Name: DRASTIC Rating

Display Field: DRAS_CDE

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Polygon feature class representing the the relative susceptibility of Allen County to groundwater pollution. DRASTIC hydrogeologic settings incorporate the major hydrogeologic factors that control groundwater movement and occurence including depth to water, net recharge, aquifer media, soil media, topography, impact of the vadose zone media, and hydraulic conductivity of the aquifer. The relative ranking scheme uses a combination of weight and ratings to produce a numerical value called the pollution potential index that helps prioritize areas with respect to groundwater contamination vulnerability. This feature class also includes a special version of DRASTIC developed to be used where the application of pesticides is a concern. The weights assigned to the pesticide DRASTIC system were changed to reflect the processes that affect pesticide movement into the subsurface with particular emphasis on soils.
