Actually, it’s more correct to say they glossed the findings over with a thick coating of shiny stuff.
Air Study Shows No Harmful Levels of Benzene, Other Compounds in Fort Worth and Arlington, District 2

“it is TITAN’s opinion that the elevated formaldehyde concentrations are not being caused by NG Site operations, but instead are being caused by both vehicular traffic and an unidentified source located to the near south/southwest of the NG Site. During the sampling event, TITAN field personnel did not [however] identify any type of emission source that could have caused or contributed to the formaldehyde concentrations”.
The truth, delivered to us Monday in a presentation at the EPA meeting by Houston Advanced Research Center is that formaldehyde levels are more than TWICE the levels in the Houston Ship Channel—2.4 times to be exact.
The US Environmental Protection Agency (EPA) has classified formaldehyde as a probable human carcinogen (cancer-causing substance) under conditions of unusually high or prolonged exposure.
The US National Toxicology program lists formaldehyde as “reasonably anticipated to be a human carcinogen.”
The International Agency for Research on Cancer (IARC), part of the World Health Organization (WHO), has concluded that formaldehyde is a known human carcinogen
North Texas air is worse than the Houston Ship Channel thanks to the Barnett Shale.
Earlier in the year, TCEQ Toxicologist, Shannon Ethridge, compared the levels of benzene in our air to that of the Houston Ship Channel.
However, some of the TCEQ’s testing so far in the Barnett Shale area has shown “some of the highest benzene concentrations we have monitored in the state.” She compared some of the DFW area emissions to those found in the highly industrialized Houston Ship Channel area. LINK
Now we learn that our formaldehyde levels are worse than the Houston Ship Channel.
Here are the numbers:
TCEQ Effects Screening Level (ESL) for HCHO (formaldehyde):
- Acute Short-Term (1 hr): 12 ppb
- Chronic (1 yr): 4.5 ppb (cancer endpoint) This is the important number to me because I live here long-term.
Max 2 hr urban roadside concentrations observed in U.S.
- 17 ppb (HEI, 2007) MAXIMUM from cars
Max 1 hr HCHO in Houston Ship Channel:
- 52 ppb
Barnett Shale levels of formaldehyde:
- 69 ppb
- 81 ppb
- 100 ppb
- 114 ppb
- 127 ppb (2.4 times higher than Houston Ship Channel and 7.5 times higher than maximum roadside levels.)
Following the recommendations in DRILL RIGHT TEXAS: Best oil & gas development practices for Texas would greatly improve these emission problems but industry has shown they will not employ these technologies willingly.
On August 2, The Fort Worth Business Press published an opinion written BSEEC director Ed Ireland.
That is why we chose a licensed engineering firm whose professional engineering stamp on the final report means they are subject to criminal penalties and a loss of their licenses should any information be falsified or inaccurate.
