Determination of diffusion and adsorption coefficients for some contaminants in clayey soil and rock: Laboratory determination and field evaluation

Miscellaneous:

Abstract

A laboratory diffusion test determination of diffusion coefficient (D) and adsorption coefficient (K{sub d}) for various inorganic and organic species in a saturated, undisturbed, clayey soil is presented. Diffusion tests conducted for inorganic species (Cl{sup {minus}} , Na{sup +}, K{sup +}, Mg{sup 2+}, and Ca{sup 2+}), involved placing domestic landfill leachate on top of a layer of clay and allowing the chemical constituents to diffuse into the soil. The mathematical model POLLUTE was then used to back-figure (D) and (K{sub d}) for each species. Diffusion tests conducted for organic species (acetone, 1,4-dioxane, aniline, chloroform, and toluene), involved diffusion of the species from a source solution placed on one side of a clay plug, into a distilled water collector solution on the opposite side. Using POLLUTE, D and K{sub d} were then determined by fitting the measured concentration variation with time in both the source and collector solution. In addition to the laboratory study, an investigation of inorganic contaminant diffusion below an existing industrial landfill site was conducted by analyzing soil and pore water specimens from the clay layer underlying the waste. Concentration profiles for Cl{sup {minus}}, So{sub 4}{sup 2{minus}}, Na+, Ca{sup 2+} and Mg{sup 2+}, showed above background levels to  More>>

Concentration profiles for Cl{sup {minus}}, So{sub 4}{sup 2{minus}}, Na+, Ca{sup 2+} and Mg{sup 2+}, showed above background levels to a depth of 1.4 m below the waste after 11 years of migration. K{sup +}, B, and NH{sub 3}-N profiles, penetrated to less than 0.5 m below the waste. Field profiles for Na{sup +}, K{sup +}, Cl{sup {minus}}, and SO{sub 4}{sup 2{minus}} were then compared with those predicted using POLLUTE with D and K{sub d} values obtained from diffusion tests using leachate and natural uncontaminated clay from the site. Finally, a laboratory diffusion test determination of Cl{sup {minus}} diffusion coefficient in samples of intact, saturated shale and mudstone is presented.}
