The canister had been lost by the company's transport partner, when the improperly secured container fell off the trailer on which it was being transported. In 2010, the Aberdeen Sheriff court fined Schlumberger Oilfield UK £300,000 for losing a radioactive source on the rig floor on the Ensco 101 mobile drilling rig in the North Sea for four hours. ===Spills=== In 2009, the Pennsylvania Department of Environmental Protection fined Chesapeake Appalachia LLC and Schlumberger Technology Corp. more than $15,500 each for a hydrochloric acid spill in February 2009 at Chesapeake's Chancellor natural gas well site in Asylum Township, Bradford County, Pennsylvania. Officials said the leak did not contaminate groundwater. ===PCB contamination=== In 2006, as the current owner of a facility in Pickens, South Carolina, Schlumberger agreed to pay $11.8 million to federal and state agencies for a problem caused by the previous owner, Sangamo-Weston, a capacitor manufacturing plant. The cause of the problem was from polychlorinated biphenyls (PCB) released into the environment by Sangamo-Weston from 1955¹ to 1987. According to the Justice Department's Environment and Natural Resources Division, an additional agreement by Schlumberger to purchase and remove dams will directly improve the Twelvemile Creek, South Carolina ecosystem and provide significant environmental benefits for the affected communities.
