GROUNDWATER USE    Water use figure

  • From 1979 to 2005, total water use in Jackson County has increased from about 2.5 million gallons per day to about 7.1 million gallons per day, though intervening years were variable.*
  • The increase in total water use is due to increases in irrigation. Domestic and industrial uses have decreased.
  • The proportion of county water use supplied by groundwater has been consistently above about 97% during the period 1979 to 2005.*
  • Water use in Wisconsin is generally estimated for the following categories:
    • Domestic
    • Livestock
    • Aquaculture
    • Irrigation
    • Industrial
    • Commercial
    • Public use and losses
    • Thermoelectric or mining*

* Thermoelectric and mining data are not considered in water-use tables or figures on this web site. Thermoelectric-power water use is the amount of water used in the process of generating thermoelectric power. The predominant use of water is as non-contact cooling water to condense the steam created to turn the turbines and generate electricity.



  • Wisconsin has abundant quantities of high-quality groundwater, but once groundwater is contaminated, it's very expensive and often not technically possible to clean.
  • An evaluation of the susceptibility of groundwater to contamination in Jackson County can be seen in the FULL REPORT or accessed through the map link above.


  • 84% of 299 private well samples collected in Jackson County from 1990-2006 met the health-based drinking water limit for nitrate-nitrogen.   Nitrate map
