Puente Valley Operable Unit Intermediate Zone Remedy

Puente Valley Operable Unit Intermediate Zone Remedy

The proposed project consists of the construction and operation of six new extraction wells, water conveyance pipelines, and treatment system improvements associated with implementation of the remedy of the IZ in the PVOU. The proposed extraction wells will be approximately 10-inches in diameter and extend to approximately 400 feet below ground surface. The conveyance pipeline would range from 6-to 12-inch diameter pipe totaling approximately 2 miles in length. The proposed wells and pipeline system also include construction of appurtenant structures (e.g., maintenance/access holes, flow meters, values, and/or vaults). The proposed treatment system involves the modification of the existing San Gabriel Well B7C Treatment Facility (Air Stripper) to incorporate conveyance of the untreated IZ water to the air stripper inlet.
