Borehole geophysical data from Eastland Woolen Mill Superfund site, Corinna, Maine, March 1999

Borehole-geophysical data were collected in cooperation with the U.S. Environmental Protection Agency in seven bedrock wells at the Eastland Woolen Mill Superfund site, Penobscot County, Corinna, Maine, in March, 1999. The data were collected as part of a reconnaissance investigation to provide information needed to address concerns about the distribution and fate of contaminants in ground-water at the site. The borehole geophysical data were also needed to guide subsequent data collection associated with the development of a remediation workplan. The borehole geophysical logs collected included: natural gamma, caliper, fluid temperature, fluid conductivity, electromagnetic conductivity, electromagnetic resistivity, spontaneous potential, and single-point resistivity.

Hydrologic data from the Johnson Brook phosphorus loading study, Kennebec County, Maine

Streamflow, water quality, and precipitation data collected during the 1980 and 1981 water years are reported. The purpose was to document changes in total phosphorus loads resulting from a change in agricultural waste management practices in the Johnson Brook watershed in Maine. Streamflow data include mean-daily discharges for the period May 12, 1980, through September 30, 1981, and instantaneous discharges determined during water quality sampling. Water quality data for the period March 1980 to September 1981 include total phosphorus concentrations determined from samples collected using cross-sectional depth-integrating sampling techniques and from samples collected using a pumping sampler. Suspended sediment concentrations, and water temperature and specific conductance values are also included. The precipitation data are daily totals for the period October 1980 through September 1981.

Time-of-travel studies for the Little Androscoggin River, Maine

Time-of-travel studies were conducted at flow durations of 20, 80, and 95 percent on the Little Androscoggin River from South Paris to Auburn, Maine. The river is about 29.3 miles long, and drains an area of about 354 square miles at its mouth. Traveltimes were determined by tracing the movement of rhodamine WI, a soluble fluorescent dye. The dye was injected into the river at the upstream end of each reach studied and water samples were collected at the downstream end of the study reach and analyzed for dye concentrations. Time-of-travel data were related to stream discharge to estimate traveltime for a water-soluble contaminant traveling between any two points at any discharge in the low-to-high flow range. The discharges of the Little Androscoggin River at the time of the study ranged from 40 to 950 cubic feet per second at the Auburn gaging station. Traveltimes from South Paris to Auburn, Maine, ranged from 51 to 648 hours.
