"Adam Wraight pulled a blue sewage "warning" sign out of the sand near Imperial Beach Pier on Thursday morning, replacing it with the more ominous yellow and red placard telling beachgoers that waters were officially closed.
"There's more than just the normal ooze that's coming?" asked Imperial Beach native Colette Dominguez who happened to walk by.
"It's an active spill," explained Wraight, a marine safety sergeant with the city's lifeguards. "A big pipeline broke."
Shorelines from the border up through Coronado were closed to swimming Thursday as the result of a pipeline that ruptured in Tijuana near Smuggler's Gulch over the weekend. Sewage has been spilling over the border into the river's estuary for days, but it's just now making its way to the ocean and floating up the coast on surging northward currents."
