A mysterious oil slick has washed ashore on Viet Nam's central coast from the Da Nang area north to near the city of Hue and Thua Thien and Quang Tri provinces (ed. note: this is the area I was stationed at in 1970-71 during the Viet Nam war; I know it well although I never frolicked on the beaches).
To date the oil slick had washed ashore on 120 kilometers of shoreline, mostly beaches.
The source of the oil slick is unknown -- it could have come from an offshore oil drilling rig, a sinking tanker or more likely a tanker intentionally pumping its sludge into international waters. Helicopters sent to search for the source of the spill only found more oil slicks. The oil has been tentatively identified as fuel oil. Hundreds of people were mobilized to clean the oil from the beaches with 500 people working 16 hours cleaning up 60 tons of oil from beaches at Hoi An.
