NOAA’s Monterey Bay National Marine Sanctuary (MBNMS) has released a draft Environmental Assessment (EA) of a proposal by California American Water to develop and operate a temporary slant test well for obtaining information about the geologic, hydrogeologic, and water quality characteristics of coastal aquifers. It is now valuable for public review and comment until July 26, 2014 . The data obtained during the 24-month testing and monitoring phase would be used to facilitate the planning and final design of a proposed subsurface slant well intake system and desalination plant to serve as the primary future water supply source of the Monterey Peninsula.
The slant test well would be drilled in the coastal foredune area of the CEMEX sand mining facility and would extend diagonally under the floor of the Pacific Ocean into the submerged lands of MBNMS. The slant test well would pump up to 2,500 gallons per minute from the underlying aquifers for a two-year operational testing and monitoring period. The pumped water, consisting of untreated, brackish groundwater, would be discharged into MBNMS via an existing ocean outfall pipeline extending approximately 2 miles offshore.
The project includes the development and operation of four to 12 temporary vertical monitoring wells to evaluate the hydrogeologic response to pumping activities at the slant well site. Upon completion of the testing and monitoring activities, the slant test well, vertical monitoring wells, and all appurtenant facilities would be decommissioned, excavated, and removed, and the site would be restored to its original condition.
The test project requires approvals from MBNMS and other state and federal agencies for the proposed drilling activities and discharge of untreated groundwater into MBNMS.
