In August 2023, the University of Pittsburgh School of Public Health and the Pennsylvania Department of Health (DOH) released three “observational epidemiological” studies presenting findings of potential health impacts from human exposure to unconventional natural gas development (UNGD) activities. The studies, which were conducted in eight counties in southwestern Pennsylvania, excluding the City of Pittsburgh, focused on three specific health issues: (1) asthma, (2) birth outcomes, and (3) certain childhood cancers.
In the Asthma Study, researchers reviewed medical treatment for asthma (categorized by severity), as well as how close the patient lived to UNGD activities (considering the number of wells, production volume, and the phase of well development, i.e., preparation, drilling, hydraulic fracturing, and production). The study found no relationship between asthma exacerbations and proximity to wells during the well pad preparation, drilling, or hydraulic fracturing phases, but found an increase during the production phase. The increases were fairly consistent in the lower, moderate, and higher exposure groups and therefore, the expected dose/response relationship (i.e., more asthma exacerbations with more exposure) was not found. See Univ. of Pittsburgh Sch. of Pub. Health, “Hydraulic Fracturing Epidemiology Research Studies: Asthma Outcomes” (July 31, 2023); DOH, “PA Health and Environment Study: Asthma” (Aug. 15, 2023).
For the Birth Outcomes Study, researchers reviewed birth records and the distance mothers lived from UNGD activities and other industrial activities. Researchers for the Birth Outcomes Study considered the number of wells, production volume, and the phase of well development, in addition to potential exposure from certain facilities, i.e., impoundment ponds, facilities accepting oil and gas waste, compressor stations, Superfund sites, and industrial sites with a toxic release inventory. …
