THE PROCESS
MARCELLUS SHALE
THE ATTACK ON FRACK
http://www.cleanwateraction.org/page/fracking-process
1) A well is drilled vertically to the desired
depth, then turns ninety degrees and
continues horizontally for several thousand feet into the shale believed to contain the trapped natural gas.
2) A mix of water, sand, and various chemicals is pumped into the well at high pressure in order to create fissures in the shale through which the gas can escape.
3) Natural gas escapes through the fissures
and is drawn back up the well to the surface, where it is processed, refined, and shipped to market.
4) Wastewater (also called "flowback water" or "produced water") returns to the surface after the fracking process is completed.
ENVIRONMENTAL DRAWBACKS FROM DRILLING
THE TRUTH
Injects a mixture of water, sand, and chemicals to crack dense rock formations and release its natural gas
New techniques, technologies, and chemicals are more intensive and riskier than conventional gas drilling
The fracking mixture includes acids, detergents, and poisons not regulated by federal laws
Gas industry claims toxic chemicals are only 1% of the hydrofrack fluid but on average a 3 million gallon hydrofrack will produce 15,000 gallons of chemical waste

Water Consumption
3 to 8 million gallons of water per hydrofrack
Air Pollution
Methane leaks rampantly throughout the extraction, processing, and distribution of oil and gas
Contaminated Surface Water
Water from gas wells can contain low concentrations of radioactive elements and huge concentrations of salt when returning to the surface
Deforestation
The drilling site displaces the species living in the area because of habitat destruction

Water Contamination
The millions of gallons of water used in fracking operations not only strain water resources, but end up as vast amounts of contaminated wastewater
Methane found in tap water linked to fracking
Chemicals from drilling
Exposure to toxic chemicals even at low levels can cause tremendous harm to humans; the endocrine system is sensitive to chemical exposures measuring in parts-per-billions, or less
Oil and gas production have been linked to increased risk of cancer and birth defects in neighboring areas; as well as to a risk of increased seismic activity
Noise Pollution
Decreased property value due to noise from loud, twenty-four hour hydrofracking operations

PROPOSAL: WE PROPOSE THAT THE MARCELLUS SHALE SHOULD NOT BE OPENED IN UPSTATE NEW YORK
http://www.propublica.org/article/scientific-study-links-flammable-drinking-water-to-fracking
The Marcellus Shale extends 90,000 square miles deep underground from Ohio and West Virginia northeast into Pennsylvania and southern New York
The Catskill and Delaware watersheds provide over 90 percent of New York City’s drinking water supply
The Department of Environmental Protection has spent more than $1.5 billion to protect this watershed
Natural gas development produces a level of industrial activity and heightened risk of water quality contamination

“This unconventional gas extraction technique presents environmental risks, despite economic or energy security benefits, including: air, soil, and water contamination; water usage competition; ecosystem damage; habitat and biodiversity impacts; and fugitive gas emissions.” - United Nations Environment Program
