Work crews continued Monday to clean up a gasoline spill in a flood control channel near the Marine Corps Helicopter Air Station in Tustin, with officials predicting that it will be several days before the job is completed.
Kathleen Cha, spokeswoman for the Orange County Fire Department, said investigators have increased their estimate of how much unleaded gasoline was lost to 100,000 gallons from 60,000 gallons. The fuel spewed into the channel when an underground pipeline ruptured late Saturday.
"From this point on, it's very slow work," said Nira Yamachika, an environmental specialist with the county Environmental Management Agency.
She said the water level in the channel is being lowered gradually by pumps, so that the remaining gasoline can be vacuumed up.
