Hydraulic conductivity test results for three field clays exposed to two inorganic chemicals are documented. The hydraulic conductivities of clays exposed to waste chemicals is an important consideration in the selection of a liner material for a hazardous waste containment facility. In the research project, the hydraulic conductivities of three field clays; White Store, Hoytville, and Faceville permeated with ferric chloride (500 mg/l) and nickel nitrate (50 mg/l & 300,000 mg/l) were determined using both fixed and flexible-wall permeameters. The effectiveness of five laboratory tests for predicting the effect inorganic chemicals may have on clay particles were also evaluated. Results indicate that at the concentrations tested, neither ferric chloride nor nickel nitrate significantly altered the hydraulic conductivities of the three clay soils. The results from the predictive tests are seen to be inconclusive. (Copyright (c) 1987, ASCE.)
