Under Construction

Our passion is to help you test your water, treat it if necessary, and to make sure your water isn't negatively affecting your health or increasing your risk of illness.

We're still setting up our web site, which will include water quality and health consultations, a water testing service, and educational resources. If you have an immediate water quality question that can't wait, click here to schedule a Water Consultation today.

Steven Spayd is the founder and president of Diagnosis Water, LLC. He is an environmental and public health scientist and hydrogeologist. He has a Doctorate (PhD) and Masters Degree in Public Health (MPH) from Rutgers University and the University of Medicine and Dentistry of New Jersey with a focus on Environmental Health. He also has a Bachelor of Science Degree in Geoscience and is a licensed Professional Geologist (PG). He recently retired from the New Jersey Department of Environmental Protection (NJDEP) where he worked in the Site Remediation Program and New Jersey Geological and Water Survey for 40 years. During his career at NJDEP he worked on a large variety of contaminated sites affecting both private wells and public supply wells. He was a member of the NJDEP Toms River Work Group which provided technical support to the Department of Health and Human Services for the investigation of childhood cancers in Dover Township, Ocean County, New Jersey. He helped lead the development and implementation of New Jersey's Well Head Protection Program. He was one of the founders of the New Jersey Private Well Consortium.

Dr. Spayd's most recent work at the NJDEP was on the geologic sources and effective water treatment for naturally occurring contaminants like arsenic and radioactive elements. He has been a leader in public health outreach to private well owners in high-risk areas. He was a key collaborator with the New Jersey Department of Health, the Centers for Disease Control, Columbia University, and Rutgers University School of Public Heath on the public health aspects of contaminated water from private wells. He has always been available to assist residents and government agencies at all levels with water quality, water treatment, contaminant transport, well hydraulics, and hydrogeologic issues. Throughout his career at the NJDEP, he has helped develop policies, regulations, and standard operating procedures regarding drinking water, ground-water protection, pollution investigation, and cleanup. He has also been an Adjunct Professor teaching Geology and Hydrogeology and has coauthored 14 peer-reviewed papers, a book chapter on arsenic in water, and several New Jersey Geological and Water Survey and NJDEP publications.
