The Swift Creek Landslide is an active, slow-moving landslide located in western Washington, USA, due east of Everson on Sumas Mountain. Asbestos-laden sediment originating from the landslide has recently generated much interest in this area. Asbestos is a known carcinogen. EPA sampling has documented asbestos in sediments in Swift Creek and in downstream Sumas River. Average asbestos levels in Swift Creek dredged material exceed the level that, in construction materials, triggers worker safety requirements and material handling and disposal regulations.
