In support of the Santa Clara Valley Water District policies to expand the use of recycled water and to protect the groundwater basin, a multi-year study was initiated by the District in 2007 to evaluate potential groundwater impacts from the expanded use of recycled water for irrigation in the Santa
Clara and Llagas subbasins, and to develop water quality standards and best management practices to minimize impacts to groundwater quality. Data and discussion is presented on the scope of the evaluation, literature and data review, attenuation modeling, a laboratory bench test, a field pilot study, evaluation of potential impacts, soil aquifer treatment capacity, calculation of groundwater degradation potential, and ongoing monitoring recommendations.
