Northern Logan County Groundwater Monitoring
The Illinois State Water Survey (ISWS), under contract to the Northern Logan County Water Authority, continuously monitors five wells: SWS-E, SWS-10, SWS-08, MTH-22D, and MTH-22S. Two water levels are monitored at MTH-22, deep (labeled D) and shallow (labeled S). These four wells are part of the larger McTaz monitoring network, shown in the map.

Project Publications
Each year, the ISWS submits a letter report to sponsors and interested groups in the area. The letter contains hydrographs of each well, a summary of the information gathered to date, and some analysis of the data where findings warrant it.
