Wastewater was applied to three soils to determine the sealing effect or change in hydraulic properties. Saturated conductivities were measured weekly over a 40-week period. For the Lester clay loam and Waukegan silt loam, saturated conductivities of the soils was less than the saturated conductivities of the wastewater seal. In Hubbard loamy sand, an immediate seal was found due to the application of wastewater. The saturated conductivity continued to decrease for the 12-week period during the wastewater application. When wastewater application terminated, an immediate increase in the saturated conductivity occurred. Following the end of wastewater application, the saturated conductivity became greater than in a normal soil, indicating an improvement in hydraulic properties.
