Annual Drinking Water Testing Program

An exciting opportunity to learn about the water you drink is being offered to all residents with private wells in Green County.  If you are interested in learning more about drinking water and the quality of your water, this program is an opportunity to have your well water tested at a reduced cost and learn of the results during an educational program with drinking water experts.  Groundwater specialists strongly encourage rural residents to test their water at least once every 2 years.

This program is neither mandatory nor regulatory.  It is completely voluntary.  Individual results will be kept confidential. Special bottles are required for these tests, and there is a cost for this testing.  You may choose one or more of the testing packages described below.

Options for Well Testing:

  • Homeowner Package (Includes tests for nitrate, coliform bacteria, pH, alkalinity, and hardness.) Cost =  $60.00
  • Metals Package (Tests for arsenic, lead, copper, iron, zinc, calcium, magnesium, manganese, sodium, potassium, and sulfate.)    Cost = $57.00
  • Triazine Screen (Includes tests for triazine type pesticides like atrazine)   Cost = $35.00

If you choose all three packages the cost is $146, a discount of $6.

Bottles will be available for pick-up at the following locations and times listed.  Bottles must be filled and returned on Monday, May 23, to the site where you picked up your bottles.  Tests must be paid for when the bottles are picked up.
