About the film
"The largest domestic natural gas drilling boom in history has swept across the
United States. The Halliburton-developed drilling technology of "fracking" or
hydraulic fracturing has unlocked a "Saudia Arabia of natural gas" just beneath
us. But is fracking safe? When filmmaker Josh Fox is asked to lease his land for
drilling, he embarks on a cross-country odyssey uncovering a trail of secrets,
lies and contamination. A recently drilled nearby Pennsylvania town reports that
residents are able to light their drinking water on fire. This is just one of
the many absurd and astonishing revelations of a new country called GASLAND.
Part verite travelogue, part expose, part mystery, part bluegrass banjo
meltdown, part showdown."
Hydraulic Fracturing FAQs
How does hydraulic fracturing work?
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. The pressure fractures the shale and props open fissures that enable
natural gas to flow more freely out of the well.
What is horizontal hydraulic fracturing?
Horizontal hydrofracking is a means of tapping shale deposits containing natural
gas that were previously inaccessible by conventional drilling. Vertical
hydrofracking is used to extend the life of an existing well once its
productivity starts to run out, sort of a last resort. Horizontal fracking
differs in that it uses a mixture of 596 chemicals, many of them proprietary,
and millions of gallons of water per frack. This water then becomes contaminated
and must be cleaned and disposed of.
What is the Halliburton Loophole?
In 2005, the Bush/ Cheney Energy Bill exempted natural gas drilling from the
Safe Drinking Water Act. It exempts companies from disclosing the chemicals used
during hydraulic fracturing. Essentially, the provision took the Environmental
Protection Agency (EPA) off the job. It is now commonly referred to as the
Halliburton Loophole.
What is the Safe Drinking Water Act?
In 1974, the Safe Drinking Water Act (SDWA) was passed by Congress to ensure
clean drinking water free from both natural and man-made contaminates.
What is the FRAC Act?
The FRAC Act (Fracturing Responsibility and Awareness to Chemical Act) is a
House bill intended to repeal the Halliburton Loophole and to require the
natural gas industry to disclose the chemicals they use.
How deep do natural gas wells go?
The average well is up to 8,000 feet deep. The depth of drinking water aquifers
is about 1,000 feet. The problems typically stem from poor cement well casings
that leak natural gas as well as fracking fluid into water wells.
How much water is used during the fracking process?
Generally 1-8 million gallons of water may be used to frack a well. A well may
be fracked up to 18 times.
What fluids are used in the fracking process?
For each frack, 80-300 tons of chemicals may be used. Presently, the natural gas
industry does not have to disclose the chemicals used, but scientists have
identified volatile organic compounds (VOCs) such as benzene, toluene,
ethylbenzene and xylene.
In what form does the natural gas come out of the well?
The gas comes up wet in produced water and has to be separated from the
wastewater on the surface. Only 30-50% of the water is typically recovered from
a well. This wastewater can be highly toxic.
What is done with the wastewater?
Evaporators evaporate off VOCs and condensate tanks steam off VOCs, 24 hours a
day, seven days a week. The wastewater is then trucked to water treatment
facilities.
What is a well's potential to cause air pollution?
As the VOCs are evaporated and come into contact with diesel exhaust from trucks
and generators at the well site, ground level ozone is produced. Ozone plumes
can travel up to 250 miles.
