Background A major focus of the NAWQA Program in its second decade (2002-2013) is on regional- and national-scale assessments of groundwater-quality status and trends in principal aquifers. The U.S. Geological Survey Office of Groundwater has identified 62 principal aquifers in the U.S. ( U.S. Geological Survey, 2003 ). About 1/3 of the Nation's principal aquifers are the focus of water-quality assessments at the regional scale by NAWQA. The NAWQA framework for principal aquifer assessments considers the physical setting of the aquifer, in addition to its susceptibility and vulnerability to contamination.

The current information available for the Genesee River and watershed is insufficient to assess if the Beneficial Use Impairment (BUI) delisting criteria for the Rochester Embayment Area of Concern (AOC) can or have been met. With on-going and future projects that are implementing best practices to control soil erosion and the reduction of nutrients that reach the Rochester Embayment, the river and the watershed, it becomes a necessity to: 1.) collect more frequent Total Suspended Sediment (TSS) data for the Genesee River both within and outside of the AOC; and 2.) to have a study design capable of evaluating the impact/success of the current and proposed GLRI projects in the watershed. This project is envisioned...

BACKGROUND Chemistry data from a group of Adirondack lakes monitored since the mid-1990s indicate that chemical recovery is currently underway and can be attributed to declining deposition loads of sulfate and nitrate in direct response to the 1990 amendment to the Clean Air Act (CAA) and other regulations. Changes in the water quality of several western Adirondack streams suggest that chemical recovery from acidification is underway as well, while data from recent large-scale stream surveys also support the assertion. Changes in stream chemistry, however, appear to be more complicated than changes in lake chemistry. The pH levels in Buck Creek, for example, have changed very little since the 1990s but dissolved...

Introduction The upper Esopus Creek watershed is located in the eastern Catskill Mountains of New York State and covers 497 km2 from Slide Mountain, the highest peak in the Catskills at 1,274 m, to the Ashokan Reservoir at 193 m elevation (fig. 1). Suspended sediment and turbidity are primary water quality concerns in the Ashokan Reservoir watershed, part of the New York City Catskill-Delaware water supply system that supplies more than 10 million people a day with clean drinking water. Stream corridor assessments of tributaries to the Upper Esopus Creek by Ulster County Soil and Water Conservation District, New York City Department of Environmental Protection, and State University of New York at New Paltz summer...

More than 90% of the Pacific population of Steller’s eider (Polysticta stelleri) spends a portion of the fall in Alaska during fall wing molt and staging period, mostly along the Alaska Peninsula. The long-term Steller’s eiders counts from fall emperor goose surveys have shown declines at Izembek Lagoon and Port Heiden and approximate stability at Seal Islands and Nelson Lagoon (1992-2015, USFWS unpubl. data). Spring surveys for Steller’s eiders have been conducted along the north side of the Alaska Peninsula by USFWS since 1992; fall oblique photographic surveys covering the same area began in 2012.Systematic transect-based “overhead” photography is a method proposed for the fall survey and will be used to generate...

From 1995 to 1999, a subset of nest plots were searched twice by field crews to estimate nest detection probability by mark-recapture methods. Over the five years, 30 plots were searched twice and over 2700 unique nests were found. From these data, nest detection probability is estimated using a Huggins-type mark recapture model where individual-level covariate effects of nest and observer attributes were estimated. These estimates are then used to predict nest detection rates in other years based on covariates of nests and observers. Nest detection rates are then applied to annual plot search to estimate nest populations for each species in the sampled area.

The primary objective of this project was to monitor the growth of shorebird chicks by recapturing them from hatch to fledgling in relation to food abundance and weather conditions. In 2014 and 2015, we attempted to estimate the impacts of trophic mismatch by experimentally creating late hatched broods by refrigerating eggs to delay hatch. Transmitters were then attached to adults and chicks to follow and recapture chick in order to estimate growth rates and survival (see annual protocol documents for further information).Information for the Utqiagvik chick monitoring study were obtained concurrently with information obtained for the Utqiagvik shorebird project and information on chicks and nests included in these...
The Bluestone sculpin (Cottus sp.) is a priority at-risk freshwater fish endemic to the Bluestone River system in Virginia and West Virginia. The species occurs in small, cool streams with gravel and rubble dominated substrates. The taxonomic status of the Bluestone sculpin is unresolved, and its range often overlaps with congeners, with which it may hybridize. To address the conservation status of the Bluestone sculpin, taxonomic analyses are needed to fully describe the species and evaluate the level of hybridization. Additionally, comprehensive surveys and genetic analyses are needed to determine the species range and population connectivity. Locating the species using eDNA may be a viable option.

