Estimates of future high, median, and low ground- water levels are needed for engineering and architectural design decisions and for appropriate selection of land uses. For example, the failure of individual underground sewage-disposal systems due to high ground-water levels can be prevented if accurate water-level estimates are available. Estimates of extreme or average conditions are...

Water-use data collected in Rhode Island by different State agencies or maintained by different public suppliers and wastewater- treatment facilities need to be integrated if these data are to be used in making water- resource management decisions. Water-use data for the town of Cumberland, a small area in northeastern Rhode Island, were compiled and integrated to provide an example of...

Potential public water-supply areas of the Cape Cod aquifer, Massachusetts, were identified using a geographic information system (GIS) to aid regional and local ground-water resource management efforts. Criteria were selected to identify potential areas on the basis of data restrictions in addition to State requirements for siting new public water- supply wells, Federal or local...

Estimated freshwater withdrawals during 1990 in New Hampshire totaled about 422 million gallons per day from ground-water and surface-water sources. The largest withdrawals were for thermoelectric-power generation (60 percent), public supply (23 percent), and industrial use (9 percent). Most withdrawals, 358 million gallons per day, were made from surface- water sources, as compared to...

An experiment was designed to evaluate the changing chemical composition of the water pumped from a well screened in a physically and chemically heterogenous aquifer. Well F453-63, at the U.S. Geological Survey Toxic-Substances Hydrology research site located on Cape Cod, Massachusetts, was selected because it was known that the screen penetrated both the oxic and anoxic zones of the...

The 72.4-square-mile Upper Wood River study area is in the Pawcatuck River basin in southern Rhode Island. Stratified drift is the only principal geologic unit capable of producing yields greater than 0.5 Mgal/d. Transmissivity of the aquifer ranges from 7,600 to 49,200 sq ft/d. Water-table conditions prevail and the aquifer is in good hydraulic connection with perennial streams and...

An investigation of the Quashnet River stream- aquifer system on Cape Cod was initiated in response to concern over possible streamflow reduction and degradation of the sea-run brown trout habitat of the river resulting from proposed ground-water withdrawals. A two-layer finite-difference ground-water-flow model was developed to simulate the stream-aquifer system. Steady-state pumping...

Activities associated with agricultural, residential, commercial, and industrial land uses have affected water quality in 4 stratified-drift aquifers in Connecticut. Water-quality data from 116 shallow wells were segregated by land use. Nonparametric statistical analysis indicate that 27 water-quality variables differ at the 0.05 significance level for samples from at least one land-use...

Measurement of the rate and direction of ground water flow beneath Wollaston Beach, Quincy, Massachusetts by use of a heat-pulsing flowmeter shows a mean velocity in the bulk sediment of 40 cm d−1. The estimated total discharge of ground water into Quincy Bay during October 1990 was 1324–2177 m3 d−1, a relatively low ground water discharge rate. The tides have only a moderate effect on...

The Panola Mountain Research Watershed (PMRW), located in the Panola Mountain State Conservation Park near Stockbridge, Georgia has been selected as a core research watershed under the Water, Energy and Biogeochemical Budgets (WEBB) research initiative of the U.S. Geological Survey (USGS) Global Climate Change Program. This research plan describes ongoing and planned research activities...
