ABSTRACT: The potential use of municipal biosolids as a replacement for clays and silts in the development of a capillary barrier cover for reactive mine tailings is evaluated at a laboratory scale. Low saturated hydraulic conductivities were observed in biosolids during material characterization (k = 4.21 x 10 -7 cm/s), and high degrees of saturation have been shown to be maintained at elevated suctions indicating high moisture retention properties. Numerical modelling results indicate a robust saturated layer can be maintained over a 91-day simulation. Laboratory scale column tests will be analyzed and compared to the findings of simulations.
