FOSR’s Summer E. coli Testing Project, Providing frequent, accredited E. coli concentration results for river recreation users

The goal of FOSR’s summer E. coli testing project 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 river tested.

If fecal coliform is detected in the water, it indicates that there was recent fecal contamination in the water systems.  Detection of E. coli bacteria in the water indicates recent fecal contamination as well as a possible presence of other disease-causing microorganisms or pathogens.  As the level of E. coli bacterium increases the potential health risk from exposure to pathogenic organisms also increases.

Signs and symptoms of exposure to waterborne diseases may include;

  • Gastrointestinal illnesses such as
    • gas
    • abdominal cramping
    • diarrhea
    • nausea, which may result in vomiting
    • loss of appetite
  • Urinary tract infections
  • Respiratory infections
  • Conjunctivitis (pink eye)
  • Exposure to open wounds by the waterborne pathogens can cause infections of the wound that may result in extended, and sometimes painful, healing time.
  • In rare causes developing a life-threatening form of kidney failure called hemolytic uremic syndrome

In mild to moderate cases, one may not associate their symptoms with recent water related recreational activities especially if the symptoms do not manifest until three or four days later.  Also, not all people will be affected to the same degree; young children, the elderly, and those with weakened immune systems are at a higher risk of experiencing illness and more serious complications caused by harmful E. coli bacteria and associated pathogens.

FOSR 2019 Summer E. coli Results through 07.02.2019

Here are this week’s quantitative E. coli concentration results from the 15 public access and recreational use sites located on the Main-stem, North Fork and South Fork of the Shenandoah River, and the Opequon Creek being tested by the Friends of the Shenandoah River.  The water samples were collected on Tuesday, July 02.

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.

The E. coli concentration results for the water samples collected on July 02, 2019 indicated that the following sites surpassed the Virginia Water Quality Standard threshold level of 235 colony forming units of E. coli per 100 ml of sample for freshwater beaches:

Manassas Run, FW-36, above the confluence with the Shenandoah River at Morgan’s Ford low water bridge in Warren county

Opequon Creek, FCOC, off Neill Road at ford in Clarke/Frederick counties

FOSR 2019 Summer Quantitative E. coli Concentration Results through 07.02.2019

The following are recommendations from the Virginia Department of Health to help prevent illness and injury when swimming in natural waters:

  1. Avoid swimming in natural waters for a few days after a heavy rain event.
  2. Avoid swallowing water when swimming.
  3. Avoid getting water shot up your nose when swimming, especially in warm shallow water.
  4. Avoid swimming or wading in with open wounds or cuts.
  5. Look for posted signs near the swimming area.
  6. Don’t swim in areas where there are dead fish present.
  7. Don’t swim if you are ill.
  8. Shower with soap and clean water after swimming.
  9. Avoid swimming in muddy water of lakes, ponds, and rivers.
  10. Avoid swimming in unfamiliar ponds, streams, creeks, ditches, and canals.
  11. Be aware of local weather conditions prior to recreational activities and watch for dangerous waves and signs of rip currents.
