DESCRPTION

01

Yield 300 or more gallons per minute. Best ground-water area in Cuyahoga County. Permeable sand and gravel deposit traversed by Mill Creek. Wells may yield as much as 1500 gallons per minute. Suitable for municipal and large industrial well field development.

02

Yield 100 - 300 gallons per minute. Permeable sand and gravel deposits interbedded with silt and clay lie in a buried valley. Yields of as much as 250 gallons per minute are available where sufficient coarse material is found. Exploratory drilling may be required to locate such deposits.

03

Yield 25 - 100 gallons per minute. Ground water obtained from buried valley deposits of sand and gravel beneath the clay and silt. Wells encountering permeable deposits may yield as much as 100 gallons per minute. Adequate domestic and small subdivision supplies may be available from relatively shallow wells less than 100 feet in depth.

04

Yield 25 - 100 gallons per minute. Ground-water supplies developed from the Sharon Sandstone encountered at depths less than 75 feet beneath land surface. Wells will produce sustained yields of as much as 40 gallons per minute. Greater yields may be available for short periods of intermittent pumping.

05

Yield 10 - 25 gallons per minute. Ground water obtained from buried valley sand and gravel deposits of limited thickness and extent. Wells developed in permeable deposits may yield 10 to 25 gallons per minute. Wells not encountering those deposits must be drilled into the underlying bedrock.

06

Yield 10 - 25 gallons per minute. Ground water from the Sharon Sandstone. Yields from 10 to 25 gallons per minute may be obtained at less than 50 feet; however wells of 200 feet or more have been recorded.

07

Yield 10 - 25 gallons per minute. Ground water developed in the Berea Sandstone or Cuyahoga Group. Average well depth is less than 50 feet..

08

Yield 3 - 10 gallons per minute. Ground water obtained from Cuyahoga Group or Chagrin, Ohio, and Bedford Shales. The 3 to 10 gallons per minute aquifer may be encountered less than 3 feet below land surface.

09

Yield 3 - 10 gallons per minute. Buried valleys contain 200 to 300 feet of fine sand, silt, and clay. Drilled wells yield meager supplies unless encountering thin, isolated sand and gravel lenses.

10

Yield less than 3 gallons per minute. Impermeable deposits, basically clay overlying shale or shaley sandstone, provide a very poor area for even minimal domestic supplies. Brackish water and dry wells are common. Storage is necessary to supply peak demands.
