Find fracking wells where you live and what chemicals operators are using

Fracking provides access to fossil fuel reserves locked in underground rock

Using a pressurized fluid mixture that is over 90% water, cracks are created in shale about 2 miles deep to release trapped oil and natural gas. The process uses an average of 3 to 6 million gallons of water per well, which can strain local water supplies.

Many chemicals used in fracking fluid have been classified as toxic

Although the fluid has been known to leach into drinking water supplies, raising health concerns, fracking is exempt from federal clean water regulations due to a loophole in the Energy Policy Act of 2005 championed by former US Vice President Dick Cheney.

Some faucets in regions near fracking wells run flammable water

A 2011 study found methane contamination as much as 3,000 feet away from wells, although there was no evidence of fracking chemicals in tested wells. Water with low methane concentrations is not harmful to drink, but it becomes flammable when mixed with air.

Disposal wells for fracking wastewater have been linked to spikes in seismic activity

A study of all such underground wells in the central and eastern US found that they were 1.5 times more likely to be associated with earthquakes than oil recovery wells. The link between fluid injection and earthquakes was strongest at disposal wells where fluid was injected quickly.

Rising fracking rates have increased prices of some food products

Every fracking well uses approximately 20,000 pounds of guar gum, a thickening and stabilizing agent commonly used in ice cream, salad dressing, and baked goods. The polysaccharide is also a key component in some cosmetics and explosives.

The fracking industry has created hundreds of thousands of jobs since 1949

The method of extracting fossil fuels from shale rock formations has saved Americans an estimated $23B annually in energy costs. Every year, fracking generates billions of gallons of wastewater and causes methane—a greenhouse gas that is over 25 times more potent than carbon dioxide—to leak into the atmosphere.

As of 2024, approximately 44% of Americans support fracking

This makes the method less popular than carbon-free forms of energy production, such as solar, wind, and nuclear power, but more popular than coal mining. Support for fracking increased 7% from 2020 to 2024, primarily due to increased support from Republicans and older Americans.

Fracking originated in the American Civil War

After witnessing how artillery created fissures in narrow water channels, a Civil War veteran wondered if the process could be replicated in underground wells to extract oil. He patented an "exploding torpedo" for this purpose, which became the foundation for future fracking techniques.

A guide to crude oil and natural gas extraction, from rig site preparation to land restoration

Requirements for traffic plans, access roads, and noise barriers vary by state and local laws, but once the rig site is prepared, the rig is assembled and digs a well that is then encased in steel and cement to protect groundwater reservoirs. After drilling and testing the extraction pipe, fracking fluid is injected into the rock to create cracks where crude oil resides, allowing it to be pumped out.

About 10% of the world's crude oil and 32% of its natural gas is reached via fracking

Most of the world's shale oil resources—which are recoverable via fracking—are found in Russia, the US, China, Argentina, and Libya. The majority of equivalent shale gas resources are found in China, Argentina, Algeria, the US, Canada, and Mexico.

Federal subsidies have boosted US fracking profits

Between 2000 and 2020, the US government invested tens of billions of dollars to facilitate the extraction of shale oil and gas reserves. These subsidies helped make new projects viable and kept fossil fuel companies afloat while global energy prices and renewable energy startup costs have fallen.

Most of the 86,000 consumer chemicals registered with the US EPA have never received rigorous toxicity testing, though not all those are still in current use.

Oil and natural gas from fracking is considered unconventional

This method forcibly extracts fossil fuels from tightly packed rocks, where they form from organic matter that has undergone extreme heat and pressure. Conventional drilling, on the other hand, waits for the oil and gas to escape from shale and accumulate in more porous and permeable rocks, such as limestone.

Forever chemicals are so common that experts concluded in 2022 that it's uncertain whether limiting consumer exposure would truly reduce one's exposure to these substances, and noted it would still take years for the body to clear them.

Fracking rates may increase with the construction of new data centers

In Pennsylvania, plans to build at least five new facilities supported by gas-fired power plants are expected to escalate public health risks through surges in air and water pollution. Data center water demands are expected to further strain local resources.

Teflon was an accidental discovery by a DuPont scientist in the 1930s resulting from efforts to create a safe refrigerant.

The value of fracking is dependent on international energy markets

Russia's war in Ukraine spurred calls in the US to increase fracking, which has historically reduced dependence on foreign nations and increased national security. However, some experts argue that renewable energy provides even better energy independence, as fracking investments may not be worthwhile if importing fossil fuels is significantly cheaper.

Fracking technology can help make geothermal power possible almost everywhere

Generating electricity from Earth's thermal energy has previously required existing underground reservoirs of hot water and permeable rocks through which the fluid naturally escapes. Today, fractures can be artificially created to form fluid pathways, and surface water can be injected underground and brought back to the surface.

Fracking has led to an increased global oil supply, contributing to lower oil prices

Fracking technology has significantly increased how much crude oil the US produces. As more countries adopt fracking technology, there could be an increased downward pressure on prices—although fracking has been widely criticized for its negative environmental impacts.

Used since the 1940s, 'forever chemicals' include thousands of different types of substances routinely integrated into industry and consumer products, yet research suggests they can accumulate in the body over time.

Fracking brought short-term wealth and long-term collapse to Rock Springs, Wyoming

In the early 2000s, the fracking boom transformed the quiet mining town into a hub of oil field laborers with plentiful job opportunities. Once the boom faded and industry left, unaffordable housing, unsafe working conditions, and drug epidemics left many residents with no prospects amid a disappearing way of life.

Although PFAS, or forever chemicals, are intentionally designed to be extremely stable and long-lasting because of their strong carbon-fluorine bonds, these bonds can be broken by heat, plasma, and supercritical water.

Understanding why the US can't use its own crude oil and depends on global markets

Before advancements in fracking technology made lighter shale oil readily available, US refineries had been built and optimized for decades to process heavier oil from other countries with high profitability. Despite being able to refine lighter oil, US oil companies can operate with better margins by exporting it to other nations whose refineries are optimized for it and importing heavier oil, for which the US has the infrastructure.

In 2019, the US became a net energy exporter thanks to the fracking boom

The US began exporting more energy than it consumed that year, making it a net energy exporter. Energy imports have decreased every year since 2007, as improved technology has increased the number of accessible domestic oil and natural gas reserves.

Unless prices of fossil fuels rise significantly, their production is expected to slow

US oil and natural gas production skyrocketed from 2000 to 2020, largely due to advances in fracking. However, weak global energy prices have prevented this boom from translating into increased profits for fossil fuel companies.
