Water Well Drilling Contractors in Arkansas

Geology & Depth

Eastern Arkansas sits atop the Mississippi Alluvial Plain with thick deposits of sand, gravel, and clay that yield productive shallow wells. The Ozark Plateau in the northwest has karst limestone and dolomite terrain with more variable groundwater access.

Most residential wells in Arkansas are drilled to 165 feet, with a typical range of 50–500 feet. Water table depth: 20-80 feet in the Delta region; 100-500 feet in the Ozarks and Ouachita Mountains.

Permits & Licensing

Arkansas requires water well drillers to be licensed through the Arkansas Department of Health. Homeowners may drill their own wells on their property but must meet construction standards.

Permit authority: Arkansas Natural Resources Commission (ANRC); registration required for all non-domestic wells. Expect $25-$100 in permit fees.

Primary Aquifer

Mississippi River Valley Alluvial Aquifer / Ozark Aquifer. About 20% of Arkansas residents depend on private wells, especially in the Ozark and Ouachita mountain regions.

Best drilling months: March through November; spring flooding in the Delta can delay access to drill sites.

Common Water Quality Concerns

Arkansas well water commonly contains: iron, manganese, hardness, hydrogen sulfide, elevated chloride in deeper formations. A comprehensive water test after drilling (typically $150–$500) will identify which treatments, if any, your well needs.
