South Carolina environmental officials say about 1 million gallons of untreated sewage have spilled into a York County creek that eventually flows into the Catawba River.
The Department of Health and Environmental Control says officials reported a sewer line break on Steele Creek near Fort Mill late Saturday. The agency began posting signs along Steele Creek and warning nearby residents on Monday.
DHEC is warning people to avoid contact with the creek and to keep pets out of its water in areas like the Anne Close Springs Close Greenway.
Officials say the spill should be diluted before it reaches the Catawba River about 10 miles away. DHEC says upcoming rains should also help diffuse the waste.
