Hydrogeochemical Computer Modeling of Proposed Artificial Recharge of the Upper Santa Fe Group Aquifer, Albuquerque, New Mexico
Recently, the City of Albuquerque began investigating the feasibility of artificial recharge of its underlying upper Santa Fe aquifer. This paper concerns recharge via injection wells. Proposed recharge fluids are (1) treated effluent from the Albuquerque wastewater treatment facility and (2) Rio Grande surface water. This study used the hydrogeochemical model PHREEQE to simulate subsurface injection. As a basis for comparison, simulations were also performed with data from the successful El Paso artificial recharge project. The results suggest that subsurface injection of Albuquerque treated effluent will be successful and that subsurface infiltration of Rio Grande surface waters will probably be successful. The simulations predict no significant adverse impact on water quality as a result of artificial recharge. However, other factors that may affect potability, such as trace-metal distributiory ion exchange, bacteriological content, and the presence of potential pollutants, are not considered by the model. Site-specific pilot testing and kinetics-based computer modeling are recommended to oredict the useful life of recharge facilities. Equilibrium-based models, as used in this study, can only predict whether recharge is likely to be successful. They cannot determine the potential life of a recharge facility.
