"This county map is taken from the statewide map, "Aquifer sensitivity to contamination by pesticide leaching in Illinois," Illinois State Geological Survey (ISGS) Open File Series 1995-5S."
"This county map is to be used in conjunction with ISGS Environmental Geology 148, the report that discusses the map development and recommended uses."
"The accuracy of this map is insufficient for evaluating aquifer sensitivity to contamination by pesticides at specific points. It is the responsibility of the user to determine the appropriateness of this map for specific applications."
