In northern and western Jackson County, most wells in the valley bottoms are located in limestone formations and are adequate for domestic use. In the central and eastern parts of the county, most drilled wells in the valley bottoms are set in sandstone and usually produce enough water for domestic use. Most wells on hillsides produce enough water for domestic use, and about half the wells drilled on hilltops and ridges are adequate for domestic use. In far eastern Jackson County, water becomes more scarce, with only some wells in the valleys and a few well on the ridges able to produce enough water for domestic use. Most well water in Jackson County is moderately hard and contains noticeable amounts of iron. Some wells in the Station Camp Creek valley produce very hard water that may contain hydrogen sulfide in objectionable quantities. Salt water can also be found at depths of 100 feet and greater below the principal valley bottoms in eastern, northern and western Jackson County. A few springs supply enough water for domestic use. Most springs yield less than 5 gal/min except in the northern and western parts of the county where limestone springs producing up to 100 gal/min can be found.
