The Wyoming Department of Environmental Quality (DEQ) is encouraging private well owners to check their water wells regularly.  March 13th is "Know Your Well Day."

More than 75 percent of Wyoming’s population relies on groundwater for part or all of their drinking water supply. This water comes from more than 90,000 wells. Around a farm, ranch, or rural home-site, there are many potential contaminants that should concern the owner.

There is no government agency (federal, state, or local) that regulates water quality from private drinking water wells in Wyoming. This means that the water quality of these wells is not regularly checked unless the owner takes action to sample and test their water and protect and maintain their well.
