CHATTANOOGA, Tenn. (AP) - An environmental assessment has found that thousands of spent bullets at a police firing range could be contaminating surface water that drains into the Tennessee River.

A Chattanooga newspaper reports the National Park Service did the assessment to estimate the cost of cleaning up the joint Chattanooga-Hamilton County firing range on Moccasin Bend.

The report found that surface soil on five acres has more than the federal Environmental Protection Agency's acceptable limit for the site, and that contaminated surface water is likely making its way into the river.

City and county officials say they plan to review the findings.

Chattanooga Mayor Andy Berke's spokeswoman Lacie Stone said the administration may also do its own water quality analysis.
