25 The yield of a bedrock aquifer depends on its hydraulic characteristics and the nature of the overlying deposits. Shale and glacial till act as aquitards, restricting recharge to County Road 1650 S underlying bedrock aquifers. However, fracturing and/or jointing may occur in aquitards, 30 29 28 30 29 27 26 25 26 which can increase recharge to the underlying aquifers. Hydraulic properties of the 28 27 bedrock aquifers are highly variable. Most of the bedrock aquifers in the county are Kankakee Fish under confined conditions. In other words, the potentiometric surface (water level) in County Road 1700 S and Wildlife Area most wells completed in bedrock rises above the top of the water-bearing zone.

These shales are commonly considered an aquitard; County Road therefore, the system is an extremely limited groundwater resource. State Road & US Highway h c t i LaPorte County has a complex glacial history and was subjected to multiple glacial D 10 Interstate 7 7 8 9 r 12 advances from the north and northeast resulting in glacial sediment deposits completely 8 9 10 e 11 n t covering the county. The thickness of unconsolidated sediments ranges from over 400 i Kankakee Fish La P feet in the northwest to approximately 50 feet in the southwest corner of LaPorte County. Municipal Boundary

a 17 17

13 18 in LaPorte County only the Ellsworth and Antrim Shales are present. The Ellsworth
R

t Shales consist primarily of gray-green shale with limestone or dolomite lenses in the
n u
o upper part and alternating beds of gray-green shale and black-brown shale in the lower C County Road 2100 S part. The underlying Antrim Shales consist of brown to black non-calcareous shale in the Runnymede upper part and black to brown non-calcareous shale with calcareous shale, limestone, and Lake & River 21 sandstone present in the lower part of the unit. This system is overlain by unconsolidated deposits ranging in thickness from 50 feet to over 400 feet. 19 20 24 20 21 22 23 19 Because of the availability of the overlying unconsolidated resources, few water wells have been completed in the Coldwater, Ellsworth, and Antrim Shales Aquifer System in County Road 2200 S LaPorte County. However, this aquifer system is capable of meeting the needs of some domestic users in this county. Domestic well yields are commonly less than 10 gallons 29 per minute with dry holes likely. Well depths range from 66 to 200 feet deep and static 26 30 water levels typically range from 10 to 80 feet below the land surface. The amount of 30 29 27 421 28 25 rock penetrated in this system ranges from 50 to 62 feet. There are no registered significant groundwater withdrawal facilities in LaPorte County.
Since the permeability of shale materials is considered low and the overlying Kankakee 35 36 unconsolidated deposits are thick, susceptibility to contamination introduced at or near River Swampland R. 4 W. R. 3 W. the surface is low. 34 31 Wilders 33 32
