Independent Advisory Panel
The Advanced Water Purification Program (AWP) has an Independent Advisory Panel (IAP) that advises the program team to ensure an unbiased and thorough examination of the proposed water purification efforts.
This panel of independent experts helps ensure that all important program components are thoroughly reviewed and analyzed.
Below is a list of the IAP member bios and experience as experts in the fields of water and wastewater technology, public health, epidemiology, toxicology, water quality, economics and environmental science.

Jim Crook is an environmental engineer with more than 35 years of experience in state government and consulting engineering arenas, serving public and private sectors in the U.S. and abroad. He has authored more than 100 publications and is an internationally recognized expert in water reclamation and reuse. He has been involved in numerous projects and research activities involving public health, regulations and permitting, water quality, risk assessment, treatment technology, and all facets of water reuse. Crook spent 15 years directing the California Department of Health Services’ water reuse program, during which time he developed California’s first comprehensive water reuse criteria. He also spent 15 years with consulting firms overseeing water reuse activities and is now an independent consultant specializing in water reuse. He currently serves on several advisory panels and committees sponsored by NWRI and others. Among his honors, he was selected as the American Academy of Environmental Engineers’ 2002 Kappe Lecturer and the WateReuse Association’s 2005 Person of the Year. Crook received a B.S. in Civil Engineering from the University of Massachusetts and both an M.S. and Ph.D. in Environmental Engineering from the University of Cincinnati.

Dan Gerrity has been an Assistant Professor in the Department of Civil and Environmental Engineering and Construction at the University of Nevada, Las Vegas, since 2012. His research interests include water and wastewater treatment (biological, physical, and chemical treatment processes), potable reuse (including water quality, public health, and public perception), and trace organic contaminants (such as pharmaceuticals and endocrine disrupting compounds), among others. Prior to joining the university, he served as a Senior Engineer at Trussell Technologies, Inc., an environmental engineering consulting firm, where he was a team member for the project “WateReuse 11-02: Equivalency of Advanced Treatment Trains for Potable Reuse.” Gerrity received a B.S. in Civil Engineering and both an M.S.E. and Ph.D. in Environmental Engineering from Arizona State University.
RICHARD GERSBERG, Ph.D.
Professor and Head, Division of Occupational and Environmental Health
Graduate School of Public Health
San Diego State University (San Diego, California)
Rick Gersberg serves as a Professor and Head of the Division of Occupational and Environmental Health at San Diego State University. He specializes in water quality research and limnology, and has broad experience working with both chemical and microbiological pollutants and risk assessments. Prior to joining the California State University system in 1986, he was Director of Research for the San Diego Region Water Reclamation Agency and both a Project Manager and Environmental Consultant for Ecological Research Associates. Among his most recent activities, Gersberg was a member of the CALFED Bay-Delta Authority (CBDA) Science Program, in cooperation with California Sea Grant. He has also been actively involved in projects on the effects of global climate change on the coast of San Diego, California, and risk assessment regarding consuming fish and ocean recreation in Imperial Beach, California. He is currently the Principal Investigator of an EPA and SCERP-funded study to use polymerase chain reaction (PCR) methods do quantitate the levels of hepatitis A virus and enteroviruses in the recreational ocean waters near the U.S-Mexico border, and to examine the removal of these viruses (and selenium) by constructed wetlands treating the contaminated New River before it enters the Salton Sea, California. Gersberg received a B.S. in Biology from the City College of the City University of New York, an M.S. in Biology from the University of Houston, and a Ph.D. in Microbiology from the University of California, Davis.
