A laboratory permeability testing program was designed and performed to evaluate the effect of an acid liquor on two alternative materials planned for use in a compacted soil lining to minimize seepage loses from a phosphogypsum storage area. The alternative materials considered for use in the compacted soil lining included (1) on-site natural clayey soils and (2) on-site silty sands mixed with commercial bentonite (Volclay saline seal, No. 100). The acid liquor has a pH of 2.2 and is high in calcium, calcium oxides, sodium, chloride, and sulphate. The test results indicated that the acid liquor permeant resulted in lower permeabilities of the clayey soils than with tap water permeant. The tests on the commercial bentonite-silty sand mixtures with acid liquor permeant indicated that the permeability increased with time.
