SWAP Susceptibility Application
Project Title: SWAP Susceptibility Application
An application will be developed to integrate GIS and database processing steps for conducting public supply susceptibility assessments. The application will be configured to operate on NJDEP computers, and NJDEP personnel will be trained in its use.
Statement of Problem
NJDEP plans to continue conducting and revising assessments of the susceptibility of public supply wells and intakes to contaminants of concern. These contaminants include pathogens, inorganics, nutrients, pesticides, volatile organic compounds (VOCs), disinfection byproduct (DBP) precursors, and radionuclides. These contaminants are of concern because of their potential toxic, carcinogenic, or other health effects, costs of monitoring and treatment, and lack of understanding of their origins and transport. The results of these assessments may be used by NJDEP to suggest waivers for chemical analysis to reduce monitoring costs for supplies that may be of low susceptibility.
As part of the New Jersey Source Water Assessment Program, the U.S. Geological Survey previously developed models to determine the susceptibility of surface water intakes and groundwater supply wells used for public supply. Applying these models presently requires a substantial data-processing effort involving many manual steps. An adaptable, automated process is needed so that NJDEP can update and apply susceptibility models to public supply wells and intakes.
Strategy and Approach
An application will be developed that the Bureau of Safe Drinking Water can use to generate groundwater and surface water assessments efficiently and independently. The application will utilize ArcInfo Workstation and Microsoft Access 2000.
