Layer: Known Contaminated Sites List (ID: 0)

Name: Known Contaminated Sites List

Display Field: PI_NAME

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: Note: This dataset is updated daily. The Known Contaminated Sites List (KCSNJ) for New Jersey 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. The KCSLNJ layer has now been modified such that the information portrayed in the GIS layer is updated on a daily basis through a SQL query of NJEMS/Masterfile. Generating the KCSL GIS layer on a daily basis via an SQL query allows for a dynamic KCSL 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 NJ Geoweb.A "live" KSCNJ report can also be viewed via Data Miner at: 1) Go to 2) Select Search by Category 3) Select Site Remediation then Submit 4) Under General, select The Known and Suspected Sites by County for a listing of Known Contaminated Sites by County. Information concerning individual contaminated sites can be viewed via other dataminer reports based on the Site ID or the SRP Preferred Interest # for the SRP case associated with that site. A small number of sites in the KCSL have no X/Y coordinates as of this date and therefore are not included in the GIS version. These sites do appear on the above in the tabular reports. Coordinates for the GIS version of the KSCL were largely "front door" locations acquired via "address matching" or which is an approximation of the facility front door. Many of these locations were also gathered by the Department using GPS and although these tend to be much more accurate, mistakes are sometimes made. Current protocol for assigning site locations defer to the center of the site or center of facility. Since errors can occur, users are encouraged to notify BIS of any these or any other inaccuracies in the KCSNJ through email to For guidance in how to report errors see the 'Supplemental Information' section below.
