Summary Acid rain levels in the Adirondack region have substantially declined and recovery from acid rain is underway. Recovery is being limited by the depletion of soil calcium that occurred over past decades. Not only is calcium needed for neutralizing acidity, it is an essential nutrient for terrestrial and aquatic ecosystems. However, recovery of soil calcium has not yet been observed. Whole-ecosystem restoration through watershed liming, possibly combined with in-stream liming, may provide a practical option for stimulating recovery of certain acid-sensitive, high-value natural resources. Information from past liming efforts, however, is insufficient for determining the degree of success that could be achieved...
Problem - The U.S. Geological Survey (USGS) provided technical assistance between 2001 and 2013 to the U.S. Environmental Protection Agency (EPA) in an investigation of the presence of chlorinated solvents (trichloroethylene and degradates) in ground water in the Middle-to-Lower Devonian and Upper Silurian carbonate bedrock southwest of Auburn in Cayuga County, N.Y. Pieziometric and water-quality data from the wells indicate that contaminants may have migrated in the bedrock as far as 7 miles toward discharge areas that are in an adjacent surface-water basin. The ground-water contamination site was added to the Super Fund priority list in 2003. Objectives - The objective of the work is to characterize the stratigraphy,...

BACKGROUND Air emissions from the combustion of fossil fuels in electrical power plants, building heating systems and vehicles are the major source of gaseous sulfur (SOx) and nitrogen (NOx) oxides in the atmosphere. These oxides dissolve in atmospheric moisture forming ions which are deposited by rain, snowfall and dust particles as acidic deposition. Acidic deposition releases soluble aluminum from the soil which can reach toxic concentrations in adjacent water bodies such as streams and wetlands. Acidic deposition also removes important nutrients such as calcium, potassium and magnesium from the soil negatively impacting local flora and fauna. Depletion of calcium combined with excess aluminum makes forest...
Background: The New York State Departments of Environmental Conservation (NYS DEC) and Health (NYS DOH) are concerned about groundwater contamination in the carbonate-bedrock aquifers in New York, especially relating to the unintended introduction of volatile organic compounds (VOCs) and liquid manure to these aquifers. These carbonate rocks form extensive aquifers that transmit, and can yield, water from solution-enlarged fractures, bedding planes, and other openings (Olcott, 1995). Groundwater contamination from liquid manure application (fecal coliform bacteria [E. coli] and nitrate) has been on the increase over the past decade as these incidents have been reported to the NYS DEC. Nitrate is highly water-soluble...
Problem Water temperature is a critical component of trout habitat. Stream temperatures not only affect the distribution, behavior, and survival of trout (and other species), but also compel these species to move toward small areas of preferred temperatures, known as refuges, to maximize growth, survival, and fitness. The Schoharie watershed in the Catskill Mountains, including East Kill, West Kill, and Batavia Kill tributaries as well as the main-stem Schoharie Creek, supports small or transient populations of wild brook trout as well as naturalized and hatchery brown trout. Water temperatures in parts of these rivers typically exceed lethal thresholds for these species for several weeks each summer. Managing agencies...

BackgroundDetailed investigations of mercury cycling and bioaccumulation have been done in the Upper Hudson River basin (upstream of the Hudson River near Newcomb, in New York's Adirondack Mountains, with a focus on the Fishing Brook sub-basin, part of the western headwaters of the Hudson River. This study is part of a National mercury study that includes a concurrent study of McTier Creek, a headwater sub-basin of the Edisto River, located in South Carolina's Coastal Plain. These two study areas provide contrasting and complementary settings for the study of mercury cycling and bioaccumulation in headwater streams with close connectivity to out-of-channel wetlands. Atmospheric deposition is the dominant source...

Problem The Peconic Estuary of eastern Long Island, New York, is undergoing development as the region transitions from a rural area dependent on agriculture and tourism to a suburban one with a larger year-round population. The glacial and coastal-plain sediments underlying Long Island comprise a sole-source aquifer system that supplies the region’s communities with potable water. The area surrounding the Peconic Estuary was intensely farmed prior to suburbanization. Nitrogen loading from past fertilizer use was high as estimated from historical information and the continued detection of legacy effects in the aquifer system. In some areas, the peak or bolus of agricultural nitrogen loading from practices several...

Problem: The Great Lakes Restoration Initiative (GLRI) was established to accelerate ecosystem restoration in the Great Lakes by confronting the most serious treats to the region, such as nonpoint source pollution, toxic sediments, and invasive species. Much of the effort associated with GLRI is being placed near the most impacted areas in the Great Lakes Basin. Priority Watersheds have been targeted by the Regional Working Group’s Phosphorus Reduction Work Group. These Priority Watersheds (Fox/Green Bay, Saginaw, Genessee, and Maumee) are characterized by having a high density of agricultural land use and have ecosystem impairments that have been clearly identified. The outlet of each of the Priority Watersheds...
Background and Problem The Retsof salt mine in the Genesee River valley, Livingston County, New York flooded after roof collapses in 1994 created two rubble chimneys in overlying bedrock that intersected a confined aquifer in the basal glacial-drift deposits (figs. 1 and 2). Groundwater flowed downward through the rubble chimneys causing widespread drawdown in the lower confined aquifer until the mine was completely flooded in 1996 (Yager and others, 2001). By 2005, water levels in the lower confined aquifer had nearly recovered to pre-collapse conditions but the hydraulic connection through the rubble chimneys between the brine-filled mine cavity, saline-water bedrock fracture zones, and the lower confined aquifer...

Following Hurricane Sandy, the USGS began construction of an overland Surge, Wave, and Tide Hydrodynamics (SWaTH) Network along the Northeastern Atlantic Coast from North Carolina to Maine. This network, developed collaboratively with numerous partners, features the integration of long-term tide gage networks, with real-time rapid-deployment gages (RDG) and mobile storm-tide sensors (STS). An element of the comprehensive strategy of SWaTH ensures that locations for most RDGs and STSs have been presurveyed to the North American Vertical Datum of 1988 (NAVD 88) and equipped with receiving brackets. This permits rapid deployment and recovery of instrumentation and data dissemination in the hours and days immediately...

PROBLEM Alley Creek, a tributary to Little Neck Bay (Queens County, New York; figure 1) has been designated as impaired by the New York State Department of Environmental Conservation (NYS DEC) for primary and secondary contact and included on the 303(d) Impaired Waterways for pathogens related to combined sewer overflow contributions. The New York City Department of Environmental Protection (NYC DEP) and New York City Parks & Recreation have developed a long-term control plan (2014) and a watershed management plan (2015), respectively, to improve water quality and ecosystem health. Point and non-point sources of pathogens are implicated, including stormwater and combined-sewer outfalls, groundwater seepage, and...

Background: The New York City Department of Environmental Protection (DEP) maintains an extensive network of reservoirs and aqueducts for water collection, storage, and transport; it supplies more than one billion gallons of drinking water daily to more than nine million people. The East of Hudson (EOH) network (fig. 1) includes thirteen reservoirs – Amawalk, Bog Brook, Boyd Corners, Cross River, Croton Falls, Diverting, East Branch, Kensico, Middle Branch, Muscoot, New Croton, Titicus, and West Branch – and three regulated lakes – Kirk Lake, Lake Gilead, and Lake Gleneida. The EOH reservoirs were put into service from 1873 to 1915 and have an estimated combined storage capacity of more than 117 billion gallons....
