Drinking Water Wells
|Test Your Water||Other Resources|
There are two state agencies that have regulations pertaining to construction specifications for water supply wells. The Wyoming State Engineer's Office provides well design requirements in the Regulations and Instructions, Part III, Water Well Minimum Construction Standards. The Department of Environmental Quality, Water Quality Division (WDEQ/WQD) does not regulate the construction of domestic (private) wells, but it is highly recommended that the well construction design complies with Chapter 26 and Chapter 12, Section 9 of Wyoming Water Quality Rules and Regulations to prevent groundwater contamination.

Well owners should be aware of the potential contaminants that could impact their drinking water. Groundwater can be contaminated by natural processes, by waste disposal practices, and by spills or leaks. A contaminated water supply is unsafe to use without treatment even though you may have used the same water for years without getting sick. Consuming polluted groundwater could cause illness, especially in infants, young children, pregnant women, the elderly, and people whose immune systems are compromised. The contaminants listed below are common in Wyoming and could cause long or short-term health problems.Methane

Test Your Water
DEQ recommends that you test your drinking water. As a private well owner, you are solely responsible for the quality of your drinking water. It is up to you to decide when and how to test your water. Testing is recommended when there is an unexplained illness in the household or there are changes in color, taste, or odor of the water. At a minimum, your water should be tested every year for bacteria, the most common water quality problem.See the Tests for Specific Conditions or Contaminants to help select what to test for and find a laboratory.
