Hydrologic data for the Eastland Woolen Mill Superfund Site, Penobscot County, Corinna, Maine, March through June 1999 Hydrologic data for the Eastland Woolen Mill Superfund Site, Penobscot County, Corinna, Maine, March through June 1999
Hydrologic data were collected at the Eastland Woolen Mill Superfund Site, Corinna, Maine, from March 19, 1999 through June 11, 1999 as part of a study to formulate a geologic characterization and conceptual model of this study area. Data-collection consisted of measurements of water-surface elevations at 7 surface-water sites and 20 wells.

Methyl tert-Butyl Ether (MTBE) in ground water, air, and precipitation at North Windham, Maine Methyl tert-Butyl Ether (MTBE) in ground water, air, and precipitation at North Windham, Maine
Thirty-one monitoring wells in the Windham aquifer in North Windham, Maine, were sampled for methyl tert-butyl ether (MTBE) from July 1998 to May 1999. MTBE was detected in 35 percent of the wells sampled in the Windham aquifer. MTBE was detected in 64 percent of wells in the high-yielding part of the aquifer; these wells account for 82 percent of all wells with detectable MTBE. Land...

Water-quality assessment of the New England coastal basins in Maine, Massachusetts, New Hampshire, and Rhode Island: Environmental settings and implications for water quality and aquatic biota Water-quality assessment of the New England coastal basins in Maine, Massachusetts, New Hampshire, and Rhode Island: Environmental settings and implications for water quality and aquatic biota
The New England Coastal Basins in Maine, Massachusetts, New Hampshire, and Rhode Island constitute one of 59 study units selected for water-quality assessment as part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) program. England Coastal Basins study unit encompasses the fresh surface waters and ground waters in a 23,000 square-mile area that drains to the...

Relation of arsenic, iron, and manganese in ground water to aquifer type, bedrock lithogeochemistry, and land use in the New England coastal basins Relation of arsenic, iron, and manganese in ground water to aquifer type, bedrock lithogeochemistry, and land use in the New England coastal basins
In a study of arsenic concentrations in public-supply wells in the New England Coastal Basins, concentrations at or above 0.005 mg/L (milligrams per liter) were detected in more samples of water from wells completed in bedrock (25 percent of all samples) than in water from wells completed in stratified drift (7.5 percent of all samples). Iron and manganese were detected (at...
