Dr. Kerry Hamilton is an Assistant Professor with a joint appointment in the School for Sustainable Engineering and the Built Environment and the Biodesign Institute Center for Environmental Health Engineering at Arizona State University. She received her doctoral degree in Environmental Engineering from Drexel University in 2016 and Master of Health Science (MHS) degree in Environmental and Occupational Hygiene from Johns Hopkins University in 2009. She was a Fulbright Scholar to Australia in 2015 and Public Health Fellow at the US Environmental Protection Agency from 2009-2011. Her research interests are in the areas of environmental microbiology, water quality, risk assessment, and decision analysis.
Legionella spp. is a key contributor to the United States waterborne disease burden. Despite potentially widespread exposure, human disease is relatively uncommon, except under circumstances where pathogen concentrations are high, host immunity is low, or exposures to small-diameter aerosols occurs. Water quality guidance values for Legionella are available for building managers but are generally not based on technical criteria. To address this gap, a quantitative microbial risk assessment (QMRA) was conducted using target risk values in order to calculate corresponding critical concentrations on a perfixture and aggregate (multiple fixture exposure) basis. As a result, single sample and average concentration guidance values are proposed to inform water safety plans that are protective of public health.
