Process Description:
Most CKEs in the initial CKE GIS layer were mapped based on a series of NJDEP Immediate Concern Unit (ICU) binders that contained pertinent information about each CKE including a hard copy map that indicated the CKE, well restirction area (WRA) or ground water impact area (GWIA) boundary. These initial boundaries were created without the use of a NJ State-Wide GIS parcel layer so may not line up with property bounderies contained in the New Jersey statewide parcel layer. The majority of the hitoric CKE boundaries were refined based on the parcel layer, however, to the extent possible. Georeferencing of an electronic copy the hard copy map was also conducted to aid in refining the original CKE boundaries. Additional CKEs for active potable well IECs were also mapped based on information obtained through Spill Fund Claim data, NJDEP file reviews and/or attachments associated with the potable well IEC found in NJEMS.
