Confronted by reporter Mark Greenblatt, TCEQ staffer Linda Brookins  claimed that the radiation was "natural" and people shouldn't be  concerned. She also refused to read on camera the EPA's order to stop  subtracting margins of error from radiation test results.
KHOU called it "Texas math," in part two of its ongoing series.
Thanks to the TCEQ's under-reporting of radioactive content, one particular water provider in Harris County was able to skirt needed maintenance for years, even though uncensored tests showed radiation was almost always above legal limits.
Independent tests, the station noted, showed that some of the radiation contained harmful alpha particles, which can cause cell mutations and increase the risk of cancer.
The practice of under-reporting radiation continued until last year, when the EPA once again demanded Texas comply with the law.
"What was illegal and a bad idea yesterday is illegal and a bad idea  today," TCEQ chairman Bryan W. Shaw told  The Dallas Morning News. "We won't see any environmental  benefits from this. We'll just see the additional bureaucracy associated  with permitting in this state and across the U.S."
