Well Water

A large majority of homes in Grand County are served by a drinking water private well. Private wells health and safety is the responsibility of the homeowner. EPA and CDPHE recommend testing your drinking well at least annually for coliform bacteria and nitrates. More information on private wells drinking water and your health can be found at CDPHE Drinking Water Private Wells. 


Colorado Department of Public Health and Environment (CDPHE) manages well water testing.  Follow the steps below.

1. Go to CDPHE's Homeowner Water Testing page.

2. Complete their water testing bottle form.  Supplies are free of charge and arrive via FedEx. Alternatively, you can pick up sample bottles for coliform in the County Community Development Department located at the lower level, west end, of the County administration building in Hot Sulphur Springs.

3. Choose Water Testing Package. If you've never had your well tested before, we recommend the "General Colorado Package" which tests for the eight most common problems associated with Colorado groundwater. The "Deluxe Package" is more expensive but provides more information.

4. Payment for water testing is due at the time of water sample submission via drop off or mail.
