On Thursday, August 20th, ABCAlliance members provided three investigators an executive summary, a timeline and additional documents to support documentation provided by TCEQ state investigators stating that 1,2 dibromoethane, also called EDB, a known carcinogen which ranks as the top carcinogenic substance on the Human Exposure/Rodent Potency Index, was present in at least six air samples found in Argyle and Bartonville. Four of those cases were at concentrations exceeding the state’s long-term threshold of .05 parts-per-billion:
- 12/6/2010 Trios; 0.01 ppb
- 4/11/2011 at Gulftex Frenchtown; 0.12 ppb
- 5/13/2011 at Gulftex Frenchtown; 0.08 ppb (1st sample)
- 5/13/2011 at Gulftex Frenchtown; 0.08 ppb (2nd sample)
- 5/19/2011 at Argyle Central; 0.11 ppb
- 5/30/2011 at Argyle Central; 0.02 ppb
On two occasions, TCEQ State Investigators told an Alliance member the source of the EDB found was not related to gas or oil, but is historical soil contamination. A written report was also provided. State Investigators did not provide evidence to support either of these assertions.
Five ABCAlliance members have not only provided baseline Summa samples of the air, but also soil and water samples to the EPA. Air samples taken in the spring of 2010 near Argyle Central and Gulftex found no instances of EDB. A water sample from White’s Branch, just upstream of Argyle Central, in March 2010 found no EDB. Three soil samples in March 2010 near Argyle Central also found no EDB. Additional soil samples in April 2010 near Gulftex found no EDB. (click to enlarge)
Historic contamination of EDB as documented on the Agency for Toxic Substances & Disease Registry shows no contamination in Texas. In addition, our preliminary review of contaminated sites elsewhere in the United States shows that where there is air contamination there is also significant soil and water contamination.
On December 10 2010, at a Bartonville Town Council Meeting, a representative of Gulftex admits to the town of previously using a biocide that is on the EPA e-docket list for being banned in commercial use. She also claimed she was a chemist. EDIT: You can listen to the audio from that town meeting here.
The ABCAlliance members are deeply troubled by the fact that EDB is present in quantities above the long-term appropriate comparison monitoring values set by TCEQ, yet the agency is refusing to investigate because they say it is historical soil contamination, but they refuse to provide evidence to support this.
The Alliance would like an immediate investigation done by the EPA to determine the source of the EDB and provide for its elimination. It seems like a reasonable request, but now TCEQ state investigators are denying that their scientific testing techniques were ever scientific and it is possible that the detected carcinogen was never detected at all. One mistake in testing we could understand, or maybe even two mistakes in detection. But this carcinogen was detected SIX TIMES.
And to put the cherry on top, according the Denton Record Chronicle article, the EPA is saying they will support the TCEQs decision of unscientific detection, but will continue to monitor the area.
Wham bam thank you ma’am.
Do you see our frustrations here?
Gas related or not, all we are asking for is clean air, water and soil for our community. If your child was breathing a carcinogen wouldn’t you want and demand that source to be cleaned up? And yet, our state and federal investigators are failing us. Who do we turn to before more people in our community die of cancers or other diseases?
