A Bit About Jeff

Dr. Dagdigian is the owner and Managing Principal Environmental Scientist of Waterstone Environmental, Inc. He is an expert in fate and transport analysis for chemical compounds including petroleum hydrocarbons and fuels, chlorinated hydrocarbon solvents, heavy metals, and other persistent chemicals in the subsurface.


As a Ph.D. chemist with over 33 years as a consulting environmental scientist, he has evaluated environmental issues on hundreds of properties where petroleum hydrocarbons, chlorinated solvents, heavy metals and other contaminants were released during historical industrial or commercial uses. Dr. Dagdigian has performed forensic evaluation of chemicals within soil, soil gas, and groundwater to help understand the source of the contamination and, sometimes, the age of contamination. Dr. Dagdigian has designed hundreds of sampling plans to define the extent of impacted areas and to identify the sources on contaminated sites. He has helped assign responsibility to involved parties; and has designed and performed remediation leading to “no further action” decisions by oversight agencies.


Dr. Dagdigian has been an instructor at UCI’s extension campus for over 17 years. During that time he has taught courses dealing hazardous waste chemistry and site characterization and auditing. Dr. Dagdigian is qualified expert witness with significant experience testifying for both plaintiffs and defendants.
