The technology of the Geographic Information Systems (GIS) is used to map the potential hazardous waste site locations within the southeastern portion of Newark, New Jersey and to assess the potential risks of such sites to both human and environmental health. The study site is a densely populated section of the Newark metropolitan area with high concentrations of industries, predominantly chemicals, oils and paints. Varieties of geospatial data in both digital and analog forms were input for GIS database development and proximity analysis was performed using a GIS software - Arc View. This pilot study provided a baseline integrated GIS system which proved to be a cost-effective tool in gaining detailed information on waste sites and their impacts on both ecosystem and human welfare.
