This report is intended to provide both a basic understanding of groundwater resources in Christian County and links to more in-depth sources of information, maps, and data. Links are highlighted in blue and underlined. Most of the links are to documents or maps in Adobe PDF files. PDF files may be viewed with the free Acrobat Reader. Some of the files are large and, depending on your system, you may prefer to download the files to your system overnight. A few maps may be in MrSid file format. These files are viewable with the free MrSid Viewer, with ESRI geographic information system software, and with any other MrSid-compatible software.
