Note: This dataset is updated daily. The Known Contaminated Sites List for New Jersey (KCSLNJ) are those sites and properties within the state where contamination of soil or ground water has been confirmed at levels equal to or greater than applicable standards. This list of Known Contaminated Sites may include sites where remediation is either currently under way, required but not yet initiated or has been completed and addressed via an Institutional Control. The KCSLNJ layer has now been modified such that the information portrayed in the GIS layer is updated daily through a SQL query of NJEMS/Masterfile, which allows for a dynamic KCSLNJ layer. This is critical for the general public and SRP regulated community by allowing them to see the most up to date information for a known contaminated site in a GIS format via the following web mapping applications: NJ Geoweb (https://www.arcgis.com/apps/webappviewer/index.html?id=02251e521d97454aabadfd8cf168e44d) or the SRP Profile in ArcGIS Online (AGO) (https://njdep.maps.arcgis.com/apps/webappviewer/index.html?id=25d1cd0ae75048b1a7867971392b6995).

This data layer identifies those Known Contaminated Sites (KCS) or sites on Site Remediation Programs' (SRP) Comprehensive Site List (CSL) that have been assigned a Deed Notice. A deed notice is described by NJ State Legislature (NJSA 58:10B-13a) as a "...notice to inform prospective holders of an interest in the property that contamination exists on the property at a level that may statutorily restrict certain uses of, or access to, all or part of that property, a delineation of those restrictions, a description of all specific engineering or institutional controls at the property that exist and that shall be maintained in order to prevent exposure to contaminants remaining on the property, and the written consent to the notice by the owner of the property".

New Jersey is home to the largest number of hazardous waste sites – or Superfund sites – across the United States, with *** locations as of March 2025. California and Pennsylvania followed, each with over ** sites at the time. What is a Superfund site? In 1980, the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) was passed, which allowed the Environmental Protection Agency to clean up the most contaminated sites in the United States. The locations managed under this program are commonly known as Superfund sites and include hazardous waste sites such as landfills and mines, where toxic waste has been dumped. As of March 2025, ***** Superfund sites across the ** U.S. states were listed on the National Priorities List (NPL). Hazardous waste shipments within the U.S. Featuring the sixth-highest number of hazardous waste sites across the United States, Texas received the largest volume of hazardous waste from other states in recent years, at nearly ******* metric tons. The southern state was also the largest shipper of hazardous waste within the North American country, with outbound shipments surpassing inbound by some *********** metric tons.

The Site Remediation Program (SRP) - Preferred ID points represent both active and closed sites within SRP for which locational coordinates are available. These sites include all sites that are regulated under the Site Remediation Reform Act (SRRA), N.J.S.A. 58:10C-1 et seq. The NJDEP New Jersey Environmental Management System (NJEMS) serves as the database that supplies the coordinates and descriptive attributes from several tables used to generate this GIS layer. This layer is produced primarily for the NJDEP's online interactive mapping web applications (NJ-GeoWeb) and ArcGIS users. The original location for the SRP Preferred ID is generated on a nightly cycle from the NJEMS (Masterfile) SRP preferred ID coordinates. Two related table, one which identifies the LSRP associated with a specific case activity and the second of which identifies information about the activities for a given case are also generated on a nightly cycle via SQL querying of the same database systems.Users should note that not every SRP preferred ID in NJEMS has an established coordinate (GPS or otherwise). NJDEP is continually working to acquire these with GPS, location data submitted to permitting programs, and through address matching techniques. SRP also continues to evaluate and refine existing case locations based on both staff input and input from the regulated community.

This application was designed to allow for easy access to information associated with the Contaminated Site Remediation & Redevelopment (CSRR) Known Contaminated Sites List (KCSL) GIS layer through a customized pop-up and a link to run a dataminer report that provides a detailed site summary for a particular KCSL site. Additional CSRR GIS layers included in the web map and accessible through this application include the following:Site Remediation Program Preferred ID SitesGroundwater Contamination Classification Exception Areas (CEAs)Deed Notice AreasNJ Statewide Parcel LayerMunicipal Boundaries of New JerseyCounty Boundaries of New JerseyIn addition, a dashboard is provided that includes statistics gleaned from the KCSL and Site Remediation Program Preferred ID Sites at the state, county and municipal level as well as information regarding various aspects of the CSRR program.

