In 2020, CEI conducted a Phase II Environmental Investigation based on findings and identified data gaps CEI identified as part of an Environmental Condition of Property (ECP) report completed for the U.S. Army Corps of Engineers and the U.S. Army. The project objective included:
- Assessing whether there has been a release of hazardous substances within the requirements of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA),
- Developing further information on the presence of substances not previously identified, and
- Providing information on the target analytes that may pose risk to human health or the environment.
As part of the field investigation preparation CEI completed approved work plans that included a comprehensive Health and Safety Plan (HASP) (Site Safety and Health Plan, Accident Prevention Plan and Activity Hazard Analysis) and Uniform Federal Policy – Quality Assurance Project Plan.
Field investigation activities included the following:
- Soil boring and sediment sampling with soil sampling and analysis for VOCs, VPH, EPH, PCBs, metals and explosives;
- Groundwater well installation, development and sampling including VOCs, VPH, EPH, metals and explosives;
- Transect surface soil sampling for arsenic; and
- Hazardous building material investigation focusing on asbestos, PCBs, and lead;
CEI’s Phase II recommendations will be considered and a Finding of Suitability to Transfer (FOST) developed as part of a separate Task Order.
