The Department of Natural Resources and Environmental Control (DNREC) Remediation Section (RS) has adopted a plan regarding the clean-up of Operable Unit 11 (OU-11) Battery Elder on the Fort Dupont Redevelopment [DE-1618] Site (Site) located in Delaware City. OU-11 is one of the Operable Units (OUs) within the over 300-acre Fort Dupont Site. No redevelopment is planned for OU-11 and it will remain part of the Fort Dupont State Park. The Site requires the submittal of a Remedial Action Work Plan which includes the removal and disposal of lead-impacted soils to meet DNREC Hazardous Substance Cleanup Act (HSCA) Standards; development of a contaminated materials management plan (CMMP); close and abandon the monitoring wells in accordance with state and local regulations; and the recording of an Environmental Covenant to restrict the Site to non-residential use, limit groundwater withdrawal, and require vapor intrusion assessment of any new structures, and compliance with the CMMP; as well as the submittal of a Remedial Action Completion Report.

DNREC issued a public notice of the Proposed Plan of Remedial Action (Proposed Plan) for OU-11 Battery Elder on the Fort Dupont Redevelopment Site on November 12, 2025. There were no comments or questions from the public regarding the Proposed Plan.

Details of the Final Plan of Remedial Action are available online at den.dnrec.delaware.gov.
