SACRAMENTO — Up to four million gallons of raw sewage seeped into the American River before it was detected over the weekend, said Sacramento County health officials.
The spill was detected Saturday but warning signs were not posted around the river beaches until Tuesday.

The county environmental health department didn’t find out about the spill until Monday and notified the parks department. Parks officials posted signs advising swimmers and waders to stay out of the water.
