SUMMARY/DISCUSSION:
The Monterey County Water Resources Agency (MCWRA) is responsible for maintaining the supplemental irrigation wells as part of the Castroville Seawater Intrusion Project (CSIP). CSIP wells 14L03 and 16G01 have not been operated for years either due to well casing deterioration or to leakage of seawater-intruded groundwater along the outside of the well casing. Attempts to repair the wells were unsuccessful. Both wells are impacting the water quality of the Pressure 400-Foot Aquifer. Therefore, the proper destruction of the wells is necessary for preventing the flow of seawater-intruded ground water from the Pressure 180-Foot Aquifer to the Pressure 400-Foot Aquifer.
