Water Testing Kit

Those that wish to test their own water can pick up water testing kits and forms (with instruction) and the Dubuque County Health Department from 8 am – 4:30 pm. Samples may be submitted Monday – Thursday from 8 am - 4:15 pm.

You do not need to be a Dubuque County resident to have your water tested at the Dubuque County Health Department.

If you are interested in receiving a free water test for your private well, the Dubuque County Health Department is able to do so through the FY22 Grants to Counties program. Call us today at 563-557-7396 to make an appointment.
