A Washington Post article (2016-05-05) reported that a wastewater treatment plant in Prince George’s County contained a 1.5 million gallon spill of partially treated sewage on the plant’s grounds. From the article:
No sewage reached any storm drains or waterways, said Luis Maya, a spokesman for the Washington Suburban Sanitary Commission (WSSC), which provides water and sewer services in Prince George’s and Montgomery counties.
Maya said the spill was contained on the site of the Piscataway Wastewater Treatment Plant in Accokeek. Maya said the sewage had already gone through the first step in the treatment process. The spill, he said, occurred when workers tried to change the flow of the sewage during a construction project underway at the plant.
The article noted that the WSSC had notified both the Maryland Department of the Environment and the Prince George’s County Health Department.
