ENVIRONMENTAL IMPACTS OF GAS DRILLING 101

Water Well Contamination

Cornell University Cooperative Extension offers the following documents pertaining to water well contamination resulting from natural gas development. All instances of contamination that we have found thus far have not been caused by hydro-fracturing chemicals, but have been instead caused by improper well casings that have resulted in methane migration into aquifers or the turbidity that results from methane migration or ground vibrations.

SPLASHDOWN Editorial: Contrary to the above claim that all instances of contamination have not been caused by hydro-fracturing chemicals, real proof exists:

  1. Why not check the air quality level of an area through the different websites that are providing information on a regular basis about the asthma and allergy allerts as well as air quality level of the area one is residing. One such weblink I use is http://aafter.com/?term=w? This will help residents to take appropriate measures against such diseases like asthma and other respiratory diseases.
