Why must the Department of Health and Environmental Control (DHEC) issue a Boil Water Advisory in preparation for a hurricane?

State drinking water regulations require DHEC to issue a Boil Water Advisory for the affected geographic areas before a Hurricane makes landfall. Because a hurricane may cause damage to the water system that may make the water unsafe to drink, and because the hurricane may disrupt methods of public notification after a storm, the advisory must be issued before the hurricane strikes. 

After the storm, you should stay tuned to radio reports for further instructions. Williamsburg County Water Authority will dispatch crews to begin surveying damage and making repairs immediately after the storm. If sampling shows that the water has been contaminated by bacteria Williamsburg County Water Authority, will issue a Boil Water Notice; if tests show the water is safe to drink, Williamsburg County Water Authority will lift the advisory.
