Groundwater resources in Marion County are limited. Wells located in the larger valley bottoms throughout the county will produce enough water for a domestic supply, except during dry weather. In upland areas (80 percent of the county), most drilled wells will not produce enough water for a dependable domestic supply, unless they are drilled along drainage lines, in which case they may produce enough water except during dry weather. Throughout the county, groundwater is hard or very hard, and may contain salt or hydrogen sulfide, especially at depths greater than 100 feet. |
