Current Site Status
Nazcon Concrete cleaned up this site under an EPA order. No further EPA involvement at the site is warranted at this time.
The Site is located at 1160-A Spruce Avenue in the Beltsville Industrial Park, Beltsville, MD. NAZCON Inc, a ready mix concrete company, dumped undelivered concrete and rinse water into a series of settling ponds. The precipitant solution was then discharged into the Indian Creek, which runs into the Anacostia River.
- Site Responsibility
- Cleanup of this Site is the responsibility of Federal and State governments, and NAZCON Inc., a Potentially Responsible Party (PRP), under an EPA Superfund Removal Order.
- NPL Listing History
- This Site is not on the National Priorities List.
Threats and Contaminants
The precipitant is a calcium carbonate caustic (i.e., high pH), and a characteristic hazardous waste.
The Washington Sanitary Sewer Commission detected high pH readings in the Indian Creek and notified EPA's Criminal Investigation Division (CID) on September 3, 1998. On September 4, 1998, EPA plugged the conduit connecting the pond and Creek, preventing further discharge. On September 30, 1998 NAZCON signed an Administrative Order to perform Site cleanup and closure to achieve all federal requirements.
