Licensed Well Drillers

Private well construction has been regulated in the state since 1985 when the Missouri Water Well Drillers Act (Sections 256.600 to 256.640 RSMo) became law establishing well construction standards aimed at protecting Missouri’s groundwater. Missouri requires private well water sampling for households only during well installation. The quality of water produced by private wells is not monitored or regulated.
