SFPUC June 10, 2020 Page 14 <br /> All laboratory analyses should be conducted at a certified mercury analytical lab. If SFPUC lab <br /> is not able to analyze samples, an alternative qualified lab is: <br /> Caltest Analytical Laboratory <br /> 1885 North Kelly Road, Napa, CA 94558 <br /> Main: 707-258-4000 <br /> Todd—Albertson@CaltestLabs.com <br /> Data Handling <br /> The laboratory is responsible for preparing analytical laboratory reports that are reviewed and <br /> approved by the laboratory's Quality Assurance Officer. A written report should be prepared by <br /> the analytical laboratory documenting all the activities associated with each sample analysis. At a <br /> minimum, the following should be included in this report: <br /> • Results of the laboratory analysis and laboratory quality assurance/quality control results; <br /> • All protocols used during analyses; <br /> • Chain-of-custody(COC) procedures; and <br /> • Discussion of any deviations from the approved methods. <br /> Sample analytical results from the lab should be received by the SFPUC Regulatory Specialist, <br /> water quality staff and the Chief Stationary Engineer. The reports should be saved electronically <br /> by stationary and maintenance engineering. Multiple staff should review analytical results for <br /> anomalies, qualify data as necessary, and then save the data report. The Chief Stationary <br /> Engineer should retain indefinitely all original field logs, photos, COC forms and lab reports. <br /> References <br /> AEW Engineering, Inc. (2018).
