Horsepen Creek is one of the streams that flow into the Potomac River and then into the Chesapeake Bay. Horsepen Creek lies in Fairfax County, Virginia, a major county in Northern Virginia on the U.S. East Coast.
The water in Horsepen Creek is listed by the Environmental Protection Agency as containing fecal coliforms, although not in a great enough quantity to dangerously increase the likelihood of pathogens being present. According to the report, the levels of fecal coliforms must not be allowed to reach 200 colony-forming units per 100ml in the summer or 1000 colony-forming units per 100ml in the winter.
Horsepen Creek and Sugarland Run are part of a Watershed Restoration Level II Area, with the condition of Horsepen Creek ranging from fair to very poor. This is because of the poor habitat provided, both for land animals and for fish.

A fecal coliform is a facultatively anaerobic, rod-shaped, gram-negative, non-sporulating bacterium. Coliform bacteria generally originate in the intestines of warm-blooded animals. Fecal coliforms are capable of growth in the presence of bile salts or similar surface agents, are oxidase negative, and produce acid and gas from lactose within 48 hours at 44 ± 0.5°C. The term thermotolerant coliform is more correct and is gaining acceptance over "fecal coliform".
