Episodic acidification of small streams in the northeastern United States: Ionic controls of episodes Episodic acidification of small streams in the northeastern United States: Ionic controls of episodes

As part of the Episodic Response Project (ERP), we intensively monitored discharge and stream chemistry of 13 streams located in the Northern Appalachian region of Pennsylvania and in the Catskill and Adirondack Mountains of New York from fall 1988 to spring 1990. The ERP clearly documented the occurrence of acidic episodes with minimum episodic pH ≤ 5 and inorganic monomeric Al (Alim)

Episodic acidification of small streams in the northeastern United states: Effects on fish populations Episodic acidification of small streams in the northeastern United states: Effects on fish populations

As part of the Episodic Response Project (ERP), we studied the effects of episodic acidification on fish in 13 small streams in the northeastern United States: four streams in the Adirondack region of New York, four streams in the Catskills, New York, and five streams in the northern Appalachian Plateau, Pennsylvania. In situ bioassays with brook trout (Salvelinus fontinalis) and a...

Mean annual runoff, precipitation, and evapotranspiration in the glaciated northeastern United States, 1951-80 Mean annual runoff, precipitation, and evapotranspiration in the glaciated northeastern United States, 1951-80

Two maps, compiled at 1:1 million scale, depict mean annual runoff, precipitation, and evapotranspiration in the part of the United States east of Cleveland, Ohio and north of the southern limit of glaciation. The maps are mutually consistent in that runoff equals precipitation minus evapotranspiration everywhere. The runoff map is based on records of streamflow from 503 watersheds in...

Analytical methods of the U.S. Geological Survey's New York District Water-Analysis Laboratory Analytical methods of the U.S. Geological Survey's New York District Water-Analysis Laboratory

The New York District of the U.S. Geological Survey (USGS) in Troy, N.Y., operates a water-analysis laboratory for USGS watershed-research projects in the Northeast that require analyses of precipitation and of dilute surface water and soil water for major ions; it also provides analyses of certain chemical constituents in soils and soil gas samples. This report presents the methods for...

Effects of surficial geology, lakes and swamps, and annual water availability on low flows of streams in central New England, and their use in low-flow estimation Effects of surficial geology, lakes and swamps, and annual water availability on low flows of streams in central New England, and their use in low-flow estimation

Equations developed by multiple-regression analysis of data from 49 drainage basins in Massachusetts, New Hampshire, Rhode Island, Vermont, and southwestern Maine indicate that low flow of streams in this region is largely a function of the amount of water available to the basin and the extent of surficial sand and gravel relative to the extent of till and fine-grained stratified drift...

Application of electromagnetic logging to contamination investigations in glacial sand-and-gravel aquifers Application of electromagnetic logging to contamination investigations in glacial sand-and-gravel aquifers

Electromagnetic (EM) logging provides an efficient method for high‐resolution, vertical delineation of electrically conductive contamination in glacial sand‐and‐gravel aquifers. LM. gamma, and lithologic logs and specific conductance data from sand‐and‐gravel aquifers at five sites in the northeastern United States were analyzed to define the relation of KM conductivity to aquifer...

Preliminary delineation of contaminated water-bearing fractures intersected by open-hole bedrock wells Preliminary delineation of contaminated water-bearing fractures intersected by open-hole bedrock wells

Contaminated water‐bearing fractures intersected by open‐hole bedrock wells were preliminarily delineated through a combination of geophysical logging, vertical‐flow measurements, and downhole water sampling as part of remedial site investigations in southeastern New York. The wells investigated range from 100 to 450 feet in depth, have only shallow surface casing, and intersect multiple...

Geochemical comparison of ground water in areas of New England, New York, and Pennsylvania Geochemical comparison of ground water in areas of New England, New York, and Pennsylvania

In New England, the ground-water geochemistry results mainly from the reaction of CO2-charged water with feldspar and other primary silicates. Water in the New England bedrock is more highly evolved geochemically than water in the drift, presumably as a result of its longer residence time. In the New York area, the geochemistry of water in both types of aquifers results mainly from...
