Short description:
Aquifer Sensitivity (Near surface) – Shows ranked categories of aquifer sensitivity in shallow aquifers in Indiana, and is based on estimates of diffuse groundwater recharge rates. The hypothesis is that near-surface contaminants are more likely to migrate downward in areas of increased groundwater recharge. To achieve the aquifer sensitivity ranking, the groundwater recharge rates (see Aquifer_Recharge_Near_Surface_IN.TIF) were classified by standard deviation, and the classifications were then compared to databases of contaminants in groundwater to validate the classification. These data (along with the associated data layer named Aquifer_Recharge_Near_Surface_IN.TIF) were created to support decision making in Indiana where knowledge of groundwater recharge rates and sensitivity to aquifer contamination is desired.
