Description:

Ground water pollution potential maps represent a measure of the relative susceptibility of an area to pollution of the ground water. Factors such as depth to water, net recharge, aquifer media, soil media, topography, impact of the vadose zone media, and hydraulic conductivity of the aquifer are given a numeric rating and a composite index is developed. This index is called the ground water pollution potential (GWPP) index. A high GWPP index indicates a high potential for pollution of the ground water. For additional information see Ground Water Pollution Potential of Franklin County, Ohio, 1995, Report No. 40, Ohio Department of Natural Resources, Division of Water. (Description extracted from O.D.N.R. Metadata)

Intent:

To establish the susceptibility of areas to ground water pollution and to identify these areas as having characteristics worth protecting as development continues throughout the study bounds.

Analysis Summary:

The ground water pollution potential data layers were downloaded for the study bounds, combined into one data layer, and recoded for this study in relation to their designated GWPP. The colors of the various rankings are shown in a range from green (being the most susceptible to ground water pollution) to red (having the least potential for ground water pollution). Those areas having the highest potential for ground water pollution were coded to designate the areas as being the most critical to protect against development and thus being areas critical to protecting as a natural resource area.
