The United States-Mexico border region is enduring the latest in a series of massive cross-border sewage tainted spills.

Federal officials in charge of monitoring the trans-border sewage situation on the U.S. side of the border said nearly 8 million gallons of tainted water flowed crossed the border in the Tijuana River channel.

The flow crossed the border from 7 p.m. Sunday evening through 10 a.m. Monday.
