GREENVILLE, S.C. (AP) -- The trustees of an environmental settlement fund have agreed to study PCB contamination in a South Carolina river as they consider the removal of a dam.

The Greenville News reported Wednesday the trustees of the $9 million fund for Twelve Mile River have agreed to spend $225,000 to study contamination in the stream behind a third dam on the stream.

U.S. District Judge G. Ross Anderson last October recommended that $3 million be spent to remove the dam to reduce the effects of PCB contamination in the river and Lake Hartwell.

A capacitor plant on the river dumped PCBs into the stream between 1955 and 1977. Schlumberger Technologies Corp. bought the plant and is working to remove two other dams.

Officials hope sediment released by the removal of the dams will cover the contamination.
