Charleston faces serious water quality challenges due to climate change and heavy rainfall. As Andrew Wunderley, the executive director of Charleston Waterkeeper, points out, an increasing number of sewage treatment authorities attribute sanitary sewer overflows (SSOs) to intense storms.
A notable example is Tropical Storm Debby, which hit South Carolina in August 2024. Testing showed a surge in enterococcus levels after the storm. This bacteria, common in fecal matter, serves as a key indicator of water contamination. In Charleston, levels exceeded the state’s safe swimming limit of 104 colony-forming units per 100 milliliters. Some areas reported astounding levels—over 24,000 cfu/100mL.
The increase in contamination isn’t solely from sewer overflows. Factors such as animal waste from farms and leaky septic tanks also play a role. For instance, in areas like James Island Creek, flooding exacerbates the problem, washing in bacteria from different sources.
According to recent studies, more than 70% of coastal communities nationwide are experiencing similar issues due to climate change. Rising sea levels and intense storms lead to overwhelmed water systems and increased contamination risk.
A broader look at trends shows that social media users are increasingly discussing water safety and pollution, especially during storm season. People want to know if it’s safe to swim and how to protect themselves and their families.
Addressing these challenges requires a collective effort from communities, policymakers, and environmental organizations. Regular monitoring, better waste management, and informed public awareness can help mitigate risks and improve water quality for everyone.
