Though the composition of most fracking chemicals remains protected from disclosure through various “trade secret” exemptions under state or federal law, scientists analyzing fracked fluid have identified volatile organic compounds (VOCs) such as benzene, toluene, ethylbenzene and xylene – all of which pose significant
How does fracking affect our water supply?
Fracking can contaminate water supplies if it is not done properly, because the fracking fluid injected into rock to enable gas to be released often contains chemicals. The other possibility of pollution is when the water, which is mixed with chemicals and sand for the fracking process, comes back to the surface.
Can water used for fracking be reused?
Fracking wastewater can contain massive amounts of brine (salts), toxic metals, and radioactivity. And so the gas companies have a problem: what to do with the stuff. Ideally, the water would be reused or recycled, eliminating the need for immediate disposal. And indeed there is a lot of that.
Can fracking contaminate drinking water?
Fracking Can Contaminate Drinking Water. Former EPA scientist Dominic DiGiulio never gave up. The study also suggests that the entire groundwater resource in the Wind River Basin is contaminated with chemicals linked to hydraulic fracturing, or fracking.

What are the environmental impacts of fracking?
Environmental impact of hydraulic fracturing in the United States of shale include the potential contamination of ground water, risks to air quality, the potential migration of gases and hydraulic fracturing chemicals to the surface, the potential mishandling of waste, and the health effects of these, such as cancer.
What is in fracking fluid made of?
The remaining 0.5 percent of the fracking fluid is made up of chemicals. Acids like hydrochloric acid are used in fracking fluids to dissolve the minerals in the rock, soil and sand below the ground. Acid is also used to dissolve parts of the rock to initiate cracking, according to FracFocus.
What is in the chemicals?
A chemical compound can be either atoms bonded together in molecules or crystals in which atoms, molecules or ions form a crystalline lattice. Compounds based primarily on carbon and hydrogen atoms are called organic compounds, and all others are called inorganic compounds.
What are some of the chemicals used in fracking?
Many fracking chemicals are protected from disclosure under trade secret exemptions. Studies of fracking waste have identified formaldehyde, acetic acids, and boric acids, among hundreds of others. For each frack, 80-300 tons of chemicals may be used, selected from a menu of up to 600 *different* chemicals.
What is in the wastewater from fracking?
Fracking wastewater is mostly brines, not human-made fracking fluids. More than 92 percent of the flowback and produced water — or wastewater — coming from the wells is derived from naturally occurring brines that are extracted along with the gas and oil. These brines carry their own risks, Vengosh stressed.
How is fracking fluid disposed of?
Hydraulic fracturing is the process used to stimulate gas production from conventional oil and gas reservoirs. The four most common disposal options are: recycling for additional fracking, treatment and discharge to surface waters, underground injection, and storage in open air pits.

Is water usage an issue in fracking?
Water Use Rises as Fracking Expands. Oil and natural gas fracking, on average, uses more than 28 times the water it did 15 years ago, gulping up to 9.6 million gallons of water per well and putting farming and drinking sources at risk in arid states, especially during drought.
How does fracking natural gas work?
Hydraulic fracturing or fracking creates fractures in the shale formation to release the gas. A fracturing fluid is pumped under high pressure (ca. 100 bar) into the drilling pipe to widen fractures in the rock or to create new ones.
How many gallons of water are used for fracking?
Study: Water Use Skyrockets as Fracking Expands. Oil and natural gas fracking, on average, uses more than 28 times the water it did 15 years ago, gulping up to 9.6 million gallons of water per well and putting farming and drinking sources at risk in arid states, especially during drought.
What does no fracking mean?
Fracking is a slang term for hydraulic fracturing, which is the process of creating fractures in rocks and rock formations by injecting specialized fluid into cracks to force them to open further.
What is involved in the process of fracking?
Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well.
What is the chemical used for?
As previously noted, chemicals perform many functions in a hydraulic fracturing job. Although there are dozens to hundreds of chemicals which could be used as additives, there are a limited number which are routinely used in hydraulic fracturing. The following is a list of the chemicals used most often.
What is in Slickwater?
Slickwater or slick water fracturing is a method or system of hydro-fracturing which involves adding chemicals to water to increase the fluid flow. Fluid can be pumped down the well-bore as fast as 100 bbl/min. to fracture the shale. Without using slickwater the top speed of pumping is around 60 bbl/min.
What does it mean that the fracking chemicals are proprietary?
Hydraulic fracturing or fracking is a means of natural gas extraction employed in deep natural gas well drilling. Once a well is drilled, millions of gallons of water, sand and proprietary chemicals are injected, under high pressure, into a well.
What is the water in fracking used for?
How much water is used during fracking operations? Generally, 2-8 million gallons of water may be used to frack a well. Some wells consume much more. A well may be fracked multiple times, with each frack increasing the chances of chemical leakage into the soil and local water sources.
