Seawater Barrier Pilot Program

Seawater Barrier Pilot Program

The pilot program would involve the construction and operation of a series of 2-4 injection wells and one exploratory monitoring well on a relatively flat, 27,600 s.f. site on the south side of Hueneme Road. The pilot program is intended to test the feasibility and effectiveness of forming a hydraulic barrier that will prevent or substantially reduce seawater intrusion into the Upper and Lower Aquifer Systems beneath the Oxnard Plain. This would be accomplished by injecting freshwater into the Upper and Lower Aquifer Systems, which are currently below sea level, in order to form a groundwater potentiometric mound that would reverse the current landward groundwater gradient and direction of water flow, thus impeding the inland flow of seawater into the aquifer.
