Wastewater Disposal Facility in Colorado
Oilfield waste arrives by tanker truck at a wastewater disposal facility near Platteville, Colo. After removal of solids and oil, the wastewater is injected into a deep well for permanent storage underground. This disposal process has the potential to trigger earthquakes, but very few wastewater disposal wells produce earthquakes.

Deep-Sea, Cold Water Coral
Close-up image of the cold-water coral Lophelia pertusa, with polyps extended. The coral polyps eat by grabbing tiny suspended particulates (visible against the dark water background). The bright orange claws of a squat lobster (Eumunida picta) can be seen peeking out from behind the coral branches.
