Crews with the East Bay Municipal Utility District were
working on a massive cleanup Thursday after an estimated 170 cubic yards of
concrete were accidentally dumped into a creek in the Oakland hills, officials
said.
The concrete drained into Glen Echo Creek near Mountain View
Cemetery around 11 a.m. Wednesday while utility district subcontractors were
back-filling 2 miles of an old 24-inch water pipe that had been replaced during
a large project that began last year, said agency spokeswoman Abby Figueroa.
Someone apparently left a valve open at the end of the
pipeline, causing the cellular concrete, a foamy type of material, to spill
into the creek, which ultimately drains into Lake Merritt.
