Lily Sanchez


I have 30 years of direct experience in drinking water analytical testing and compliance. Over last eleven years, I have served as a Supervising Chemist of the Orange County Water District laboratory in the organic section. My responsibilities are providing leadership, solving problems, training staff, implementing method development, and improving existing methods and quality assurance. I have over eight years of working experience with PFAS analysis EPA methods: 537, 537 REV 1.1 and 537.1

Over the years, I have worked on various instruments including HPLC, GC, GCMS, and LCMSMS. Since 2007, my focus regarding analytical testing has been on the development of LCMSMS analytical methods for emerging contaminants such as CECs, PPCP, PFOA/PFOS and UCMR. In addition to participating in all 4 UCMR programs, I have been project leader for UCMR 2, 3, and 4.

I received a Bachelor in Chemistry from California State University Long Beach. I am a member of these professional organizations: ASMS, BCES, and TNI.
