DNREC Notice No. WHS20240247
Non-Discrimination Policy

The Department has adopted a plan regarding the clean-up of Operable Unit 5 (OU-5) of the Eden Hill Farm Site located in Dover. The Site was previously used as farmland. The remedial action was completed as an interim action and included excavating soils with elevated concentrations of arsenic in a select area of OU-5 to prevent unacceptable exposure to existing Site soils for future Site users. No additional remedial action for soils is necessary.

DNREC issued a public notice of the Proposed Plan for OU-5 of the Site on June 5, 2024. There were no comments or questions from the public regarding the Proposed Plan. Details of the Final Plan are available online at:
