Major-ion and isotopic analyses of ground water have been used to develop a conceptual model of flow and recharge to the Mahomet Bedrock Valley Aquifer (MVA). The MVA is composed of clean, permeable sands and gravels and forms a basal'' fill up to 60 m thick in a buried, west-trending bedrock valley. A thick succession of glacial tills, some containing interbedded lenses of sand and gravel, covers the MVA. Three regions within the MVA have hydrochemically distinct ground-water types. A fourth ground-water type was found at the confluence of the MVA and the Mackinaw Bedrock Valley Aquifer (MAK) to the west.
