This layer was developed specifically to serve as a parameter in a
ground-water vulnerability to surface contamination study conducted at
the Wyoming Water Resources Center. The DRASTIC-based model requires
vadose zone rating as one of its parameters. No other suitable
uses for this data are known.
This dataset represents an aquifer sensitivity rating for the vadose
or unsaturated zone in the State of Wyoming. This dataset is specifically
to be used within a DRASTIC-type aquifer sensitivity/vulnerability
analysis.
