WASA Warns Against Unsolicited Tap Water Testing

August 01, 2007

It has come to the attention of the District of Columbia Water and Sewer Authority (WASA) that residents in the District are receiving unsolicited water testing kits, in a clear door hanger, from a company or organization offering to test their tap water. These solicitations are not sanctioned nor endorsed by WASA. The company or organization does not identify themselves nor do they provide contact information.

The drinking water that WASA distributes to homes, businesses and more than 500,000 citizens in the District of Columbia is in full compliance with federal Safe Drinking Water Act regulations for health and safety. Customers with concerns or questions about the quality of their tap water should contact the WASA Water Quality Division, Monday through Friday, 8 a.m. to 5 p.m. at 202-612-3440 or e-mail waterquality@dcwasa.com.

Graphic with the information for the Community Meeting

As DC Water continues repair efforts on the Potomac Interceptor sewer line, we want to provide an opportunity for the community to engage with us on Wednesday, February 25, to ask questions, and learn more about the response, impacts to the Potomac River, and next steps in the emergency repair and long-term rehabilitation efforts.

Trench box being installed to expand excavated area

Repairs are moving forward, with crews closer to reaching a debris dam and large rocks blocking a section of the damaged Potomac Interceptor. Work has been completed to fully extend the excavation site and install trench boxes to stabilize and isolate the additional pipe sections. No overflows entering the Potomac River have occurred in 16 days.

The excavation around a damaged section of the Potomac Interceptor has been extended and trench boxes installed to provide shoring and stability. This doubles the size of the excavated area, to connect the collapse site with a downstream access point to the Potomac Interceptor.
