indicators of seawater intrusion - Seasidebasinwatermaster.org

FINAL DRAFTThe following activity shall be initiated within 90 calendar days of the Watermaster Board adopting recommendations from the previous activities:• Modify pumping to achieve the desired groundwater gradient.Groundwater pumping at the most influential production wells should bemodified to achieve the groundwater gradient calculated above.ACTION 5: FOCUS SUPPLEMENTAL SUPPLIES TO HALT AND REVERSESEAWATER INTRUSIONWhen a supplemental water supply becomes available for Seaside GroundwaterBasin replenishment, the Watermaster will seek to have the supplemental waterused strategically to protect the Seaside Groundwater Basin from furtherseawater intrusion, and to restore the Basin to pre‐seawater intruded conditions.Supplemental supplies should be used to both offset pumping that causes theobserved seawater intrusion, and to raise groundwater levels to reverse seawaterintrusion.Seawater Intrusion Response PlanNovember 19, 2008 - 18 -
