Hydrogeology and water quality of significant sand and gravel aquifers in parts of Androscoggin, Cumberland, Franklin, Kennebec, Lincoln, Oxford, Sagadahoc, and Somerset Counties, Maine: Sand and gravel aquifer maps 10, 11, 16, 17 and 32
A reconnaissance level geohydrologic study was made of 2,408 sq mi in Androscoggin, Cumberland, Franklin, Kennebec, Lincoln, Oxford, Sagadahoc and Somerset Counties in Maine. This area is included in Maps 10, 11, 16, 17, and 32 of the Sand and Gravel Aquifer Map Series published by the Maine Geological Survey. The significant sand and gravel aquifers, consist of glacial ice-contact and outwash deposits which occur primarily in the valleys of the major rivers and along their tributaries. Significant aquifers comprise almost 109 sq mi, but yields that exceed 50 gal/min are estimated to be available within only 21% of this area. Typically, the water table is within 20 ft of the land surface. Based on seismic data, the great known depth to bedrock is 340 ft. The regional groundwater quality has the following characteristics: It is slightly acidic to slightly basic; calcium and sodium are the most abundant cations; bicarbonate is the most abundant anion; and the water is soft. In some localities concentrations of iron and manganese are high enough to limit use of the water without treatment. Sixty-six sites, including 32 solid waste facilities and 18 salt-storage lots were identified as potential sources of groundwater contamination to the sand and gravel aquifers in the study area. 79 refs., 11 figs., 9 tabs.
