Oil Drilling: A Path To Pollution And Environmental Disaster

Oil drilling is a process that involves sinking a pointed power tool into the ground to extract petroleum. While it provides us with the petroleum products we need for fuel, transport, and domestic use, oil drilling has detrimental effects on the environment. From air and water pollution to the disruption of wildlife and their habitats, oil drilling poses significant dangers to our planet. This paragraph will explore the various ways in which oil drilling causes pollution and the subsequent impact on the natural world.

Oil spills

One of the most well-known oil spills in recent history is the Deepwater Horizon spill in the Gulf of Mexico in 2010. The explosion on the drilling platform killed 11 people, and approximately 134 million gallons of oil spilled into the ocean before the well was capped three months later. This spill had far-reaching consequences, including the death of approximately 1 million seabirds, 5,000 marine mammals, and 1,000 sea turtles. It also impacted recreational beaches and shoreline vegetation, with restoration efforts still ongoing more than a decade later.

Another notable example is the Exxon Valdez oil spill in Prince William Sound, Alaska, in 1989. This spill led to the U.S. Congress passing the Oil Pollution Act of 1990, which mandated that all new oil tankers built for use between U.S. ports have a full double hull. This legislation, along with similar international standards established by the International Maritime Organization, significantly reduced the amount of oil spilled from ships during the 1990s.

While large spills like these make headlines, smaller spills during oil extraction and transportation can also have dangerous and deadly effects on local wildlife and ecosystems. These spills often occur due to leaks and splashes of drilling fluids, known as "mud," which are supposed to be captured in lined pits for disposal. A report by the Center for Western Priorities found that 2,179 spills were reported in Colorado, New Mexico, and Wyoming in 2020, highlighting the frequency and impact of smaller spills.

Air pollution

Oil drilling has been identified as a major cause of air pollution, which has significant impacts on the environment and public health. The process of drilling and operating oil wells releases harmful pollutants into the atmosphere, contributing to smog and toxic air quality, and fuelling global warming.

Sources of Air Pollution in Oil Drilling

Oil and gas drilling operations, including oil and natural gas production, natural gas processing, distribution, transmission, and storage, all emit various harmful pollutants. These include toxic particulate matter (PM2.5), carbon monoxide, nitrous oxide, ozone, and volatile organic compounds (VOCs). VOCs, such as benzene and formaldehyde, are known to cause cancer and other adverse health effects.

Impact on Air Quality

The release of these pollutants leads to a decline in air quality, resulting in smog and haze. A study in California found higher levels of air pollutants within 2.5 miles of oil and gas wells, indicating that nearby residents are at risk of exposure to toxic air. This is supported by research from LA County, which found that people living near oil fields have been chronically exposed to higher pollution levels, leading to a vote to phase out oil and gas drilling.

Health Impacts

The health consequences of air pollution from oil drilling are significant. Exposure to pollutants can cause respiratory issues, including asthma and wheezing, and cardiovascular problems. Children are particularly vulnerable, as their developing lungs are more susceptible to the effects of ozone, a powerful oxidant present in the air near wells. Additionally, air pollution has been linked to more severe health outcomes, including preterm birth, heart disease, and even early deaths.

Environmental Impact

The environmental impact of air pollution from oil drilling is also concerning. The emissions contribute to global warming and climate change, with methane being a key contributor. Oil spills, a common occurrence in top-producing states, can also have long-lasting effects on marine ecosystems, killing wildlife and damaging their habitats.

Regulatory Efforts

Recognizing the serious health and environmental risks posed by oil drilling, organizations like WildEarth Guardians and the San Juan Citizens Alliance have pushed for stricter regulations. In 2011, the Environmental Protection Agency (EPA) proposed updating federal air quality standards to control air pollution from oil and gas drilling operations. These efforts aim to reduce harmful emissions, strengthen standards, and safeguard clean air.

Land and marine ecosystem disruption

Oil drilling and extraction can also lead to land degradation and habitat destruction. The construction of roads, pipelines, and other infrastructure can destroy wildlife habitats and disrupt the movement of migratory animals. In addition, the bright lights from drilling sites and complexes can disrupt the sleep, feeding, and reproductive cycles of pollinators like bees, which are crucial for the generation of new fruits and plants.

