U.S. Geological Survey http://water.usgs.gov/lookup/getspatial?regolith This dataset is a representation of the depth in feet to bedrock as reported in the driller's log for the Water Wells Database of the Tennessee Department of Environment and Conservation (TDEC), Division of Water Supply (DWS). The coverage "Superfund GIS - Private Well Locations for Tennessee" was used to provide locations while a field retrieval from the DWS database was used to provide depths in feet. To get an approximation of the depth in feet to bedrock at any given location in the state of Tennessee. Procedures_Used: The Private Well Locations coverage was merged with the depth in feet to bedrock field from the DWS database. Records which had a 0 or a missing value in the DTBI field were deleted. The remaining points were left in the coverage as is.
