Kentucky statute and regulations now require water well drillers to be certified. Farmstead wells and stock wells are exempt except when a farmstead well is used for irrigation or domestic water supply. Since animal consumption wells are covered there is some confusion regarding stock wells. The Kentucky Division of Water strongly recommends that all wells, regardless of use, be drilled and constructed by a certified driller.
