||The purpose of this document is to serve as a guidebook for conducting Groundwater Protection Needs Assessments (GPNA). The intent of a GPNA is to provide a comprehensive evaluation of the groundwater protection measures necessary in order to assure a long-term supply of potable water that is not highly vulnerable to contamination. The Illinois Environmental Protection Agency (IEPA), the Illinois State Geological Survey (ISGS) and the Illinois State Water Survey (ISWS) have developed the approach discussed for undertaking of GPNA.
