This is a message from the State Water Resources Control Board.










In response to requests from the Division of Drinking Water, the California Department of Fish and Wildlife, and the Los Angeles Regional Water Quality Control Board, the Environmental Laboratory Accreditation Program (ELAP) updated its field of accreditation (FOA) offerings for drinking water, non-potable water, and wastes analysis. ELAP revised four FOA Tables: 105, 108, 117, and 133. To obtain accreditation for any of these newly added FOAs, laboratories must submit a complete application package, including a completed on-site assessment, approved corrective action plan, and acceptable proficiency testing scores. Additional application requirements can be found on ELAP's Application webpage. Table 105: Semi-volatile Organic Chemistry in Drinking Water At the request of the Division of Drinking Water, ELAP now offers PFAS analysis using EPA 533. Currently, the Division of Drinking Water’s issued Orders require the use of EPA 537.1, however, future Orders being considered may use EPA 533. It is the laboratory’s responsibility to confirm that the method utilized meets its client’s need
