Title:
Compilation of Existing Hydrogeologic and Geospatial Data Useful for the Assessment of Focused Recharge to the Carbonate-Rock Aquifer in Genesee County, New York
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the New York State Department of Environmental Conservation (NYSDEC), compiled the digital data presented in this report. Existing hydrogeologic, and geospatial data were obtained from numerous local, state, and federal agency sources for this pilot study in central Genesee County, NY. The study focused on assessing the carbonate-rock aquifer through the compilation and interpretation of these data and presented as sets of maps to describe potential locations of surface water/groundwater interaction. Areas of potential surface water/groundwater interaction were identified from geospatial datasets, interviews with local highway departments and the Genesee County Soil and Water Conservation District, and an initial assessment of karst features through the analysis of orthographic photographs, and minimal field verification - not all karst features were identified in Genesee County because of limited time resources.

Why was the data set created?

Water-resource managers are encouraged to utilize the information summarized in this report as a guide to further assess areas where the connection between the land surface and ground water has been identified. In these areas, site visits should be made to determine the vulnerability of a particular site to surface water/groundwater interaction in relation to the resource activity or contamination source being assessed.

These data are intended for use at a scale of 1:24,000 or smaller. The primary intended use is for local and regional display and analysis. It is not intended for site-specific studies.

  2. How were the data generated, processed, and modified?

    Date: 2010 (process 1 of 6)
    Land surface elevation data in the form of Digital Elevation Models (DEM) were obtained from the USGS National Elevation Dataset (NED) for Genesee County, NY. DEM resolutions of 10 meter (1/3 arc-second) and 30 meter (1 arc-second) were acquired. These surface elevation datasets, coupled with depth to bedrock values acquired from various sources, were used to generate a bedrock surface dataset.

    Date: 2010 (process 2 of 6)
    Land cover data was obtained from the 2001 National Land Cover Data (NLCD) for Genesee County, NY. Resolution of the NLCD is 30 meters (1 arc-second). The NLCD was used to identify areas of agricultural land use within the carbonate-rock study area.

    Data sources used in this process:

    • NLCD

    Date: 2010 (process 3 of 6)
    Soils data was obtained from the U.S. Department of Agriculture (USDA), Soil Survey Geographic (SSURGO) Database for Genesee County, NY. The SSURGO data was used to identify soils that are shallow to bedrock and which have moderate to high infiltration rates.

    Data sources used in this process:

    • SSURGO

    Date: 2010 (process 4 of 6)
    Anthropogenic data (quarries, mines, and contamination sites) were obtained from the following sources.
    - NYS DEC Mining Database
    - Dr. Paul Richards, Dept. of Earth Sciences, SUNY at Brockport, NY
    - Genesee County Department of Health
    - SSURGO soils database
    
    The anthropogenic data from the various sources were combined and used to identify the locations of quarries/mines, sand and gravel pits, and known contamination sites.

    Data sources used in this process:

    • Anthropogenic

    Date: 2010 (process 5 of 6)
    Bedrock elevation data were obtained from the following sources.
    - NYS DEC Water Well Program
    - USGS Groundwater Site Inventory (GWSI) Database
    - NYS Department of Transportation
    - NYS Thruway Authority
    - SSURGO soils database
    
    The bedrock elevation data from the various sources were combined and used to generate a bedrock surface dataset.

    Data sources used in this process:

    • Bedrock elevation data sources

    Date: 2010 (process 6 of 6)
    Karst feature data were obtained from the following sources.
    - Dr. Paul Richards, Dept. of Earth Sciences, SUNY at Brockport, NY
    - Genesee County SWCD
    - Town of Batavia, NY; Highway Department
    - Town of Elba, NY; Highway Department
    - Town of Le Roy, NY; Highway Department
    - Town of Stafford, NY; Highway Department
    
    The karst feature data from the various sources were combined and used to generate an inventory of possible karst features within the carbonate-rock aquifer study area. The USGS StreamStats GIS application was used to delineate drainage basins for each of the karst features. In instances where the StreamStats derived basin for a karst feature was negligible, ArcGIS was used to assign the feature a 500-ft radius buffer zone in lieu of a drainage basin. ArcGIS Spatial Analyst extension was used to convert the drainage basins and buffer zones to a 10-meter resolution raster dataset.

    Data sources used in this process:

    • Karst features
