State recreational water quality officials today lifted a water quality swimming advisory at a sound-side site in Dare County.
The advisory was lifted because water testing shows that bacteria levels have dropped to within the state’s and Environmental Protection Agency’s standards set for swimming and water play.
The advisory was posted on Sept. 18 at Jockey's Ridge Sound-side Access in Nags Head. At the time, tests of water samples taken at the site showed a monthly average of the bacteria enterococci above the EPA-mandated level of 35 enterococci per 100 milliliters of water, the standard for high-use sites. Subsequent testing at this site found that bacteria levels have fallen below the standard. The sign advising against swimming, skiing or otherwise coming into contact with the water has been removed.
Enterococci, the bacteria group used for testing, are found in the intestines of warm-blooded animals. While it is not known to cause illness, scientific studies indicate that enterococci may indicate the presence of other disease-causing organisms. People swimming or playing in waters with bacteria levels higher than the standards have an increased risk of developing gastrointestinal illness or skin infections.
Coastal recreational waters in North Carolina are generally clean. However, it is important to continue monitoring them, so we can inform the public of any localized problems. The N.C. Recreational Water Quality Program samples 209 sites in coastal waters of the state, most of them on a weekly basis from April through October.
