Bill Sothern is a nationally recognized authority in indoor environmental health. As a Certified Industrial Hygienist (CIH), Bill is a member of a small group of expert environmental professionals trained and qualified by rigorous testing through ABIH. Combining his training and extensive experience, Bill works to anticipate, recognize, evaluate and control environmental contaminants that can harm human health. His received his Doctorate in Public Health from CUNY where he focused on the associations between exposure to contaminants in indoor environments and respiratory disease outcomes among adults, children, and infants.In 1993, Bill founded Microecologies, Inc. to provide environmental inspections and clean-up solutions for clients in the metro New York area. During the past twenty six years, he has conducted and/or supervised health-based investigations for over 10,000 clients and has written scopes of work describing the remediation/engineering work necessary to eliminate the hazards identified, as well as provided project monitoring services on many projects. Bill and his staff are qualified and experienced in all aspects of HVAC mechanical hygiene, air filtration, fresh air and exhaust ventilation, water damage and mold assessment and remediation, lead paint inspections and risk assessments, environmental toxicology, chemical vapor and microbial sampling and analytical methods, and contaminant source identification and control. Bill is a trusted expert who conducts investigations and designs engineering solutions for residential clients (often referred by allergists, pulmonologists, and other physicians), commercial clients (including office managers, architects, HVAC engineers, property managers, and construction contractors), and industrial clients.Bill is also actively involved in community health issues, including his collaborations with the NYC DOHMH (mold and asthma issues), the Mount Sinai School of Medicine (lead issues), the US Green Building Council (building code issues), the National Institute for Environmental Health Sciences (flooding issues), CUNY/University of Havana (asthma in Cuba issues), the Natural Resources Defense Council (NYCHA issues), and the WHO and HUD (mold issues).Bill has developed a world renowned approach to identifying and remediating mold. After Hurricane Katrina hit New Orleans, Bill wrote and co-produced both a video and a written mold clean up guide that was adopted by the World Health Organization (WHO), and the US Dept. of Housing and Urban Development (HUD). When Hurricane Sandy struck the East Coast, Bill was also brought in to ensure mold and water damage efforts were effective.Although his expertise is in constant demand, Bill stays involved in nearly every Microecologies building inspection and indoor environmental investigation project. Bill is also leading innovation within the health and hygiene industry. He recently developed odor and environmental tobacco smoke (ETS) evaluation criteria that include rigorous quantitative and qualitative elements as well as effective intervention strategies.Even with his extensive scientific background, Bill is known for presenting his findings with clarity and persuasion. It’s why he is regularly asked by individuals, companies, and regulatory agencies to provide expert witness services for both plaintiffs and defendants. Bill has delivered expert testimony in courtrooms across the state from the Supreme Court of New York to the Civil Court of the City of New York. Bill is also a frequent presenter on public health issues and initiatives for institutions such as the American Industrial Hygiene Association.
