This is a case of someone pushing forward in the face of established science and nobody should have to pay for this woman's obstinance.

As a hydrogeologist in Alberta, I know that if you find gas in your water well all you have to do is send a sample to the University of Alberta and have them do isotopic analysis of the methane.  Biogenic gas produced by methane producing bacteria below 100 C has a distinct isotopic signature.  Thermal gas is cracked by temperatures above 200 C and also has a distinct isotopic signature.  The origin of the gas is important because the big oil companies are not extracting shallow biogenic gas in aquifer zones, only thermal gas from deep zones.  

If this woman did the proper sampling and tests, they would be conclusive.  All I can assume is that she has the data and it doesn't support her case against Encana or the regulator.  In my experience, there is no way that the regulator would not act on her behalf if she had supporting data.
