A large number of residences in Pitkin County receive water from private wells. The Colorado Division of Water Resources, through the state engineer, issues water well permits. Every new well in the state that diverts ground water must have a permit. Applications and instructions for obtaining a well permit are available online.
Well drillers and pump installers in Colorado are required to be licensed. Information on licensed contractors is made available by the state online. Unlike the inspection programs that exist for buildings, there is currently no inspection or certification program in place for well construction; however, the state has provided water well construction rules.
Unlike public water supplies, the responsibility for assuring a safe supply of water from private wells rests solely with the property owner. In Colorado, there are no regulatory standards governing the water quality of private wells and Pitkin County does not test its residents' well water. There are several private water laboratories in the state (PDF) which perform water testing.
