California State Polytechnic University, B.S., 1972, Environmental Microbiology

Employment History:

Environmental Microbiology Consultant July 2001 to Present.

Since July 2001, have accepted consultant assignments with special focus on groundwater issues

associated with groundwater recharge, microbiological methods development and biosolids

utilzation and research.

County Sanitation Districts of Los Angeles County, San Jose Creek Water Quality Laboratory,

Whittier, CA. - April 1971 to July 2001 (Retired).

Primary experience is in environmental research and program management, specifically in the

public health aspects of water reclamation, water reuse and waste solids recycling. Thirty years

experience at the Districts' in environmental microbiology. During the period from 1971 to 1980

advanced through professional positions to level of Laboratory Supervisor, with progressively

increasing program management responsibilities. Duties included coordinating activities of

scientific staff of nine microbiologists and technicians with engineering projects and research

studies. Represented agency in regulatory and legal issues related to public health aspects of

wastewater treatment, biosolids utilization and water reuse. Responsible for managing

microbiology phase of research programs in public health aspects of water reclamation and reuse,

with emphasis on research related to groundwater recharge for indirect potable reuse, and sludge

utilization, including work in areas of indicator and pathogenic bacteriology, parasitology,

mycology, virology and toxicology. Assignments included managing and coordinating

microbiological portions of funded multi-agency research effort examining sludge disposal

options in Southern California and managing portions of funded research examining health

aspects of water reuse via groundwater recharge. Was principal investigator and project manager

for USEPA funded 26-city national study of occurrence of pathogens in distributed and marketed

sludge products. Was Co-PI for microbiological portions of large southwestern U.S. study on

soil aquifer treatment for sustainable water reuse. Have served as a consultant, program reviewer

and workshop participant for USEPA in areas of biosolids research, recreational water quality,

and development of Groundwater Rule. Presented work at 1997 EPA workshop (Cincinnati)

"Analytical Methods for Monitoring Microbes in Groundwater" on development of a large

volume enrichment method to detect phage in groundwater, which was later further developed as

Method 1601 for GWR testing. Have served on numerous research advisory/review committees

for Water Environment Research Foundation, American Water Works Research Foundation and

Water Reuse Foundation sponsored projects. Member of Standard Methods Committee in

Microbiology for 19th, 20th and 21st editions, specifically on Joint Task Groups for Quality

Assurance, Pathogenic Bacteria and Bacteriophage. Served as reviewer for National Research

Council 2002 report on Biosolids Applied to Land. Have been invited University guest lecturer

and served as expert witness in reclaimed water groundwater recharge litigation. Retired from

CSDLAC July, 2001.

Envirogenic's Company Aerojet-General Corporation, El Monte, CA. - 1969 to 1971.

Senior Technician - Worked in the membrane research department on reverse osmosis membrane

development and evaluation. Duties included running and maintaining the membrane testing

laboratory and associated equipment. Also included devising and designing equipment and

experiments for special water projects. Routine water analyses were performed by instrumental

and wet chemical methods.
