CERCLA Cleanup Projects

The Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) process assesses site conditions, evaluates hazards to humans and the natural environment, determines the level of cleanup required and selects an appropriate cleanup alternative.

Projects on this list have been or currently are being investigated for potential human health and environmental impacts. Various stages are represented, including Investigation (Abbreviated Preliminary Assessment, Site Inspection), Alternative Evaluation (Risk Assessment, Engineering Evaluation/Cost Analysis) and Cleanup (Removal Action). Progression through the stages depends on findings and recommendations from the preceding stage. Each project contains all available documents.
