In the latest installment of their ongoing 18-month investigation, Susanne Rust and Meg Kissinger of the Milwaukee Journal Sentinel found that the U.S. Environmental Protection Agency routinely allows companies to keep new information about their chemicals secret, including compounds that have been shown to cause cancer and respiratory problems.
