The Water Replenishment District of Southern California (WRD) is responsible for managing and replenishing both the West Coast and Central Coast groundwater basins. In the West Coast Basin, a significant plume of saline groundwater (saline plume) with elevated total dissolved solids (TDS) has been trapped in the Gage, Silverado, Lynwood, and Lower San Pedro (equivalent to Sunnyside) aquifers because of historical seawater intrusion and the subsequent implementation of two injection barriers. To fully utilize the West Coast Basin, WRD initiated a Regional Brackish Water Reclamation Program (Program) to evaluate ways to remediate the trapped saline plume. Program goals include remediation in the form of treating the saline plume so that it produces potable water and discharge of waste streams generated (mostly high-salinity brine) in the treatment process. As a part of the Program, WRD has initiated a regional planning study to evaluate the feasibility of remediating the saline plume, working with seven additional stakeholders (known as the Stakeholder Group). The Stakeholder Group that participated in the Feasibility Study expressed interest in treating the saline plume or receiving the treated water, or both, as part of the Program. As the Program progresses and project options are refined, additional Stakeholders could be included in the Stakeholder Group through various forms of Program participation.
