• Beach Monitoring and Advisories 2017

    Virginia Department of Health (VDH) monitors bacteria levels in beach water at 46 public beaches on the Chesapeake Bay and the Atlantic Ocean during the swimming season (May-September).
    Weekly water samples are collected by local health departments and analyzed by local laboratories for enterococci bacteria levels. Any bacteria level exceeding Virginia's Water Quality Standard of 104 colony forming units (cfu)/100 mL of water requires the issuance of a swimming advisory. Enterococci bacteria serve as an indicator for fecal contamination in salt/brackish waters; while not harmful themselves, enterococci bacteria indicate that other potentially harmful organisms may be present.

    High levels of enterococci bacteria indicate an increased health risk to recreational water users. Swallowing water contaminated by these disease-causing organisms can cause the most common recreational water illnesses, which are gastrointestinal and may cause vomiting, diarrhea, nausea, abdominal pain or fever. Contact with contaminated water can also cause upper respiratory (ear, nose, and throat), and wound infections. The elderly and young children, as well as those with weakened immune systems are particularly vulnerable to recreational water illnesses.
