This document analyzes whether low-income counties are more likely than higher-income counties to host fracking sites if located above shale gas formations. The author finds counties' median income levels do not correlate with the presence of fracking wells in Texas, Colorado, Oklahoma and Pennsylvania. Possible reasons are that fracking occurs on large, open plots of land regardless of the county's income level. The author suggests future studies examine economic effects within counties before and after installing fracking wells.
4. Are low income counties more prone to
become fracking locations if they are located
above a shale formation containing natural
gas, above all other income level counties?

18. Does not match with hypothesis!
Possible instances why this would be:
▪ Fracking usually occurs on large areas of open/available
land (e.g. ranches, farms).
For Future Study:
Study the effects of fracking wells within counties
by looking at economies before and after.
Editor's Notes
Fracking or hydraulic fracturing is the process of extracting natural gas from the shale under the ground and has been known to cause much environmental damage.
Hydraulic fracturing or fracking is used to help oil and gas companies access the supplies of natural gas held deep into the ground. A fracking pad can range from 5-15 acres. Each well may be fracked up to eighteen times during its productive life. This process involves drilling 5,000 – 8,000 feet below the surface and a comparable distance horizontally. Millions of gallons of water, sand, and proprietary chemicals are injected, under high pressure, into the well. The pressure fractures the shale and creates fissures that enable natural gas to flow more freely out of the well. These fissures allow the chemicals to enter the groundwater system. The gas bubbles to the surface needing to be separated from the contaminated wastewater, however only 30-50% of the water is typically recovered from the well. This fracking fluid is left in the ground as well as on the surface. Only 30 - 70% of the chemicals come up as well while the rest remains in the soil and in the groundwater.
