·
Hydraulic fracturing, or “fracking”, is the
process of drilling and injecting fluid into the ground at a high pressure in
order to fracture shale rocks to release natural gas inside.
·
Each gas well requires an average of 400 tanker
trucks to carry water and supplies to and from the site.
·
It takes 1-8 million gallons of water to
complete each fracturing job.
·
The water brought in is mixed with sand and
chemicals to create fracking fluid. Approximately 40,000 gallons of chemicals
are used per fracturing.
·
Up to 600 chemicals are used in fracking fluid,
including known carcinogens and toxins such as…LEAD, URANIUM, MERCURY, ETHYLENE
GLYCOL, RADIUM, METHANOL, HYDROCHLORIC ACID, and FORMALDEHYDE.
·
The fracking fluid is then pressure injected
into the ground through a drilled pipeline.
·
500,000 Active gas wells in the US X 8 million Gallons
of water per fracking X 18 Times a well can be fracked.
·
The mixture reaches the end of the well where
the high pressure causes the nearby shale rock to crack, creating fissures
where natural gas flows into the well.
·
During this process, methane gas and toxic
chemicals leach out from the system and contaminate nearby groundwater.
·
Methane concentrations are 17x higher in
drinking-water wells near fracturing sites than in normal wells.
·
Contaminated well water is used for drinking
water for nearby cities and towns.
·
There have been over 1,000 documented cases of
water contamination next to areas of gas drilling as well as cases of sensory,
respiratory, and neurological damage due to ingested contaminated water.
·
Only 30-50% of the fracturing fluid is
recovered, the rest of the toxic fluid is left in the ground and is not
biodegradable.
·
The waste fluid is left in open air pits to
evaporate, releasing harmful VOC’s (volatile organic compounds) into the
atmosphere, creating contaminated air, acid rain, and ground level ozone.
·
In the end, hydraulic fracking produces
approximately 300,000 barrels of natural gas a day, but at the price of
numerous environmental, safety, and health hazards.
