Summary The Environmental Protection Agency’s (EPA) Long Term Monitoring (LTM) network has supported the collection of stream chemistry data in the Catskills since the 1990s. Trends in stream chemistry have periodically been evaluated in these streams but the most recent assessments only extend through the early 2000s. An updated assessment of stream chemistry trends will help evaluate the effects of recent substantial declines in acid deposition during the last decade. This study will evaluate changes in surface water chemistry from 1991 through 2013 at 5 stations in the Neversink and Rondout watersheds in the Catskill Mountains of New York. The results will be compared to changes in atmospheric deposition...
Introduction As a result of storage and disposal practices at a former Manufactured Gas Plant, or MGP, in Bay Shore, NY, a variety of polycyclic aromatic hydrocarbons (PAHs) have been detected at high concentrations in the surficial, upper glacial aquifer of Long Island. Levels of PAHs initially detected over 10 years ago were in the parts-per-thousand range within a groundwater contaminant plume. The plume extended over a half-mile from MGP-related sources to discharge at a local estuarine tributary, Lawrence Creek, resulting, resulting in malodorous hydrocarbon sheens in this tributary and nearby storm drains. These signs of contamination revealed a larger underlying problem and prompted calls by state and local...

Problem - Acidic precipitation has affected forested and aquatic ecosystems in New York, particularly in the Adirondack and Catskill regions. Acidification of surface waters and deleterious effects on fish and other biota have been well documented in both these regions. Despite reduced levels of acidity in atmospheric deposition over the past 20 years across New York and the northeastern United States, the most acid-sensitive streams and lakes have not yet begun to recover, and many show continued declines in acid-neutralizing capacity, an indicator acid-base status. Many studies have documented the effects of acid precipitation in New York, but thus far, there has been no comprehensive effort to synthesize and...
Problem - The valley-fill deposits in Upper Buttermilk Creek/Danby Creek valleys are sources of water for many homeowners, farms, and small businesses that are in this valley. The aquifer was mapped by Miller (2000) and identified as one of the 17 aquifers in Tompkins County that needs to be studied in more detail. However, there is little geohydrologic data in the valley. A cluster of wells in Upper Buttermilk valley are finished in sand and gravel, indicating that there is a sand and gravel aquifer in, at least, part of the valley. The Upper Buttermilk Creek/Danby Creek valleys are "through valleys"-- a part of a valley where the bedrock floor rose to land surface and formed a preglacial surface-water divide....

Problem The quality of surface water has important effects on human and ecological health. Surface water is an important drinking water source and is used for swimming, fishing, and recreation, and the quality of surface water can have profound effects on the health, diversity, and resilience of ecological communities. The New York State Department of Environmental Conservation (NYSDEC) is tasked by the U.S. Environmental Protection Agency (USEPA) to monitor ambient water quality of the State. The NYSDEC is also tasked to develop Total Maximum Daily Loads (TMDLs) for state waters that fail to meet their intended use. A critical first step in maintaining high quality of surface-water is assessment of existing...

Problem The New York City Department of Environmental Protection (NYCDEP) has asked the U.S. Geological Survey (USGS) to assist in two major studies: 1) delineation of the source(s) of shallow groundwater and the extent that the Delaware Aqueduct is contributing to local flooding issues, and 2) delineation of the structural, geologic, and hydrologic conditions along proposed tunnel construction paths using advanced surface and borehole geophysical methods. The NYCDEP needs to determine the source of groundwater and surface water and their possible relation to leakage from the Delaware Aqueduct in upstate New York. The Delaware Aqueduct, which supplies a significant portion of New York City's water supply, has...
