CODE	DESCRPTION

1	Yields of 3-10 gallons per minute can be developed. Ground-water obtained from the Berea Sandstone. Although this formation covers a great deal more area than shown, its thickness and recharge potential limit productivity to isolated zones. Long term safe yields average less than 10 gallons per minute even though some wells report higher initial yields.
2	Yields of 3-10 gallons per minute can be developed. Ground-water obtained from thin discontinuous sand and gravel deposits interbedded with fine sandy clay. Well yields range from 3 to 10 gallons per minute although a few wells encountering thicker sand and gravel deposits may yield as much as 20 gallons per minute. If permeable deposits are not encountered, drilling into the underlying shale is not productive.
3	Yields seldom exceed 3 gallons per minute. Impermeable deposits of clay overlying shale yield less than 3 gallons per minute. Dry wells are not uncommon. If small supplies are developed additional storage may be necessary to supply peak demands. Drilling deeper usually results in brackish or oily water.
