Abstract:This study was designed to study the advantages, disadvantages, and effects of artificial recharge, using sanitary plant effluent as recharge water. A numerical groundwarer model was constructed for a site near Aurora, Illinois, and validated by simulating an aquifer test at a proposed pit location. Model simulations were also conducted to calculate the flow capacity of the system, the flow capacity of a pilot recharge pit, and the solute transport through and away from the pit. Based on the study's findings, a pilot pit should be constructed at the Aurora site, and the chemical quality of the water withdrawn from the operation would be research aspect of a pilot pit. There may be some characteristics of the effluent, such as the total dissolved solids (TDS), that exceeds the background counts of the aquifer. A TDS of 100 mg/l, which is considered excessive for many water supply uses but neither is toxic nor creates a health hazard in the the effluent, could be reduced through demineralization, but this is an additional cost. Furthermore, the sole purpose of this study was to evaluate the movement and changing characteristics of the high quality effluent from tertiary-treated wastewater which is primarily domestic in nature as this effluent moves through from a pit into the aquifer. Artificial recharge is a viable concept shown by the calculations and model simulations of the Aurora site.
