Physical Characterization of Water Treatment Plant Residual and Top Soil Mixtures


Disposal of water treatment plant residuals is not economically feasible due to their high moisture contents, high compressibilities and very low shear strengths. This paper evaluates the physical and geotechnical characteristics of water treatment residual-top soil mixtures for beneficial reuse in construction and land application. Index, compaction, consolidation, strength and durability tests were performed in accordance with the relevant ASTM standards. It was observed that the plasticity of the mixtures decreased and handling (compaction) and other engineering characteristics improved due to the addition of top soil to residuals. There is a potential for these mixtures to be used as liner material for landfills.
