I have 40 years of experience and specialize in the field of chemical and environmental issues with specific knowledge in the areas of equipment engineering, best practices in wastewater treatment and equipment use, and compatability. I have published on such topics as waste minimization at electronics and metal finishing facilities, wastewater treatment systems, and employee safety and health issues. I have testified on acts and omissions disclosed by an equipment supplier, wastewater treatment systems and explaining analytical data to a jury.
