Oil and gas operations produce a variety of pollutants that negatively impact the environment and human health. The most common forms of pollution from these operations are air and water pollution, which can occur at any stage of production or use. Air pollution is caused by the release of methane, a potent greenhouse gas with a global warming potential more than 25 times that of carbon dioxide, and volatile organic compounds (VOCs) that contribute to the formation of ground-level ozone (smog). Water pollution results from oil spills on land via pipeline leaks, accidents, and poor oil storage, contaminating groundwater and surface waters. Other types of pollution include soil pollution, noise pollution, and disruption to wildlife and their habitats.

Oil and gas operations produce air pollution, including methane, VOCs, and air toxics
Oil and gas operations produce a variety of air pollutants, including methane, volatile organic compounds (VOCs), and air toxics.
Methane
Methane is a potent greenhouse gas with a global warming potential more than 25 times that of carbon dioxide. It is emitted during the oil and gas development process, including through flaring, the burning of excess natural gas at oil and gas wells. The oil and natural gas industry is the largest industrial source of methane emissions.
Volatile Organic Compounds (VOCs)
VOCs are a group of chemicals that contribute to the formation of ground-level ozone, also known as smog. Exposure to ozone is linked to a range of health effects, including aggravated asthma, increased emergency room visits and hospital admissions, and premature death. The oil and natural gas industry is the largest industrial source of VOC emissions.
Air Toxics
Air toxics, such as benzene, ethylbenzene, and n-hexane, are emitted during the oil and gas development process. These pollutants are known or suspected of causing cancer and other serious health effects.
The air pollution produced by oil and gas operations can have significant impacts on the health of surrounding communities, particularly those that are disproportionately impacted by pollution, such as Black, Brown, Indigenous, and low-income communities. It can also contribute to climate change, fueling longer wildfire seasons and more dangerous hurricanes.
To combat air pollution from oil and natural gas operations, the US EPA has implemented Clean Air Act regulations that apply to equipment and activities used in the onshore industry. These regulations aim to reduce air pollution and mitigate its harmful effects on public health and the environment.

Oil spills on land can occur through leaks, accidents, and poor storage, contaminating soil and groundwater
Oil and gas operations encompass a diverse range of activities and equipment, including wells, natural gas gathering lines, processing facilities, storage tanks, and transmission and distribution pipelines. While these operations are essential for energy production, they can also contribute to environmental pollution, particularly in the form of oil spills on land.
Oil spills on land can have detrimental effects on the environment and can occur through leaks, accidents, and poor storage practices. Leaks in pipelines or storage tanks can gradually release oil into the surrounding soil, leading to contamination. Accidents, such as ruptured pipelines or overturned storage tanks, can result in sudden and significant oil spills, impacting a large area. Additionally, improper storage of oil, such as using outdated or damaged tanks, can increase the risk of leaks and spills over time.
When oil spills onto land, it can penetrate the soil, contaminating it and rendering it unfit for vegetation and agriculture. The oil can also permeate through the soil and reach the groundwater, causing further pollution. Groundwater contamination poses risks to human health, as it can serve as a source of drinking water for communities. The oil can introduce toxic chemicals and pollutants into the groundwater, making it unsafe for consumption and potentially leading to various health issues.
To mitigate the impacts of oil spills on land, it is crucial to implement preventive measures and response plans. Regular maintenance and inspections of pipelines and storage tanks can help identify and repair potential leaks before they result in spills. Investing in robust storage infrastructure and adopting safe practices can reduce the likelihood of accidents and contain oil spills when they occur. Additionally, developing effective response plans, including rapid containment and cleanup strategies, can minimize the environmental and health impacts of oil spills.
It is important to prioritize sustainable practices and technologies to reduce the environmental footprint of oil and gas operations. This includes adopting advanced spill-prevention measures, implementing strict regulations, and promoting corporate responsibility. By proactively addressing the risks associated with oil spills on land, we can safeguard soil and groundwater resources, protect ecosystems, and ensure the well-being of communities reliant on a clean and healthy environment.

