State officials say preliminary slurry water samples pulled from the acre of swampland that liquefied into muck over the weekend indicate the presence of small amounts of diesel hydrocarbons.
The pond of muck, located in Assumption Parish, first appeared Friday night and grew quickly, bending a 36-inch natural gas pipeline buried 16 feet in the ground as the muck expanded. About 150 homes and several businesses were ordered to evacuate after Gov. Bobby Jindal declared a state of emergency for the parish when the slurry area appeared to be expanding.

State officials say a stinky smell reported from Bayou Manchac last week stems from stagnant swamp water in Spanish Lake that heavy rains pushed into the bayou.

Mallett said the stagnated water washed through Alligator Bayou to Bayou Manchac.
