This data set is a\nresult of a larger work (WRIR 00-4103 cited above), which\nincludes a paper plate titled: \"Map showing sensitivity of\nground-water to contamination in Lawrence County, South Dakota.\"\nThis data set is part of the digital data that was used to create\nthat map.  The sensitivity-unit code is an attribute that\nconsists of a letter followed by three numerical digits,\nwhich characterizes sensitivity to contamination.  Letter codes\nthat begin with upper case letters (A-Z) and continue with lower case\nletters (a-s) represent characteristics of the rock and sediments,\nwith 'A' being most sensitive and 's' being least sensitive. The first\ndigit represents recharge rate with 1 being the most sensitive and 4\nthe least sensitive. Three quantitative categories (1-3) and\ntwo qualitative categories (4,5) represent depth to water.\nGroups 1 through 3 represent areas where data was available\nto estimate depth-to-water with 1 most sensitive and 3 least\nsensitive. Qualitative categories 4 and 5 represent areas that only\ncan be compared to each other with 4 being the most sensitive.\nThe third digit represents land-surface slope with 1 being\nthe most sensitive and 5 being the least sensitive.  An additional\nattribute, hydrologic setting, represents areas with common hydrologic\ncharacteristics.  These 11 hydrologic settings are represented by a\nletter code symbol.  The process step section below describes the\nattributes in more detail and how the attributes were developed from\nsource data. The source data includes digital maps that characterize\nthe geology, precipitation distribution, and water levels, which have\nbeen compiled at 1:100,000 scale and published in 1999 and 2000\nas part of the Black Hills Hydrology Study. USGS Digital elevation\nmodels were used to describe land-surface altitudes.
