DESCRPTION

1

5 - 25 gallons per minute. Sand and gravel deposits, principally beneath the floodplain of the East Branch of the Chagrin River, yield 5 to 25 gallons per minute at depths of as much as 200 feet. Test wells may prove the existence of more than 100 gallons per minute from gravel packed screened wells.

2

5 - 25 gallons per minute. Shallow permeable fine sand, and sand and gravel, serve as excellent recharge to the underlying sand and gravel acquifer developed at depths of as much as 45 feet. Specific methods of construction provide means for the development of greater yields.

3

3 - 10 gallons per minute. Wells developed in fine sand, and sand and gravel, at depths of less than 75 feet yield up to 10 gallons per minute. Specialized methods for well development may produce as much as 30 gallons per minute.

4

3 - 10 gallons per minute. Buried valley deposits consisting of thick layers of clay and/or fine sand, and silt interbedded with thin lenses of sand and gravel. Wells drilled in southeast Kirtland Township yield 3 to 10 gallons per minute at depths of as much as 150 feet. Shallow deposits in Concord Township yield 5 gallons per minute at depths of less than 65 feet.

5

3 - 10 gallons per minute. Sandstone and sandy shale yield 3 to 10 gallons per minute at depths of 40 to 150 feet.

6

Less than 3 gallons per minute. Very shallow permeable silt, fine sand, and sand with some gravel, overlying thick clay or shale yields less than 2 gallons per minute to drilled wells. Athough greater yields are available from specialized methods of construction, the shallow deposits are very susceptible to surficial contamination from leaching tile fields, dry wells, etc. used for the disposal of sanitary wastes.

7

Less than 3 gallons per minute. Non-water bearing glacial deposits, basically clay, overlying shale or shaly sandstone yield less than 2 gallons per minute to drilled wells. Very poor area for the development of ground water supplies. Dug wells, additional storage and/or cisterns are common.
