Monitoring Frequency

Source Information

Charleston Waterkeeper’s Recreational Water Quality Monitoring Program regularly tests the “swimmability” of several local tidal creeks and hotspots for activities like swimming, SUPing, kayaking, and sailing. Every Wednesday from May through October samples are collected and analyzed for the amount of Enterococcus bacteria present. Testing results are posted to Swim Guide every Thursday afternoon or as soon as they are available.

The State of South Carolina’s water quality standard for water-based recreational activity is 104 MPN/100 mL. Swimming and other full body contact recreational activity is not recommended in areas where the most recent testing shows Enterococcus bacteria counts of 104 MPN/100 mL or higher.

Sample site locations are color coded in Swim Guide as follows:

A “Green” site = test result of 103 MPN/100 mL or lower.
A “Red” site = test result of 104 MPN/100 mL or higher.
A “Gray” site = no test result
