More than three-quarters of the wells drilled in valley bottoms and almost three-quarters of the wells drilled on hillsides are adequate for domestic needs. Only some of the wells on hilltops and ridges are adequate for domestic needs. Drilled wells more than 200 feet deep in valleys may yield enough water for small municipal or industrial supplies. Groundwater obtained from most wells is moderately hard and contains noticeable amounts of iron. In the northwestern quarter of the county, salty water may be found in wells less than 100 feet below the level of the principal valley bottoms. In the rest of the county, salty water in wells probably will not be found shallower than 200 feet below the level of the principal valley bottoms. A few springs supply enough water for domestic use; most produce less than 5 gallons per minute. |
