An increase in environmental awareness has come with the expansion of the hog industry in Saskatchewan. More stringent standards have been set for earthen manure storages such as a minimum of 600mm repacked clay soils and geotextile liners. However, these improved liners have done little to alleviate public concerns. In answer to this concern, a program was initiated to monitor solute migration through the liners of different hog manure storages throughout Saskatchewan. Currently, the system has been installed in three newly constructed sites and two established sites.
