CHARLOTTE, N.C. (AP) - Nearly 5 million gallons (19 million liters) of sewage has spilled into a creek in North Carolina.
Local media reported Charlotte's water system said the spill occurred when a tree broke a 36-inch (1 meter), underground pipe after storms Monday.
The water system says the spill flowed into Mallard Creek near the University of North Carolina Charlotte.
Crews have controlled the leak but said it could take two to three days to repair the pipe.
Health officials say the spill does not pose any immediate threat to downstream drinking water or recreational waters.
Crews at a sewage treatment plant noticed a reduced flow of material into the plant Tuesday and traced the system upstream until they found the broken pipe.
The Charlotte Observer reported it's the largest spill since 2003.
