Another Battle in the Bushco 'War on Science'

From today's Los Angeles Times:

How Environmentalists Lost the Battle Over TCE

After massive underground plumes of an industrial solvent were discovered in the nation's water supplies, the Environmental Protection Agency mounted a major effort in the 1990s to assess how dangerous the chemical was to human health.

Following four years of study, senior EPA scientists came to an alarming conclusion: The solvent, trichloroethylene, or TCE, was as much as 40 times more likely to cause cancer than the EPA had previously believed.

The preliminary report in 2001 laid the groundwork for tough new standards to limit public exposure to TCE. Instead of triggering any action, however, the assessment set off a high-stakes battle between the EPA and Defense Department, which had more than 1,000 military properties nationwide polluted with TCE.

By 2003, after a prolonged challenge orchestrated by the Pentagon, the EPA lost control of the issue and its TCE assessment was cast aside. As a result, any conclusion about whether millions of Americans were being contaminated by TCE was delayed indefinitely.

The agency's authority and its scientific stature have been eroded under a withering attack on its technical staff by the military and its contractors. Indeed, the Bush administration leadership at the EPA ultimately sided with the military.

After years on the defensive, the Pentagon — with help from NASA and the Energy Department — is taking a far tougher stand in challenging calls for environmental cleanups. It is using its formidable political leverage to demand greater proof that industrial substances cause cancer before ratcheting up costly cleanups at polluted bases.

The military says it is only striving to make smart decisions based on sound science and accuses the EPA of being unduly influenced by left-leaning scientists.

But critics say the defense establishment has manufactured unwarranted scientific doubt, used its powerful role in the executive branch to cause delays and forced a reduction in the margins of protection that traditionally guard public health.

If the EPA's 2001 draft risk assessment was correct, then possibly thousands of the nation's birth defects and cancers every year are due in part to TCE exposure, according to several academic experts.

"It is a World Trade Center in slow motion," said Boston University epidemiologist David Ozonoff, a TCE expert. "You would never notice it."