Information about the amount of habitat needed to support monarchs and how it should be distributed across the landscape will have direct implications for FWS habitat restoration programs. In the St. Croix Wetland Management District (WMD), this information will inform decision making for prioritizing Partners for Fish and Wildlife Projects on private lands as well as upland restoration efforts on WPAs and partner lands. The monarch information gained from this project will be another piece of the ecological puzzle, in addition to waterfowl, endangered species and grassland bird information for landscape-level restoration projects. In addition, the St. Croix WMD is partnering with the National Park Service, U.S....

The Virginia Department of Transportation (VDOT) Geologic Sections dataset consists of site-specific, large-scale geologic cross-sections (composite sheets). These sections were acquired from VDOT in order to save them from disposal. There are 5,500 geological profiles created for highway construction projects containing extensive core, auger and split-spoon logs at scales of 1:50 and 1:100 providing a unique record of subsurface geological and geotechnical data along roadways throughout Virginia. The thousands of feet of vertical subsurface data represents millions of dollars of investment in data acquisition by VDOT. The sections are useful as indicators of subsurface geology in large parts of Virginia. ...

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...

Problem - The Ithaca Subdistrict Office of the U.S. Geological Survey (USGS) is providing technical assistance to the USGS, Biological Resources Division (BRD), at the Tunison Laboratory of Aquatic Science (TLAS) in an investigation of the availability of fresh ground water. An expansion in the water supply at the laboratory is needed for a proposed spawning facility for salmon strains that are viable for natural fisheries in the Great Lakes region. The hydrogeology of the area is a complex of moraine and outwash deposits west of Cortland, N.Y. Data from existing wells at the laboratory indicate that well screens may readily clog from precipitated minerals. A review of the hydrogeology of the area, including...

Problem - The New York City Department of Environmental Protection (NYCDEP) is constructing or proposing water tunnels under New York City and areas of southeastern New York (Hudson River Basin). These tunnels can intersect faults and fractures that produce large amounts of ground water. For example, one tunnel excavation intersected fractures that produced over 200 gallons per minute of ground-water flow into the tunnel. Consequently, there is a need to determine the potential of intersecting ground-water producing fractures during tunnel excavation. The use of advanced borehole geophysical techniques by the USGS during tunnel excavations in northern Queens County demonstrated that geophysical techniques can...

The combination of a complex hydrogeologic framework, narrow land masses surrounded by saltwater, and extensive ground-water public-supply pumpage has produced localized areas of elevated chloride concentrations in ground water. This project uses advanced surface and borehole geophysical methods to determine the extent of saltwater intrusion and road-salt plumes at selected sites in eastern Suffolk County, Long Island, NY. Two-dimensional resistivity sections have been integrated with borehole geophysical logs and water-quality data to produce cross-sections of road-salt plumes. Borehole geophysical logs are collected twice a year to determine variations in chloride concentration and thicknesses of intrusive...

Background Past water-quality issues in the St. Lawrence River at Massena, NY resulted in a determination that selected beneficial uses were impaired in a surrounding Area of Concern (AOC) and on the Canadian side of the international boundary (Cornwall, Ontario). The benthic macroinvertebrate community or “benthos” Beneficial Use Impairment (BUI) was designated degraded because impairment metrics were unavailable or inconclusive. Recent sampling efforts by New York State Department of Environmental Conservation (NYSDEC) as part of their Rotating Integrated Basin Studies (RIBS) program indicate that macroinvertebrate communities in some sections of the St. Lawrence River and its tributaries in the Massena AOC are...

Background : Contaminated bed sediments in much of the Buffalo River AOC (Figure 1A, 1B) were removed (dredged) between 2011 and 2015. Plans to monitor and assess the effectiveness of this management action on 8 of 9 beneficial-use-impairments (BUI), included the benthic macroinvertebrate (benthos) BUI, were revised by the Buffalo Niagara Riverkeeper (Riverkeeper, 2014). Funds needed to implement various monitoring efforts proposed in this plan, however, were not available at that time. The USGS-New York Water Science Center (NYWSC) and the NYSDEC propose a collaborative study to evaluate multiple lines of evidence (toxicity of sediments and the condition of benthic macroinvertebrate communities) to determine...
