Hydraulic fracturing or “fracking”
has been associated with water contamination, global warming-causing air
pollution, health problems, falling property values and
even earthquakes. Each year fracking pumps billions of gallons of water
and chemicals deep underground under high pressure to force open
cracks and release natural gas.
According to the House
Energy and Commerce Committee, the chemicals used in fracking fluids
include over 750 different chemicals. Some are innocuouse (salt, gelatin)
while others pose significant human health hazards (methanol, isopropanol
and 2-butoxyethanol). About 650 of the 750 chemicals used in fracking
operations are known carcinogens, according to the report filed with the
U.S. House of Representatives in April 2011. They include toxic chemicals
like benzene and tholuene.
Natural gas has garnered a lot of
attention, but the research reveals it is anything but clean. To
increase domestic energy production and reduce reliance on coal, there is a
natural gas boom in the U.S. and
elsewhere. However, reliance on natural gas is not a panacea to our
energy woes. According to a February
2012 study published in Nature, extracting and
producing natural gas releases enough methane into the atmosphere to
negate any greenhouse gas advantages that its somewhat cleaner burning
chemistry provides.
