Recommendation
Adopt the Resolution AUTHORIZING THE CHIEF EXECUTIVE OFFICER TO NEGOTIATE AND EXECUTE A FINANCIAL ASSISTANCE PLANNING GRANT AGREEMENT WITH THE CALIFORNIA STATE WATER RESOURCES CONTROL BOARD FOR REVERSE OSMOSIS CONCENTRATE MANAGEMENT.
Body
SUMMARY:
On October 25, 2016, the Board approved Agreement No. A4034G with GHD, Inc. (GHD) for Consultant Services for the Reverse Osmosis Concentrate (ROC) Management Project, Project No. 91101004 (Consultant Agreement). The Project will develop ROC management plans that will provide recommendations for implementation of a county-wide solution to ROC management, taking into consideration the unique characteristics and limitations at potential advanced water purification facilities (AWPFs). The scope of work includes testing of contaminants of emerging concern (CECs) that may be present in ROC, as well as pilot treatment of identified CECs by advanced oxidation processes and engineered treatment cells. The testing and piloting portion of the project will be carried out in partnership with the San Francisco Estuary Institute (SFEI), University of California at Berkeley (UCB), and Stanford University.
A key study component includes the design, installation and operation of above-ground pilot-scale, engineered treatment cells to test the performance of wetland systems and oxidative pretreatment, and to evaluate their cost effectiveness and beneficial use. An important milestone was completed in May 2017 with the construction and subsequent seeding to produce a functioning pilot engineered treatment system. Research to date has included bench-scale studies to assess the dose of oxidants, oxidant efficacy in degrading targeted ...
