NJDEP, Site Remediation & Waste Management Program (SRWMP), Office of Brownfield and Community RevitalizationThe Brownfield Inventory is a subset of sites from the Known Contaminated Sites List (KCSL) for New Jersey. The Office of Brownfield & Community Revitalization staff vetted and determined each site on the Brownfield Inventory to be a brownfield site. As defined by the USEPA, a brownfield site is "real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant." In other words, brownfield sites are abandoned, idled, or underused industrial and commercial facilities where expansion or redevelopment is complicated by real or perceived environmental contamination. This inventory exclusively looks at non-residential properties. While the KCSL dataset is updated daily, the Brownfield Inventory is updated on an as-needed basis. Phase 1 of the Brownfield Inventory exclusively includes brownfield sites in Opportunity Zones in Community Collaborative Initiative municipalities. Phase 2 of the Brownfield Inventory includes all brownfield sites within Community Collaborative Initiative municipalities. Future phases will expand upon this work.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/a895bf0512044349bc6631b64457a33f_36engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicBrownfield Inventory for New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2025-09-24
