Desalination Plant Infiltration Well Monterey Bay–Sand City, CA

The City of Sand City, California constructed a desalination plant to convert brackish groundwater from the ocean/groundwater interface into potable water for residential and commercial use. Brackish water is pumped from vertical wells to supply the plant. The discharge from the plant has the approximate salinity of seawater but environmental constraints made it difficult to obtain permitting to use a surface or subsurface outfall to discharge the brine directly to the ocean.
