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.

Data sources used in this process:
- NYS DEC Mining Database - Dr. Paul Richards, Dept. of Earth Sciences, SUNY at Brockport, NY - Genesee County Department of Health - SSURGO soils databaseThe 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:
- NYS DEC Water Well Program - USGS Groundwater Site Inventory (GWSI) Database - NYS Department of Transportation - NYS Thruway Authority - SSURGO soils databaseThe bedrock elevation data from the various sources were combined and used to generate a bedrock surface dataset.
Data sources used in this process:
- 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 DepartmentThe 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:
Version 1.0 - subsequent versions may contain more data and/or a greater diversity of data types.
Polygon and chain-node topology present
