Colleyville's will take issue with the methods and analysis, but this study does not replace or refute  theirs, rather it confirms and supplements it.


Colleyville's own final report recommends vapor recovery units and separator pipes based on the vented gases THEY detected during this stage one fracking.  


Our data shows that vented  gases were detectable at levels exceeding TCEQ recommendations 1700 ft away from the pad site.


TCEQ is saying they can't comment on test results from someone else because they don't know what methodology was used. The EPA came up with the methodology that GD Air uses. TCEQ also uses GD Air to analyze their summa canisters. TCEQ often leaves canisters for residents to deploy on their own, just like Colleyville and Southlake residents did. 


The Colleyville consultant has questioned out methodology according to the teaser on Channel 11, but it is the same methodology used by the EPA and TCEQ. 


Another critique is that residents did not call TCEQ. They are so slow to respond residents felt they had to act on their own.


This exposure could have been prevented or reduced if Titan had not violated Colleyville's ordinance and vented gas. 


Southlake's current ordinance requires vapor recovery and prohibits venting.  Some residents in Southlake want to weaken our ordinance.  This case makes me question that logic.  If drilling continues to happen in and around Southlake, 1000 ft setback are not going to be enough to protect you.  We will we need vigorous enforcement and monitoring to ensure our safety.
