Ozarks (Rural)
Karst geology shapes springs, sinkholes, and groundwater here
The county's karst limestone and dolomite create springs and sinkholes and mean groundwater can move fast, which matters for wells, septic siting, and contamination risk on rural property.
A sinkhole in Texas County is not just a dip in the ground. Much of this Ozark county sits on karst, where water slowly dissolves limestone and dolomite. Over time, that kind of rock can form springs, sinkholes, losing streams, and caves.
Karst makes rural property homework more serious. Groundwater can move fast underground, so waste dumped in a sinkhole or a failing septic system can reach a spring or well sooner than a person expects. Around Houston, Licking, and the county roads between them, a good land walk includes looking for low spots, drainage paths, and signs of old sinkholes.
DNR’s karst and sinkhole guidance is the place to start for the ground under your land. Before you trust a well, place a septic system, or ignore a sinkhole, learn how water moves through the rock.
