Availability of water from aquifers in upstate New York
Two maps give the locations and estimated yields of unconsolidated and bedrock aquifers of upstate New York, excluding Long Island. The map of surficial deposits give estimates of well yield, aquifer yield, and specific capacity; the map of bedrock units gives the same information and also delineates areas in which induced infiltration from streams into the bedrock and unconsolidated aquifers is possible. The maps are designed to assist planners in managing ground-water supplies. The maps represent data that were compiled in 1969 but not previously published. (USGS)

Survey of selected organic compounds in aquifers of New York State excluding Long Island
Samples from 56 wells at 49 sites in New York State, excluding Long Island, were analyzed by gas chromatography/mass spectrometry for the presence of organic compounds designated ' priority pollutants ' by the U.S. Environmental Protection Agency. Most samples were taken from public-supply wells tapping shallow, permeable aquifers, the most susceptible to contamination. Analytical sensitivity reported by the laboratory for most compounds was less than 1 microgram per liter, but contamination during collection, shipping, or laboratory processing required that concentrations be about 10 micrograms per liter before the presence of a compound could be confirmed. Only a small percentage of wells sampled in this study was found to be contaminated. Where contamination is present, it probably results from point sources such as landfills or dumps rather than from general sources such as atmospheric deposition or proximity to urban centers. Two sites, Brewster in Putnam County and Olean in Cattaraugus County, showed clear evidence of contamination. Two other sites, Corning in Steuben County and Fulton in Oswego County, showed evidence of possible contamination. (USGS)

Ground-water appraisal of the Fishkill-Beacon area, Dutchess County, New York
The most productive aquifers in the Fishkill-Beacon area, Dutchess County, N.Y., are the sand and gravel beds in the northeast corner of the area and along the valleys of Fishkill and Clove Creeks. The average yield of these aquifers to wells is 190 gal/min (gallons per minute). The most productive bedrock aquifer is limestone, which yields an average of about 150 gal/min. Shale and granite each yield an average of less than 35 gal/min. About 4 billion gallons of available ground water is estimated to be in storage in the sand and gravel aquifers in the area. The area withdraws an average of 3.3 Mgal/d (million gallons per day) of water in June, July, and August and 2 Mgal/d during the remainder of the year.
