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", "CJDN", "CFIG", "CIGL", "CMTS", and "PMHN".

 

BD_AQ_NAME

Bedrock aquifer name. The bedrock aquifers are identified as "Jordan", "Upper Tunnel City-Wonewoc", "Wonewoc", "Mt. Simon", and "Hinckley".

 

AQUIFER_Q

Quaternary aquifer name, usually mapped at county scale. The aquifers are identified as "SDV", "SDJ", "SC", "SB", "SX", "SU", and "unnamed". Quaternary aquifers are named after buried sand units shown on Plate 5, Part A.  Bedrock aquifers are represented by " ".

 

TRITIUM

Tritium in Tritium Units (TU).

 

H3_NUM

Tritium in Tritium Units (TU) as a numeric value.

 

TRIT_AGE

Residence time estimated from tritium value.
"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.

 

AS_NUM

Arsenic concentration in micrograms per liter as numeric values (values equal to 0 mean not dectected or not sampled).

 

CHLORIDE

Chloride concentration in milligrams per liter.

 

CL_NUM

Chloride concentration in milligrams per liter as numeric values.

 

C14_YEARS

Groundwater residence time in years, estimated by carbon-14 isotope analysis (Model estimated age in years rounded to 1 significant digit).

  NEW_CODE Updated aquifer codes as of August 1, 2014 to account for stratigraphic nomenclature changes. The new codes correspond with the codes found under the AQUIFER field.
