The Pentagon says it found contamination from a toxic chemical, perchlorate, at 14 abandoned or scheduled to be closed military bases nationwide. But a Democratic senator said Friday more facilities should have been examined.
In the report sent to lawmakers, the Pentagon said it found the chemical in ground water and soil samples at closed sites in 10 states.
Perchlorate, a toxic chemical from rocket fuel and weapons production, has been linked to thyroid damage.
The amounts found ranged from 1.2 parts per billion in ground water at Fort McClellan in Alabama, to as high as 2,890 parts per billion in some samples of ground water at Fort Wingate Depot in New Mexico.
There is debate about what constitutes dangerous levels of perchlorate, but the Environmental Protection Agency's draft proposal for drinking water is one part per billion. Some but not all drinking water supplies draw on ground water.
Perchlorate has been found in drinking water supplies in 29 states and has also been found in vegetables.
The eight-page report, issued in response to a congressional mandate, was more than two months overdue. Sen. Dianne Feinstein, D-Calif., released a letter to Defense Secretary Donald Rumsfeld Friday saying it didn't meet congressional demands.
Feinstein said the report should have addressed 74 potentially contaminated closed bases - a number contained in a General Accounting Office report from 2003.
She also complained that the Pentagon shouldn't wait for the EPA to issue a final national standard for perchlorate to develop clean-up plans. The final standard isn't expected until 2006 and the report indicates clean-up at most bases will wait until then.