This dataset summarizes multiple other environmental datasets at a municipal level. The summary level data acts as indicators to describe how the municipality is doing compared to the rest of the state and respective county. Additionally, several demographic indicators are included. The full list of indicators in this dataset include population, poverty, minority, uninsured, community drinking water exceedances, private well testing act summary data, groundwater and soil deed restrictions, surface water quality, urban land cover flooded, air permit sources, combined sewer overflows, brownfield development areas, contaminated sites, scrap metal facilities, age of housing, radon, open space, & traffic.

The "Brownfield and Contaminated Site Remediation Act" (N.J.S.A. 58:10B-1 et seq.) requires the Department of Environmental Protection to map regions of the state where large areas of historic fill exist and make this information available to the public. This GIS layer depicts areas of historic fill covering more than approximately 5 acres. For the purposes of this layer, historic fill, as defined at N.J.A.C. 7:26E-1.8, means, “non-indigenous material, deposited to raise the topographic elevation of the site, which was contaminated prior to emplacement, and is in no way connected with the operations at the location of emplacement and which includes, without limitation, construction debris, dredge spoils, incinerator residue, demolition debris, fly ash, or nonhazardous solid waste. Historic fill material does not include any material that is substantially chromate chemical production waste or any other chemical production waste or waste from processing of metal or mineral ores, residues, slag or tailings. In addition, historic fill material does not include a municipal solid waste landfill site.” The information in the layer makes no determination whether the material was contaminated prior to emplacement. This layer can be used as one line of evidence for an investigator’s professional judgment in determining that historic fill is present at a site; however, an investigation must still be completed in accordance with the Technical Requirements for Site Remediation at N.J.A.C. 7:26E-4.7. Also see the Historic Fill Technical Guidance for more information regarding the investigation and remediation of historic fill at: https://dep.nj.gov/srp/guidance/. This data was mapped at a scale of 1:24,000 (1 inch represents 2000 feet) and is not intended for use at more-detailed scales. Fill was mapped from stereo aerial photography taken in March 1979, supplemented in places by planimetric aerial photography taken in the spring of 1991 and 1992. Additional areas of fill were mapped by comparing areas of swamp, marsh, and floodplain shown on archival topographic and geologic maps on file at the N. J. Geological Survey, dated between 1840 and 1910, to their modern extent. In a few places, fill was mapped from field observations and from drillers’ logs of wells and borings. Most urban and suburban areas are underlain by a discontinuous layer of excavated indigenous soil mixed with varying amounts of non-indigenous material. This material generally does not meet the definition of historic fill and is not depicted on this map. Also, there may be historic fills that are not detectable on aerial photography or by archival map interpretation and so are not shown on this map, particularly along streams in urban and suburban areas. As of this January 2016 edition, twelve new quadrangles were added to the statewide coverage. They are Allentown, Beverly-Frankford, Brookville, Canton-Taylors Bridge, Chatsworth, Forked River- Barnegat Light, Indian Mills, Keswick Grove, Lambertville, Millville, and Woodmansie. As of this March 2025 edition, eight new quadrangles were added to the statewide coverage. They were Cassville, Lakehurst, Oswego Lake, Jenkins, Atsion, Bridgeton, Whiting, and Lakewood. Seven quadrangles have been revised. They are Trenton East, Trenton West, Pennington, Lambertville, Rocky Hill, Ship Bottom, Point Pleasant, and Califon.

