TRAVERSE CITY, Mich. (AP) -- Federal officials say they're still working on a report that describes potential health risks near the Great Lakes region's most heavily polluted sites.
The U.S. Centers for Disease Control and Prevention was expected to release the report last summer. But a spokesman says in-house reviewers found problems that are being fixed.
Some scientists and members of Congress have criticized the CDC for withholding the report. They say that despite its flaws, the document could give communities valuable information about local health threats that need further study.
The roughly 400-page document uses statistics from government databases to assess risks for people living near 26 polluted sites in the Great Lakes region. Some of the locations have abnormally high cancer rates.
