An intermittent oil sheen is visible along the stormwater drainage ditch area of Union Creek, Aug. 23, 2023, at Travis Air Force Base, California. Sheens can be caused by a number of things including petroleum products interacting with the water as well as naturally occurring environmental events, such as the decomposition of plants.
