Hydraulic Characteristics of the Unconsolidated Deposits of the Metro East Area, Illinois

Slug tests have been conducted on the following wells in the Metro East area

to estimate the horizontal hydraulic conductivity of the aquifer or saturated

fine-grained deposits in the vicinity of the open interval of each well.

Tests were conducted using a 10-psi (pound per square inch) rated pressure

transducer, automatic data logger and, a solid core 1.5-inch x 3.5-foot PVC slug.

A minimum of two tests were conducted in each well, consisting of at least

one falling-head and one rising-head test. The estimated hydraulic conductivity

represents the average of all test values at an individual well. Test analyses were

either by the method of Bouwer and Rice (1976) or van der Kamp (1976), as

determined by local aquifer characteristics.