Marine ecosystems are also vulnerable to the disruptive effects of oil drilling, particularly from offshore drilling operations. Oil spills, whether from blowouts, pipeline leaks, shipping accidents, or drilling operations, can have disastrous consequences for marine life. The BP Deepwater Horizon spill in the Gulf of Mexico in 2010, for example, spread oil across 68,000 square miles of sea surface, killing approximately 1 million seabirds, 5,000 marine mammals, and 1,000 sea turtles. Smaller spills during extraction and drilling, such as those from drilling fluids, can also be harmful and are more common than often reported. These spills can contaminate marine environments, impacting plankton, coral reefs, small fish, crustaceans, and larvae, and leading to long-term health issues and population declines.

The use of sonic and seismic surveys and sound-based technology to locate oil and gas deposits can also have detrimental effects on marine life. These surveys can cause temporary or permanent hearing loss in marine species, impacting their ability to communicate, find food, and navigate. Additionally, the excessive noise generated by oil exploration and drilling activities can cause injury, confusion, and even death among marine species.

Wildlife disruption

Oil drilling has a significant impact on wildlife, causing disruption and damage to habitats and ecosystems. Drilling operations generate noise, human activity, and vehicle traffic, which can disrupt animal communication, breeding patterns, and nesting. The infrastructure associated with drilling, such as power lines, well pads, fences, and roads, can fragment habitats and obstruct migratory pathways. This has been observed in species such as the pronghorn antelope and mule deer in Wyoming, where natural gas field activity has created obstacles for their annual migration.

Oil spills, both large and small, pose a severe threat to wildlife. They contaminate soil, water, and marine ecosystems, leading to devastating explosions and fires and the release of toxic chemicals. The BP Deepwater Horizon spill in the Gulf of Mexico in 2010 resulted in the death of approximately 1 million seabirds, 5,000 marine mammals, and 1,000 sea turtles. Even smaller spills can have detrimental effects on local wildlife through direct contact, inhalation, and ingestion of toxic substances. Drilling fluids, or "mud," can also leak and contaminate drilling sites, causing harm to surrounding wildlife.

The exploration and drilling processes can disturb land and marine ecosystems. Seismic techniques used to explore for oil under the ocean floor can harm fish and marine mammals. On land, drilling often requires clearing vegetation, impacting the habitats of various species. Additionally, the bright glare from oil and gas sites can disrupt the sleep, feeding, and reproductive cycles of pollinators like bees, affecting fruit and plant generation.

The use of hydraulic fracturing, or fracking, in oil production has environmental implications. This technique requires large amounts of water and the use of potentially hazardous chemicals to release oil from rock strata. Drilling also releases heavy metals, toxic particulates, and volatile compounds that pollute the land, air, and water, further endangering wildlife and contributing to climate change.

The impact of oil and gas development on wildlife is undeniable, despite industry claims to the contrary. Wildlife populations are decreasing, and species are going extinct. It is crucial to address these threats and prioritize the protection of wildlife and the environment.

Noise pollution

Noise is a significant issue associated with oil drilling, and it can have a range of negative impacts on both human health and wildlife. Oil drilling operations produce a complex symphony of noise types, including intermittent and continuous sounds of varying intensities. The sources of these noises include truck traffic, well pumps and compressors, drilling and fracturing, and flaring and venting. The expansion of oil infrastructure, including compressor stations, processing plants, and pipeline facilities, has exacerbated the problem, as these facilities can be in operation day and night for extended periods, affecting nearby residents.

The noise levels from oil drilling activities often exceed the maximum permissible limits for residential and commercial zones, which are typically 55 dBA and 60 dBA, respectively. For example, researchers in Colorado found noise levels at oil and gas sites ranging from 50-70 dBA, and in some cases, exceeding 80 dBA. Similarly, studies in West Virginia measured noise levels around oil and gas operations, frequently above 55 dBA and reaching up to 87 dBA in certain locations.

The impact of this noise pollution on human health can be significant. High-decibel noises can cause hearing loss, sleep disturbances, irritability, cardiovascular issues, and stress-related conditions. Even low-level sustained noises can disturb sleep and concentration and contribute to stress and mental health issues. The fluctuations in noise levels and the constant background rumble from compressor stations can be particularly challenging for residents to adjust to, affecting their quality of life.

To address these concerns, various noise reduction techniques and technologies have been proposed. These include the use of temporary or portable noise screens, noise barriers, and sound walls. Additionally, natural noise barriers, such as hills and trees, can be incorporated into location siting decisions to mitigate the impact on nearby communities.
