Entity and Attribute Overview | |
Entity and Attribute Detailed Citation | chempt | | | | RELATEID | Four 0's followed by 6 digit unique number for wells, or the Lake id from DNR Lakes Database + 2 digits for a site at a lake (01,02, etc.), or a 2-digit county number followed by 'A' followed by a 7-digit unique number for a spring | | AQUIFER | Aquifer code. The aquifers are identified as "QBAA", "CECR", "CEMS", "CTCE", "CWOC", "CTCW", "CWMS", "CJDN", "CMFL", "CMTS", "CSLT", "CSTL", "KRET", "MTPL", "OPCJ", "OPDC", "OSTP", "PMSU", "QWTA", and "CTLR". | | AQUIFER_Q | Quaternary aquifer name, usually mapped at county scale. The aquifers are identified as "sdo", "sg", "sr", "su", and "sx". Quaternary aquifers are named after surficial and buried sand units shown on Plate 4, Part A. Bedrock aquifers are represented by "bdrk ". | | TRITIUM | Tritium in Tritium Units (TU). | | TRIT_AGE | Residence time estimated from tritium value. "COLD WAR ERA" - Greater than 15 TU. "RECENT" - 8 to 15 TU.
"MIXED" - Greater than 1 TU and less than 8 TU.
"VINTAGE" - Less than or equal to 1 TU. | | ARSENIC | Arsenic concentration in micrograms per liter. | | CHLORIDE | Chloride concentration in milligrams per liter. | | | NITRATE_N | Nitrate concentration in milligrams per liter reported as Nitrogen | | | DATASOURCE | Source of data. | | C14_YEARS | Groundwater residence time in years, estimated by carbon-14 isotope analysis (Model estimated age in years rounded to 1 significant digit). |
