Glacial aquifer systems in the northeastern United States; a plan for study

The U.S. Geological Survey project designed to study the availability and quality of water in glacial aquifers in the States of Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, and Ohio is scheduled for completion in 1986. It will focus on general principles that define aquifer geometry, hydraulic properties of sediments, recharge, discharge, physical-chemical properties of water, rock and water-rock interactions, and mechanisms for mixing of water from multiple sources. Planned project activities include compilation and analysis of available data for a regionwide analysis of glacial-aquifer systems, studies of selected system components such as recharge and chemical processes, classification of aquifers with regard to water-supply potential, and construction of generalized ground-water models to predict responses of types of aquifer systems to pumping and climatic stress. This report describes the general characteristics of glacial aquifer systems in the Northeastern United States and of planned work elements of the study. (USGS)

Water resources inventory of northwest Florida

Water resources of the 16 counties of the northwest Florida appear adequate unitl at least 2020. In the 4 westernmost counties, the sand-and-gravel aquifer and streams combined could provide 2,200 to 3,600 million gallons per day of water. Streams outside these counties could provide 5,600 million gallons per day. The Floridan aquifer could provide 220 million gallons per day. Generally, water of quality suitable for most purposes is available throughout the area, although water in smaller streams and in the sand-and-gravel aquifer is acidic and locally contains excessive iron. Water in the upper part of the Floridan aquifer is generally fresh, but saline at depth and in some coastal areas. The quantity of water available in the study area is about 8,020 to 9,420 million gallons per day and projected needs for the year 2020 range from 2,520 to 4,130 million gallons per day. ' Approximate method ' flood-prone area maps cover most of the area. (Woodard-USGS)
