Has potential contamination from the Oily Waste Disposal Facility been characterized?

While the Oily Waste Disposal Facility (OWDF) is on the Red Hill property, this site is currently being investigated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Petroleum contamination at the OWDF was previously investigated and the extent and magnitude of petroleum contamination in soil and groundwater largely determined. However, recent detections of PFAS in groundwater at the OWDF and in the vicinity of Red Hill Shaft has led regulators to request the Navy conduct a PFAS investigation on and around the OWDF. Regulators will require the Navy to include contaminants from all sources when they evaluate risk and choose remediation methods. The Navy committed to providing a work plan for the investigation in early 2026.
