Heating Oil Spill
January 6, 2021

Alert neighbors in the Country Club Hills neighborhood of Fairfax City reported an oily sheen, chemical odor, and discolored water in Accotink Creek. Fairfax City Fire Marshal responded. The marshals determined fuel oil contamination was coming from a storm drain outfall just downstream from Chain Bridge Road. The marshals deployed a boom to block further contamination of the creek. The search for the source back through the network of storm drains revealed a leaking heating fuel tank. Remediation and penalty details may become available later. Neighbors, be alert for signs of fish and aquatic wildlife die-off. [Marshal's Incident report E210061350, DEQ Incident Report207927]

The main source of the discoloration was further upstream, at the Paul VI construction site, where sediment-laden water was being discharged from filter bags - an issue not sufficient to interest enforcement agencies. These filter bags function to reduce, but not eliminate, the sediment reaching streams from bare soil construction runoff. Even this lower amount of sediment adds up, coating the streambed and smothering much of the life that forms the base of the aquatic food chain.
