Dupont Settles With EPA Over Teflon Chemical

My Way News:

The settlement involves EPA action taken against Dupont for allegedly withholding information about the potential health and environmental risks posed by perfluorooctanoic acid, or PFOA, under provisions of both the Toxic Substances Control Act and the Resource Conservation and Recovery Act.

The EPA alleged that DuPont withheld information for more than 20 years about the health effects of PFOA, also known as C-8, and about the pollution of water supplies near the company's Washington Works plant near Parkersburg, W.Va.

Among other things, the EPA said that DuPont withheld test results indicating that the chemical had been found in at least one pregnant worker from the Washington Works plant and had been passed on to her fetus.

What I want to know is, how did they manage to "withold" the information for 20 years?! Why weren't they subpoenaed? If they were, why did it take so long for action? And they are still under criminal investigation by federal law enforcement! What kind of slackers are running that? Could it be cronies?
