Is the sewage hazardous?
Avoid contact with untreated sewage, as it may carry bacteria and viruses. Sewage is made up of human waste, household chemicals, personal hygiene products, pharmaceuticals, and more. Untreated sewage can contain many pathogens, causing a variety of illnesses ranging from E. coli to hepatitis. If you believe you have come into contact with it, please do the following:
- Leave the area immediately.
- Wash exposed skin thoroughly with soap and clean water.
- Disinfect any affected areas or items.
- Do not consume food or water that may have been exposed.
- Seek medical attention if symptoms occur.
- Report exposure to DC Water at (202) 612-3400.

What are the environmental impacts of the sewage?
Currently, 60 million gallons of sewage are carried by the Potomac Interceptor every day. The sewer overflow is causing this sewage to enter the Potomac River and surrounding environment. Sewage contains a host of bacteria, nutrients, and chemicals that can cause dead zones, species loss, and degraded habitats. The change in water quality harms sensitive species that depend on clean water to survive.
