Division of Waste and Hazardous Substances

Published: Nov. 25, 2020

The Department has adopted a plan regarding the clean-up of the 518 S. Heald Street Site located in Southbridge, Wilmington. The Site has had various commercial uses dating back to the 1930s with a former limousine storage and repair facility being the most recent known use. The Site requires a restriction on use of groundwater at the Site, capping of contaminated soils, and long-term monitoring to ensure prevention of exposure to existing Site soils and groundwater for future Site users.

DNREC issued a public notice of the Proposed Plan for 518 S. Heald Street Site on October 21, 2020. There were no comments or questions from the public regarding the Proposed Plan. Details of the Final Plan are available at the office of DNREC-RS (391 Lukens Drive, New Castle, DE, 19720) and online at:
