Fracking and Health: Ask an Expert

The plastic lifecycle starts with oil and gas extraction and extends through manufacturing, consumer use, and waste management. David Azoulay, Director of the Environmental Health Program at the Center for International Environmental Law (CIEL) and coauthor of “Plastic & Health: The Hidden Costs of a Plastic Planet” report, details potential exposures and health impacts at each stage of the plastic lifecycle. He suggests that organizations collaborate to create one compelling narrative addressing the entire lifecycle, working together to find solutions to plastic’s toxic legacy.

Ethane, a byproduct of natural gas extraction, is used in ethylene production, the primary feedstock for plastic manufacturing. Steven Feit, an attorney in the Climate and Energy Program of the Center for International Environmental Law (CIEL) and coauthor on their “Fueling Plastics” investigative series, explains how the U.S. fracking boom is now targeting ethane as a separate commodity, leading to an expansion of infrastructure along the fossil fuel to plastics supply chain. He encourages a collaboration among organizations to include the entire plastic lifecycle when addressing health and environmental impacts.

Millions of barrels of flowback and produced water, laden with toxic chemicals, come to the surface during oil and gas production. Dr. Isabelle Cozzarelli, Research Hydrologist in the USGS National Research Program, describes the wastewater cycle from fracking to disposal including risks to human and environmental health, and invites nonprofit organizations to contribute to discussions on current wastewater issues.

The United States has over three million miles of pipelines used for gathering, transporting, and distributing natural gas and liquids, including crude oil. Carl Weimer, Executive Director of the Pipeline Safety Trust, provides details on who is in charge of pipeline safety and what happens when pipelines fail. He addresses potential health and environmental impacts, and how current regulations are not sufficient to protect public health and safety.

Volatile organic compounds (VOCs) are released along with methane during oil and gas operations and contribute to local and regional ozone formation. Lesley Fleischman, Senior Analyst with Clean Air Task Force, explains how venting and leaking VOCs can impact lung health and respiratory function. She encourages NGOs to educate themselves and push for tighter methane and VOC regulations at the state and federal levels. Note: an earlier version of this podcast incorrectly put the number of facilities at 12 million. The current podcast has the correct number at 1.3 million.

Biocides may be released into the environment in produced water through spills, surface water disposal, or reuse, potentially impacting public health and the environment. Dr. Thomas Borch, Professor in the Department of Soil and Crop Sciences at Colorado State University, discusses why biocides are used in fracking and describes the difficulties identifying and measuring them in produced water.

As unconventional oil and gas extraction evolves, the scale of operations expands to include more wells, more chemicals, more sand, more emissions, more waste. Dr. Tony Ingraffea, Professor of Engineering, Emeritus, at Cornell University, explains how this increase in scale leads to higher risk of environmental pollution and potential health impacts. He suggests starting with the facts to effectively educate stakeholders and decision makers.

The uncertainty surrounding environmental and public health impacts of fracking can lead to individual and community stress. Dr. Stephanie Malin, Associate Professor in the Department of Sociology at Colorado State University, discusses social stressors such as diminished quality of life, feelings of uncertainty and powerlessness, and community tension and offers insight into how communities can address these challenges.

“Beneficial reuse” of produced water, a byproduct of oil and gas development, includes road spreading for dust suppression and deicing. Dr. William Burgos, Professor in the Department of Civil and Environmental Engineering at Penn State University, describes beneficial reuse of produced water focusing on dust suppression for roads. He addresses chemical contaminants, exposure pathways, and potential impacts on human and ecological health and includes suggestions to strengthen protections when reusing wastewater.

As fracking operations move closer to populated areas, communities are concerned about potential impacts on their health and safety. Dr. Gregory Howard, environmental public health scientist and consultant, describes various health study designs with a focus on the goals and needs of the community and the decision makers they are trying to reach as well as the challenges of doing such research.
