Advisory Posting Procedures

The City of North Myrtle Beach follows the protocol for posting beach advisories as developed by SCDHEC. In addition, the City will post precautionary advisories as issued by local DHEC/EQC staff.
Advisory postings are placed on the beach at the sample location if a water quality concern is indicated, as follows:
	When a single sample exceeds 500 (Enterococci)
	When consecutive daily samples exceed 104 (Enterococci)
If an advisory is posted, swimming is not recommended within 100 feet of the site. Other activities, such as shell hunting, walking/wading in the surf are not affected. Click for Advisories.
