Calls Mount For Investigation Into Massive Tijuana River Sewage Spill

Lawmakers, regulators and environmental groups in San Diego County are calling on federal officials to investigate a massive sewage spill in the Tijuana River that some people believe Mexico may have intentionally caused and then refused to explain much about it. Mexican authorities have yet to give a full accounting of how, without advance notice, an estimated 143 million gallons of effluent spewed into the river during 17 days that ended on Feb. 23.
