  2. WHAT IS HYDROFRACKING?

  3. Hydrofracking, or Hydraulic Fracturing, is a process of extracting natural gas from underlying shale rock. • Wells are drilled into the ground, first a vertical well then a horizontal well, going deep below the surface under these shale rock formations. • Using highly pressurized “fracking fluid”, it creates afissurein the rock by which natural gas can escape to the surface.

  4. WHAT IS FRACKING FLUID? • An average fracking well uses 4.5-5 MILLION GALLONS of water An average swimming pool contains 16,000 gallons of water so a typical well uses 282-312 average size swimming pools of fresh water!!! • Then a mixture of sand and chemicals are added to that water.. • To be fair, fracking fluids composition of chemicals totals < 1% of the overall mixture. • Still, these chemicals include benzene, toluene, ethylbenzene, xylene, and a combination of nitrogen oxides. • Contact with these chemicals can lead to several health problems such as skin, eye, and sensory organ problems, respiratory problems, gastrointestinal or liver problems, brain and nervous system problems, and cardiovascular health problems.

  5. HOW BAD IS IT? • Thousands of Chemicals can get into our water supply (and already have in some areas) • Thousands of gallons of water can deplete rivers and streams and can affect our water supply • The chemically composed water known as “fracking fluid” has to go somewhere, and we don’t have the capability to deal with the large amounts of chemicals, so they’ve been ending up in rivers, streams, and in the ground, leaking into the groundwater!!!

  6. WHERE ARE THEY GETTING ALL OF THIS WATER FROM TO OPERATE THESE WELLS?

  7. As of 2009, several rivers in Pennsylvania were already extensively pumped from Natural Gas companies. • Sugarcamp Run and Cross Creek are two rivers in western Pennsylvania where companies did not have any regulation on stream water usethat fell victim of the huge amount of water needed to drill. • Essentially water trucks could go to the nearest stream and pump all the water they want.

  8. Hydrofracking Sites • Drilling has already been going on in the Western United States. • Projects have commenced in, targeting the Marcellus Shale Formationthat underlies Pennsylvania, West Virginia, Ohio, and Southern New York

  9. How did the Marcellus Shale form? • About 385 million years ago, what is now western Pennsylvania was part of a large inland sea. Organisms died and dropped to this sea floor over time and mixed with sediments brought into the sea by rivers from the surrounding landmass. Over millions of years, as the continents moved and tectonic plates collided, mountains were formed, rivers were redirected, and the biological and inorganic sediments were buried under additional layers of rock, compressing them further. The extreme pressure and heat at greater depths converted the organic material into hydrocarbons, including those that make up natural gas. These hydrocarbons are not contained in reservoirs like oil, but rather are distributed throughout the shale in very thin layers and pores. This is why the rock must be fractured for the gas to escape.

  10. The Marcellus Shale lies underneath about 90,000 square miles of Pennsylvania, Ohio, New York, and West Virginia. It lies at varying depths from the surface to 9,000 feet and is believed to hold 500 hundred trillion cubic feet of natural gas. Between January and June of 2011, Marcellus wells produced 432.5 billion cubic feet of natural gas.

  11. Where does the water end up?

  12. Anywhere from 30-70% of spent Fracking Fluiddoes not resurface during the drilling process!

  13. The close proximity to big cities.. • Marcellus Shale Formation underlies the Delaware River Basin area that supplies water to roughly 16 million people, including those in New York City, Philadelphia, and Pittsburgh

  14. OUR PRECIOUS SOURCE OF FRESH WATER IS FACING MAJOR THREATS!!!

  15. The Halliburton Loophole • In 2005, the Bush/Cheney Energy Bill exempted natural gas drilling from the Safe Drinking Water Act. Itallows companies to disclose information in regards to the chemicals used during hydraulic fracturing. Essentially, the provision took the EPA off the job. It is now commonly referred to as the“Halliburton Loophole” • WHY WOULD THEY MAKE SUCH A RIDICULOUS EXEMPTION LIKE THIS?

  16. Do you trust Dick Cheney?

  17. stock options had risen 3,281% between 2004-2005. Cheney owned over 400,000 shares of the companies stock at that time.

  18. The Fact of the Matter... • This energy rich shale has been there for millions of years, until we extensively research and develop techniques that are 100% safe and do not threaten our water supply we can leave it alone. • The fact that there are already communities in existence out there suffering from the negative consequences of the extraction of natural gas is all the evidence I need to support my sentiment for fracking. Renewable energy is the way to go! • The Sun provides us with 20,000 times more energy than our global consumption. • Today, the technology produces less than one tenth of one percent of global energy demand.
