Impacts of FrackingJanuary 14, 2013
Expert: Roxana Zulauf Witter, M.D.
The practice of hydraulic fracturing (fracking) to extract natural gas has expanded in recent years. The practice has fueled a national debate about the shale gas extraction process. Some people think that this practice will help provide for energy security. Others are concerned about the environment. Increasingly there are people who are worried about how fracking might affect their health and safety. In this podcast, we talk about the science of fracking, what we do—and don’t—know about its impacts, and how Health Impact Assessments could be used as an approach to identify how drilling might affect community members.
Roxana Zulauf Witter, M.D., is an assistant research professor in the Department of Environmental and Occupational Health in the Colorado School of Public Health (CSPH). Dr. Witter’s research on identifying and mitigating the potential health effects of natural gas development focuses on the impacts of chemical emissions on physical health as well as the impacts of community change on psychosocial health. She is the principal investigator for the Health Impact Assessment for natural gas drilling in Battlement Mesa, Colorado. She is also program director for the Occupational and Environmental Medicine Residency and co-director of the Environmental and Occupational Interdisciplinary Symposium in CSPH. She completed her B.S. at Georgetown University and earned an M.S. degree in microbiology and immunology, an M.D. degree, an M.S.P.H., degree and completed a residency in occupational and environmental medicine at the University of Colorado School of Medicine. She has also spent several years in private clinical occupational and environmental medicine practice and working as medical director for a Denver-based international corporation.
