Detailed Aquifer Mapping in Wayne County, New York
Detailed mapping of the glacial aquifer within the buried Fairport-Lyons bedrock channel in southern Wayne County, New York is the latest study in the cooperative Detailed Aquifer Mapping Program between the USGS New York Water Science Center and the New York State Department of Environmental Conservation (NYSDEC). The aim of the program is to map the extent of glacial aquifers in New York State at a scale of 1:24,000.
This information is used by NYSDEC Division of Water and others for delineation of groundwater contributing areas, assessing potential threats to aquifers from both point and non-point sources, responding to contamination from spills or leaks from underground storage facilities, and providing information to assess the need to permit new or expanded public water supplies.
The objective of the study is to investigate the hydrogeology of the Fairport-Lyons channel and inter-drumlin outwash channels. The hydrogeologic setting of the Fairport-Lyons channel aquifer system is different from those previously studied in New York because sand and gravel deposits within drumlin fields are very uncommon, and few hydrogeologic investigations have been completed in this type of geologic setting. Lidar-derived DEMs and hillshades are a critical tool for delineating the spatial extent and hydrogeologic framework of this valley-fill aquifer system.
