NEWPORT NEWS, Va. (WVEC) -- A swim advisory that was issued for Hilton Beach Wednesday has been lifted.

The advisory comes after samples showed that bacteria levels in the water were higher than the State Water Quality Standards.

The Peninsula Health District received results from re-sampling completed Wednesday indicating that bacteria levels in the water at Hilton Beach met the state water quality standards for recetational waters.

Beach water is checked routinely during the summer for bacteria levels, using indicator organisms such as enterococci.

The bacteria, known as enterococci, is a group of organisms used to determine the extent of fecal contamination of recreational waters. While these organisms do not cause illness, scientific studies indicate that their presence is closely correlated to the presence of other disease-causing organisms.

People swimming or playing in waters with bacteria levels higher than the standard have an increased risk of developing gastrointestinal illness.
