Geospatial Technology and Source Water Protection Measures for Small Public Water Systems
Mississippi State University; Southeast Regional Small Drinking Water Systems Technical Assistance Center
Various surface geology conditions and soil associations can be potentially hazardous to small water system wells and their wellhead protection areas. By using geographic information systems (GIS) layers, it is possible to determine these potential hazards. This report summarizes such a study in a small area of the state of Mississippi and details the GIS data layers that were obtained, the agency that crated the layers, and the ways in which the layers were analyzed.
