The South Carolina Air Monitoring Network provides information on SCDHEC's current and historical air monitoring stations, information on pollutants sampled, objectives and historical concentrations. Links to explanation of standards are provided.

Image for Beach Advisory Application BEACH ADVISORIES

The Beach Advisory application provides up-to-date information on advisories. If a high bacteria count is found an advisory is issued for that portion of beach. Advisories do not mean that the beach is closed. Wading, fishing, and shell collecting do not pose a risk. Advisories are lifted when sample results fall below the acceptable limit.

The South Carolina Beachfront Jurisdiction web application was developed to enable efficient access to key information by coastal stakeholders and decision-makers. Users of the application can quickly navigate to specific beaches or properties, view state jurisdictional line locations and adopted long-term erosion rates. Technical users of the site may also download beachfront survey information packets, which contain jurisdictional line coordinates and survey monument locations.
