Federal environmental officials hope to be done cleaning up chemicals at Knoxville College this week.
The Environmental Protection Agency (EPA) arrived on campus to inspect thousands of bottles left in an abandoned science building earlier this month.
The A.K. Stewart Science Building is one of many vacant buildings at the struggling historic college. The building has been abandoned for several years, but many of the materials used for college-level science classes were never removed.
The agency says there were no special challenges when cleaning up the materials.
Officials are still calculating the total cost of the cleanup, which includes costs to remove and dispose of the materials.
