PHILADELPHIA — Groundwater and air quality testing before, during, and after natural gas drilling – which includes hydraulic fracturing -- should be key components of efforts to ensure the safety of communities near these sites, according to an expert panel convened to weigh in on public health research needs associated with unconventional natural gas drilling operations (UNGDO). The panel also urges that any research conducted should use “community-based participatory research principles” so that the concerns of the many stakeholders involved in these activities can be addressed.
A group of environmental health researchers, led by Trevor Penning, PhD, director of the Center of Excellence in Environmental Toxicology (CEET) at the Perelman School of Medicine, University of Pennsylvania, published their findings this month in Environmental Health Perspectives.
UNGDO, which includes hydraulic fracturing and horizontal drilling, supplies an energy source which is potentially cleaner than liquid or solid fossil fuels and may provide a route to energy independence for the U.S, say proponents. However, significant concerns have arisen due to the lack of research on the public health impact of this type of energy extraction.
“The working group was convened following presentations on the potential of natural gas drilling to adversely affect public health at the 2012 Annual Environmental Health Sciences Core Centers [EHSCC] meeting at Harvard School of Public Health,” states Penning.
Sixteen of the twenty EHSCCs funded by the National Institute of Environmental Health Sciences (NIEHS) joined the working group to review the literature on the potential public health impact of UNGDO and to make recommendations for research.
The Inter-EHSCC Working Group concluded that a potential for water and air pollution exists that might endanger public health and that the social fabric of communities could be affected by the rapid emergence of drilling operations. The working group recommends research to inform how potential risks could be mitigated.

Penn Medicine is one of the world's leading academic medical centers, dedicated to the related missions of medical education, biomedical research, and excellence in patient care. Penn Medicine consists of the Raymond and Ruth Perelman School of Medicine at the University of Pennsylvania (founded in 1765 as the nation's first medical school) and the University of Pennsylvania Health System, which together form a $4.9 billion enterprise.
The Perelman School of Medicine has been ranked among the top five medical schools in the United States for the past 17 years, according to U.S. News & World Report's survey of research-oriented medical schools. The School is consistently among the nation's top recipients of funding from the National Institutes of Health, with $409 million awarded in the 2014 fiscal year.
The University of Pennsylvania Health System's patient care facilities include: The Hospital of the University of Pennsylvania and Penn Presbyterian Medical Center -- which are recognized as one of the nation's top "Honor Roll" hospitals by U.S. News & World Report -- Chester County Hospital; Lancaster General Health; Penn Wissahickon Hospice; and Pennsylvania Hospital -- the nation's first hospital, founded in 1751. Additional affiliated inpatient care facilities and services throughout the Philadelphia region include Chestnut Hill Hospital and Good Shepherd Penn Partners, a partnership between Good Shepherd Rehabilitation Network and Penn Medicine.
Penn Medicine is committed to improving lives and health through a variety of community-based programs and activities. In fiscal year 2014, Penn Medicine provided $771 million to benefit our community.
