beyond.
