EPA unaware of industry ties on cancer review panel

By David Heath and Ronnie Greene

In September 2010, scientists at the Environmental Protection Agency came to a startling conclusion: Even a small amount of a chemical compound commonly found in tap water may cause cancer.

The compound, hexavalent chromium, gained infamy in the Oscar-winning film Erin Brockovich, based on the David-vs.-Goliath legal duel between desert dwellers in Hinkley, Calif., and Pacific Gas & Electric Co. The film ends in Hollywood fashion, with the corporate polluter paying $333 million to people suffering from illnesses.

But in real life, the drama continues. More than 70 million Americans drink traces of chromium every day, according to the Environmental Working Group, a nonprofit research organization.

And now, more than a decade after the film, EPA scientists cite "clear evidence" that the chemical compound, also known as chromium (VI), can cause cancer. The federal agency was poised to announce its findings in 2011, a step almost certain to trigger stricter drinking-water standards to prevent new cancers and deaths.

The chemical industry's trade association and chief lobbyist, the American Chemistry Council, urged the EPA to wait for more research, a common practice to delay action on toxic chemicals. However, Vincent Cogliano, the soft-spoken head of EPA's chemical-assessment program, rebuffed the powerful group, writing in an April 2011 letter that "strong" new research was already available.

Ten months later, the EPA reversed itself, quietly posting a notice on the Internet that it was pushing back the release of its findings for at least four more years. Environmentalists were stunned at the reason: The agency would wait for the results of new studies costing $4 million and paid for by the American Chemistry Council.

The EPA decided to wait at the urging of a panel of scientists chosen to give an unbiased review of the chromium findings. But the EPA doesn't vet these scientists directly, instead handing the task over to outside contractors. An investigation by the Center for Public Integrity found that several of the panelists had worked on behalf of PG&E to defend the company in the Brockovich lawsuits.
