Aerial view of the Chevron Empire, situated in Plaquemines Parish near the mouth of the Mississippi River, an area devastated by Hurricane Katrina. Around 991,000 gallons of oil were released, of which 983,000 gallons were naturally dispersed or evaporated. Around 4,000 gallons were recovered and a further 3,600 gallons were contained during the hurricane. This is 19 days after hurricane Katrina hit and devastation is evident, with villages and towns still flooded with contaminated water from the oil industries. Local residents and officials blame a ruptured Shell pipeline for spreading oil through marshes and communities down river from New Orleans.