This customized web mapping application has been developed for the New Jersey well drilling community. The Well Driller profile provides the mapped layers and tools to allow well drillers to find a location or area of interest, determine if the location is in or near the New Jersey Highlands or Pinelands areas, view possible groundwater contamination concerns in the area, measure distances between locations and determine the New Jersey state plane coordinates for Well Permit Applications.Click here to contact us

This is a graphical representation of the outline boundary for Brownfield Development Areas (BDA) in New Jersey.The data included in the layer enables GIS to map, as polygons, all current BDA's in New Jersey. A brownfield is any former or current commercial or industrial site that is currently vacant or underutilized and on which there has been, or there is suspected to have been, a discharge of contamination. Under the BDA approach, NJDEP works with selected communities affected by multiple brownfields to design and implement remediation and reuse plans for these properties simultaneously. The BDA approach enables remediation and reuse to occur in a coordinated fashion. In the process, we invite the various stakeholders, including owners of contaminated properties, potentially responsible parties, developers, community groups, technical experts for the local government and residents, and residents themselves, to participate in this cleanup and revitalization approach.

This data is a graphical representation of the listing of licensed active child care centers in NJ. It was created for the State of New Jersey's initiative regarding child care centers near contaminated sites. The Child Care Centers GIS layer contains all active, licensed child care facilities within the State of New Jersey based on a spreadsheet provided to the NJDEP Site Remediation Waste Management Program (SRWMP) by the New Jersey Department of Children and Families (NJDCF) Office of Licensing. This monthly report also includes facilities operating in public schools (FOIPS) although these facilities are not required in most cases to submit environmental data to the NJDEP for NJDCF licensing. Proposed child care centers are not listed until a NJDCF License number is issued. ADVISORY: This data was created only to be used as guidance to find active child care centers. The data should not be used as the determining factor in conducting receptor evaluations and the actions taken to protect them. The child care data will be updated on a monthly basis as monthly updates of active child care facilities operation in New Jersey are provided to the NJDEP SRWMP by the NJDCF Office of Licensing. Users are hereby notified that data on NJDEP mapping applications for this data set may be more current than any downloadable shapefile, if provided.

This dataset provides information on Environmental and Public Health Stressors for each block group in New Jersey to help implement the New Jersey Environmental Justice Law codified at N.J.S.A. 13:1D-157 et seq (EJ Law). Under the EJ Law “Environmental or public health stressors” means sources of environmental pollution, including, but not limited to, concentrated areas of air pollution, mobile sources of air pollution, contaminated sites, transfer stations or other solid waste facilities, recycling facilities, scrap yards, and point-sources of water pollution including, but not limited to, water pollution from facilities or combined sewer overflows; or conditions that may cause potential public health impacts, including, but not limited to, asthma, cancer, elevated blood lead levels, cardiovascular disease, and developmental problems in the overburdened community (OBC). The New Jersey Department of Environmental Protection (Department) has developed data for 26 individual stressors within these categories and a Combined Stressor Total, which is the sum of adverse stressors in each block group.

The data included in the layer enables GIS to map, as polygons, the extents of tax parcels that constitute sites within Brownfield Development Areas (BDAs) in New Jersey. A brownfield is any former or current commercial or industrial site that is currently vacant or underutilized and on which there has been, or there is suspected to be, contamination from a discharge. Under the BDA approach, NJDEP works with selected communities affected by multiple brownfield sites to design and implement remediation and reuse plans for these properties simultaneously. In this way, remediation and reuse occur in a coordinated fashion that invites various stakeholders, including residents and community groups, owners of contaminated properties, potentially responsible parties, developers, and technical experts for the local government to participate in the BDA cleanup and revitalization approach.

This data identifies those sites where groundwater contamination has been identified and, where appropriate, the NJDEP has established a Classification Exception Area (CEA) in accordance with N.J.A.C. 7:9-1.6 and 1.9(b). CEAs are institutional controls in geographically defined areas within which the New Jersey Ground Water Quality Standards (NJGWQS) for specific contaminants have been exceeded. CEAs are established in order to provide notice that the constituent standards for a given aquifer classification are not or will not be met in a localized area due to natural water quality or anthropogenic influences, and that designated aquifer uses are suspended in the affected area for the term of the CEA. For further information about Classification Exception Areas: https://www.nj.gov/dep/srp/guidance/cea/cea_guide.htm
