The Department of Health and Environmental Control says some contamination from a Surfside Beach dog park is reaching the ocean, but is not causing any harm.
Debris from the Surfside Beach Bark Park flows into both Holly Lake and Myrtle Lake before eventually reaching the 5th Avenue North swash.
After complaints from two Surfside Beach residents who wish to remain anonymous, DHEC ran weekly tests on the swash's water between May and October 2012.
The levels of Enterococcus, which is a bacteria commonly found in fecal matter, failed DHEC standards on six out of 22 tests.
According to DHEC spokesman Jim Beasley, DHEC is working alongside the town of Surfside Beach to make sure water in the swash maintains safe levels of bacteria.
