Dr. David Krause, the national practice leader for building health sciences at Geosyntec Consultants, holds a Doctorate in Environmental and Occu- pational Health and Masters of Science in Public Health from the University of South Florida. He has 20 years of experience in environmental science and public health, focusing in the areas of toxicol- ogy, occupational health, industrial hygiene, indoor air quality, and chemical emission testing. Prior to joining Geosyntec, Dr. Krause served as the State Toxicologist for the Florida Department of Health and led efforts to investigate potential public health risks associated with corrosive Chinese drywall and the Deepwater Horizon Oil Spill. He co-authored the 2009 Florida DOH Guidelines for the Surveil- lance, Investigation, and Control of Legionnaires' Disease in Florida. David is a Certified Industrial Hygienist with expertise in combustion products, flame retardants, irritant chemical exposures, indoor air quality, Legionnaires disease, and mold. blind luck when directing prevention, testing, and remediation activities. Most cases recorded in the national surveil- lance system (~95%) are not associated with an outbreak, meaning most cases are never fully investigated. Because of the absence of regula- tory requirements almost all recommendations for proactive control of Legionella in building water systems comes in the form of voluntary guidance, even from OSHA. Currently pub- lished voluntary guidance documents have not been adopted or incorporated by reference to local, state, or federal codes or regulations. This is not an argument for the blanket adop- tion of current guidelines into regulation, but we should recognize the limitations of currently available voluntary guidance and regulatory requirements in protecting the public from LD. The next article in this four part series will ex- amine the multiple factors contributing to the in- creasing incidence rate of Legionnaires' disease and a predicted increase in the coming years. Failing infrastructures, decreased regulatory enforcement, and regulatory requirements that conflict with prevention of Legionella amplifica- tion in plumbing systems are among the many issues that will be scrutinized. 1.
