Travis reports no ‘petroleum’ sheen on Union Creek since December
Travis Air Force Base officials reported the “petroleum” sheen that has appeared on Union Creek a number of times, usually after rain events, has not been seen since December. That includes after the most recent storm, Capt. Jasmine Jacobs, with the base Public Affairs Office, said in an email response to the Daily Republic. Jacobs led a site visit with the Daily Republic on Feb. 27. Leslie Pena, the civilian environmental element chief at Travis, was part of the tour. This week the base confirmed for the first time that testing has shown that aviation fuel, motor oil, gasoline and diesel have been present, but the source of the leak is still under investigation.
