A major infrastructure failure recently resulted in a massive discharge of wastewater into the Potomac River northwest of Washington, D.C. A 72-inch sewer pipe collapsed, spilling wastewater from the ground and causing an estimated overflow of 40 mgd.
Meanwhile, the Potomac Riverkeeper Network released the results of its testing of contaminated water from the sewage spill along the Potomac and the environmental group's data shows contamination which is nearly 12,000 times what authorities limit for human contact. The PRN also estimates that almost 300 million gallons have entered the Potomac River.
