The goal of this document is to help delineate the approximate capture zones for springs and public water-supply wells in karst aquifers of the Ridge and Valley and Appalachian Plateaus Physiographic Provinces. These Rules of Thumb (RTs) are relatively low-cost approaches that can be used by ground-water technical personnel, and which are likely to be more accurate than fixed-radius methods. The initial intent of the US Environmental Protection Agency (EPA) was to develop RTs applicable to all karst areas in the US, but regional differences among karst settings limit the RTs described here to the Appalachians. This document is written for ground-water technical professionals in agencies that implement either the state Wellhead Protection Program (WHPP) or the Source Water Assessment and Protection Program (SWAPP), or those who are interested in supporting the goals of these programs. With the aid of ground-water technical professionals, this document can also be used by those with no technical background.
