- Abstract
- Aquifer_Sensitivity_Near_Surface_IN is a raster data layer that displays a reclassified raster data layer of estimated rates of diffuse groundwater recharge to the water table in shallow aquifers in Indiana (see Aquifer_Recharge_Near_Surface_IN). The goal of this project was to use an objective, reproducible methodology to rank aquifer sensitivity in shallow aquifers based on estimates of diffuse groundwater recharge rates. To achieve the aquifer sensitivity ranking, the groundwater recharge rates were classified by standard deviation, and the classifications were then compared to databases of contaminants in groundwater to validate the classification.
- Purpose
- This data set was created to support decision making in Indiana where knowledge of the sensitivity to aquifer contamination is desired.

- Data Quality Information
- Attribute Accuracy Report
- The ranges of all numeric attributes that went into the analysis were checked to ensure the values represented the content of the field. The attribute accuracy varies by the original source scale of the data used to calculate each field. Many high resolution data inputs used to calculate each field were degraded in scale when mean values or centroid samples were taken to represent the independent landscape variables at a resolution of 100 m.
- Logical Consistency Report
- Checks for duplicates (unique values in unique records) were performed on this data set. No checks on topology were performed on this data set.
- Completeness Report
- All fields were checked to ensure that all records were populated.
- Horizontal Positional Accuracy Report
- The raster resolution is 100 meters; the horizontal positional accuracy of the raster is 200 meters. The effective horizontal accuracy for the value attributes of groundwater recharge is unknown; the raster values represent a predicted value of groundwater recharge, but 95% confidence limits are not represented in this product.
