Development of GIS datasets for selected aquifers in New York

Problem - Since the 1980s, the U.S. Geological Survey (USGS) has mapped over 30 sand and gravel aquifers in upstate New York at the 1:24,000-scale. These mapped aquifers include both the primary and many of the principal aquifers as designated by the New York State Department of Environmental Conservation. Although the 1:24,000-scale maps are valuable in their present form, their usefulness is...

The Effects of Watershed and Stream Liming on Mercury Dynamics at Honnedaga Lake

Problem The Adirondack region of New York has 128 lakes that are listed as impaired by acidity under section 303(d) of the Clean Water Act. Acidity can limit the survival and reproduction of native fishes such as brook trout (Salvelinus fontinalis). Chronic and episodic acidification also stresses fish, aquatic macroinvertebrates, and other biota of inflowing tributaries of these and many...

Estimating Acute and Chronic Toxicity of Waters from the Rochester Embayment Area of Concern Using Two Plankton Species

Background Discharges from non-point sources, municipal and industrial point sources, and combined sewage overflows over the last century resulted in elevated levels of heavy metals, conventional pollutants, phosphorus, and toxic organic contaminants in water and sediments of the Lower Genesee River and Rochester Embayment. As a result, the zooplankton and phytoplankton or “plankton”...

Groundwater Flow Patterns near Pulaski, Oswego County, New York

Problem - The Village of Pulaski in Oswego County, N.Y., obtains its water supply from groundwater that drains under gravity from an unconfined aquifer into three shallow dug wells. The well field is in an area where groundwater discharges to springs along the west edge of the Tug Hill Aquifer, which is comprised of beach and kame deposits of sand and gravel. A numerical groundwater model wa...

Ground-water-flow model of the Shenandoah Valley, Virginia and West Virginia

Problem - Increasing development within the Shenandoah Valley in recent years has placed additional demands on the region’s water resources. The sedimentary rocks in the Valley have been compressed and folded by tectonic forces to form a 5-km deep basin. Ground water, a principal component of the available water supply, flows through fractures in the sedimentary and crystalline rocks that un...

Anticoagulant rodenticide toxicity to non-target wildlife under controlled exposure conditions

Using these data, an adverse outcome pathway identifying molecular initiating and...

Anticoagulant rodenticides and wildlife: Concluding remarks

Rodents are known to affect human society globally in various adverse ways, resulting in a widespread demand for their continuous control.
