What kinds of sites are in ECSI?
Sites in ECSI comprise a wide variety of sizes, locations, features, contaminant profiles, and degrees of Cleanup Program information. What all sites have in common is documented, suspected, or remediated hazardous substance contamination in groundwater, surface water, soil, or sediments. Some ECSI sites have minimal information available and need an initial evaluation, while others have completed investigative and remedial actions, and have earned a NFA decision from DEQ. Sites range from urban industrial complexes to isolated rural facilities contaminated by disposals or spills. Most sites are either industrial or commercial, but the Cleanup Program sometimes adds highly contaminated residential properties to ECSI.
