The study examined hydrogeologic environments as related to groundwater flow systems, recharge and the reuse of wastewaters, Parameters used to delineate areas most suitable for wastewater reuse include thickness of unconsolidated material, thickness of unsaturated material, regional slope and whether or not the land is being irrigated and farmed. This project has consisted of four parts: (1) An evaluation and application of methods for delineating large areas which can be safely used for the terrestrial disposal of wastewater; (2) An examination of chemical changes in soil properties resulting from the application of wastewater, particularly sweet corn canning process effluent; (3) An investigation of flow system in a mountain valley, including the application of a mathematical model to the ground-water flow system in order to evaluate its contribution to the hydrologic budget of the valley; and (4) Investigation of the effect of a terrestrial disposal operation on soil water and ground water in the vicinity of a sweet corn canning operation near Buhl, Idaho.
