Coast Guard cleaning up tar balls on S.C. beaches

CHARLESTON (AP) – The Coast Guard is cleaning some beaches on the South Carolina coast after tar balls were spotted on the shore.

The Coast Guard said teams on Edisto Island and Seabrook Island found tar balls Sunday morning. The Coast Guard says it is continuing an oil spill assessment and is working with contracted crews to clean the Charleston area beaches.

An oil spill was reported in Charleston Harbor on Oct. 20. The Coast Guard says it hasn't heard reports of the oil causing problems for fish or wildlife. The Coast Guard says cleanup efforts on Sullivans Island, Folly Beach and Fort Sumter have been effective.

Authorities say they have not determine the source of the oil but have several samples to test. The tests were not expected to be finished until late this week.
