Steven Spayd, PhD, MPH, PG is a hydrogeologist and public health scientist recently retired from NJDEP where he worked in the Site Remediation Program and New Jersey Geological Survey for 40 years. He worked on many sites with groundwater and well contamination with a focus on water quality and hydrogeology. Investigations ranged from Superfund and radioactive waste to leaking tanks and road salting with an emphasis on sites contaminating public supply wells and private wells. Steve helped design New Jersey’s Well Head Protection Program, was a founding member of the New Jersey Private Well Consortium, and provided technical support for regulation development. His latest work at NJDEP was on the sources and effective water treatment for geogenic contaminants, like arsenic and radionuclides, as well as public health outreach to private well owners in high-risk areas. He has also been an adjunct professor teaching geology and hydrogeology and has coauthored 17 peer-reviewed papers, a book chapter on arsenic in groundwater, and several NJ Geological Survey and NJDEP publications. Currently, he is the Founder of a startup water consulting business called Diagnosis Water, LLC.
