Problem - The major hydrogeologic units of Long Island, New York, have been delineated as part of the islandwide mapping effort of Smolensky, Buxton, and Shernoff that was published in 1989 as U.S. Geological Survey (USGS) Hydrologic Atlas (HA) 709. Concern about local details in the hydrogeologic framework that may not be represented in HA-709 has led the USGS, in cooperation with the U.S. Environmental Protection Agency (EPA), to assess the hydrogeology of the Long Island area so ground-water-flow modeling planned by EPA can more fully reflect local hydrogeologic conditions. Objectives - The primary objective of this project is to construct geographic information system (GIS) datasets of the altitudes of the...

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 : 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...

Background Past water-quality issues in the St. Lawrence River at Massena, NY resulted in a determination that selected beneficial uses may be impaired in a surrounding Area of Concern (AOC) and on the Canadian side of the international boundary (Cornwall, Ontario). The plankton (phytoplankton zooplankton) Beneficial Use Impairment (BUI) was so designated because impairment metrics were unavailable or inconclusive. Recent investigations, however, suggest that plankton communities are relatively healthy and no longer threaten the local ecosystem. Thus, the BUI for plankton may now be outdated in all, or parts of, the St. Lawrence River in the Massena AOC. The primary goal for the Massena (and Cornwall) Remedial Action...

Background: The USGS propose a collaborative investigation with the NYSDEC and NOAA to evaluate the current condition of benthic macroinvertebrate communities and toxicity of bed sediments in the Niagara River Area of Concern (AOC). Using a probabilistic study design, sediment-toxicity data compiled by the USGS, invertebrate community data collected by NYSDEC, and sediment-chemistry data collected by NOAA will be assimilated using a Sediment Quality Triad approach (Chapman et al., 1992; USEPA, 1992) to provide a sediment-quality baseline needed to gauge changes expected to follow remediation of contaminated sediments in parts of the AOC. These data will also be used directly to confirm that the macroinvertebrate...

Problem - There is a stated need to provide information on loading of persistent toxic pollutants to Lake Ontario from New York tributaries. The information is specifically required for the Lake Ontario Mass Balance Model, which is an integral part of the long-term Great Lakes research. The project described here is designed to demonstrate a cost-effective approach for estimation of loads of polychlorinated-biphenyls (PCBs) through use of a relatively small number of large-volume whole-water samples for PCB analysis. The Black River basin was selected to demonstrate the feasibility of the approach because it is the largest New York contributor of PCBs to Lake Ontario. Objectives - The objective of this project...

The National Network of Reference Watersheds is a collaborative and multipurpose network of minimally disturbed watersheds and monitoring sites. The purpose of this website is to allow users to search the NNRW database of reference watersheds, to identify watersheds of interest, and download watershed information and water quality data. The current scope of the network is limited to freshwater streams. Membership in the network is voluntary and open to individuals, agencies, and institutions interested in participating in monitoring and (or) research in minimally disturbed and pristine watersheds. The NNRW defines reference watersheds as those minimally disturbed by human activity preferably in an area protected...

Background: The USGS propose a collaborative investigation with the NYSDEC to evaluate the current condition of benthic macroinvertebrate communities and toxicity of bed sediments in the Eighteenmile Creek Area of Concern (AOC). Sediment-toxicity data provided by the USGS and benthic-community data provided by the NYSDEC from inside the AOC will be compared to similar data from non-AOC sites in Eighteenmile Creek or nearby reference streams (of comparable drainage areas) to determine if the benthos-BUI (Beneficial-Use Impairment) designation is appropriate or if the BUI could be removed in Eighteenmile Creek. The remainder of this pre-proposal addresses only the direct USGS (sediment toxicity assessment) contribution...

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,...
