Water Sampling

"...working to enhance our community's total well-being by promoting healthy lifestyles, protecting health, and preventing disease."

Effective December 1, 2018, the Calhoun County Public Health Department, revised the drinking water sampling process due to contracted drinking water laboratory services revisions:
  • The Environmental Health Department will only accept Coliform and Nitrate water samples. The samples must be in our office by 12:00 pm (noon) on Monday, Tuesday, and Wednesday. If the sample was taken in the morning, bring in by noon or take water sample late afternoon and bring in by 3:00 pm.
  •  Water samples must be brought in by noon on Thursday.
  • No water samples are accepted on Friday.
  • If you need to test your water for something other than Coliform and Nitrates, please contact the Department of Environmental Quality (DEQ) water laboratory at 517-335-8184 who will ship the bottles to you.

Two water testing options are:

  • Health Department Visit
    Call Environmental Health to make an appointment with a sanitarian to sample your water supply. Sanitarians are available at the time of the visit to answer any water well questions and concerns and determine if additional tests are needed. The basic test includes coliform bacteria and nitrates.
  • Do-it-Yourself Kits
    Environmental Health offers pre-addressed water bottle kits. You can test for coliform bacteria and water chemistries: nitrate, nitrite, chloride, fluoride, hardness, iron, sodium, and sulfate.
Do-it-Yourself kits can be picked up at the Environmental Health office at 190 E. Michigan Avenue, Battle Creek, MI. Directions are provided with the kit, including the mailing address. Mail to the address provided in the kit along with a check or money order for lab fees.
Sample your water supply in the afternoon and ship immediately. Environmental Health suggests checking your post office outgoing mail schedule prior to sampling. Samples are sensitive – if the sample was taken over 30 hours from time of testing, the lab considers the sample invalid.
If you have any questions about this process or need further information, contact Environmental Health at 269-969-6341.
