DGS97-1 Public-Community Water-Supply Wells of New Jersey



The Public-Community Water-Supply (PCWS) Wells is an ESRI Geographic Information System (GIS) point shapefile with associated Microsoft Access™ relational database. It contains information for the wells in New Jersey that supply potable water to public communities. The NJDEP has cataloged and field located, using the Global Positioning System (GPS), the PCWS wells as part of the Source Water Area delineation process. (Updated 7-11-2011)

The public community water supply (PCWS) layer was removed until a secure web portal is developed.

The PCWS data are sensitive in nature. Currently, these data are distributed only to those entities which can demonstrate a need for the data and guarantee data confidentiality.  To gain access to the PCWS data send a written request with the following information:

5. Provide a description of existing protocols which address handling and storage procedures to protect the information from unauthorized access of computer or written records.  Specifically address provisions for the following:

         a. Protection of electronic files (containing sensitive information) on protected servers, with appropriate cyber security features, such as firewalls, intrusion detection, etc.;
          b. Protection of paper files (containing sensitive information) in designated storage areas;
         c. Access controls in place which limit access to only those staff/employees who necessitate the use of the information as part of their scope of work; and