Oil and gas development can disrupt wildlife, nesting, breeding, and migration
Oil and gas operations produce a variety of pollutants, including air, soil, and water pollutants. The industry is a significant source of methane emissions, a potent greenhouse gas with a global warming potential 25 times that of carbon dioxide. It is also the largest industrial emitter of volatile organic compounds (VOCs), which contribute to ground-level ozone (smog) formation. VOC emissions from this industry include air toxics such as benzene, ethylbenzene, and n-hexane, which are suspected carcinogens. Oil and gas wastes can contaminate groundwater and surface waters, and spills can kill vegetation and sterilize soils.
Oil and gas development can have significant negative impacts on wildlife, nesting, breeding, and migration. Loud noises, human movement, and vehicle traffic from drilling operations can disrupt animal communication, breeding, and nesting. Power lines, well pads, fences, and roads can fragment habitats for many species, forcing wildlife into more dangerous areas. For example, the pronghorn antelope and mule deer in Wyoming have been impacted by natural gas field activity during their migration from Grand Teton National Park to the Upper Green River Valley. Oil and gas projects with well pads, fences, pipelines, and roads, as well as constant noise and light pollution, can chop up landscapes, reducing safe spaces for wildlife.
In the Gulf of Mexico, wildlife populations are still struggling more than ten years after the Deepwater Horizon explosion, with millions of birds, dolphins, turtles, and other wildlife killed by the disaster and its lingering impacts. Oil spills and their toxic chemical releases can have devastating effects on local wildlife through direct contact, inhalation, and ingestion. The glare from oil and gas sites, caused by the burning of natural gas, well pads, and storage sites, can disrupt the sleep, feeding, and reproductive cycles of pollinators like bees, affecting plant and fruit reproduction.
The impacts of oil and gas development on wildlife are not limited to physical disruptions but also include population declines. While there are multiple causes for population decline, the role of the industry is undeniable. The U.S. Fish and Wildlife Service declared 21 more species extinct this year, and the World Meteorological Society warned of unprecedented temperatures and extreme weather events globally. Climate change, fueled by emissions from the industry, poses a significant danger to wildlife.
The presence of oil and gas infrastructure on public lands can degrade the experience of visitors expecting to enjoy nature. Hunters, anglers, hikers, and vacationing families encounter oil tanks, power poles, noisy compressors, and busy roads instead of pristine wilderness. The negative impacts of oil and gas development on wildlife and natural landscapes underscore the importance of transitioning to renewable energy sources to preserve the environment and the communities that depend on it.

The process of drilling for oil can disturb land and marine ecosystems
Oil and gas operations produce a variety of pollutants, including air, water, and soil pollution. The process of drilling for oil can disturb both land and marine ecosystems through noise, human movement, vehicle traffic, and oil spills.
The construction of roads, facilities, and drilling sites requires heavy equipment and can destroy large areas of wilderness. This destruction of habitat can be irreversible and can take centuries to recover from. The infrastructure and equipment can also fragment habitats for many species, and the noise and activity can disrupt animal communication, breeding, and nesting.
Oil spills are a major threat to wildlife and can cause long-lasting damage to marine ecosystems. The BP Deepwater Horizon spill in the Gulf of Mexico in 2010 spread oil across 68,000 square miles of the sea surface, killing approximately 1 million seabirds, 5,000 marine mammals, and 1,000 sea turtles. Smaller spills during oil and gas extraction can also be dangerous and have devastating effects on local wildlife through direct contact, inhalation, and ingestion of toxic chemicals.
Drilling produces muds and cuttings that may be discharged near the well site or injected back into the ground, introducing heavy metals and other toxic materials into the marine ecosystem. Seismic surveys and construction activities emit sound that may be harmful to marine mammals, causing them to avoid or move away from their preferred habitat and increasing the risk of ship strikes.
The impacts of oil and gas drilling are felt disproportionately by Black, Brown, Indigenous, and low-income communities, who tend to live in neighborhoods with more pollution. These communities are often located near drilling operations, exposing them to air pollutants such as methane and volatile organic compounds (VOCs), which have been linked to various health effects, including aggravated asthma and increased emergency room visits.
