Water resources is a composite of two data sets:

- highly transmissive aquifers, based on USGS detailed aquifer
  studies
- wellhead protection areas, based on DES WHPA data

Attributes in the data set include:

HIGHYLD - 0:  not an aquifer
          1:  tranismisivity 2000+ ft/sq/day
          2:  transmissivity <2000 ft/sq/day

WHPA    - 0:  not a wellhead protection area
          1:  wellhead protection area
