Throughout 90 percent of the county, most wells from depths of less than 300 feet are adequate for a domestic supply. Wells located in the Green River floodplain 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 southwestern corner of the county, only a few wells yield enough water for a domestic supply. In a small localized area north of Earles, most wells produce less than 100 gallons per day, far less than is needed for a domestic supply. In the northern and eastern parts of the county, moderately mineralized water may be obtained from deep sandstone formations at depths of 1,200 feet. Generally, groundwater is hard to very hard, and iron and salt may be present in objectionable amounts. Often, groundwater becomes saltier with depth. |
