In the northern two-thirds of Butler County, most wells from depths of less than 300 feet are adequate for a domestic supply. Wells located in the Green River flood plain can produce as much as 100 gallons of hard water per minute. Most wells obtain their water from thick sandstone layers and will yield as much as 60 gallons per minute. In the southern third of the county, only a few wells yield enough water for a domestic supply. In the central section of the county, moderately-mineralized water may be obtained from sandstone formations at depths of 1,200 feet. Generally, ground water is hard to very hard and iron and salt may be present in objectionable amounts. Often groundwater becomes saltier with depth. |
