From bacteria to harmful algae, warmer waters bring changing risks
WRAL • • health
Key Points:
- A central North Carolina teenager recently died from a rare Naegleria fowleri amoeba infection, and two others died this year from Vibrio vulnificus bacteria, raising concerns about water safety in the state.
- Rising temperatures and longer-lasting summer heat have caused North Carolina’s lakes, rivers, and shallow waterways to stay warmer for extended periods, creating favorable conditions for harmful algae and microorganisms.
- While most local recreational water sites tested before Labor Day met safety standards, some areas showed elevated bacteria levels, prompting warnings to avoid discolored or scummy water that may indicate toxic algal blooms.
- Water utilities like Raleigh Water are preparing for increased algae-related issues due to warmer climates by using advanced treatment methods such as ozone to maintain water quality.
- State officials advise avoiding water with visible signs of algal blooms and recommend preventing warm freshwater from entering the nose to minimize the already rare risk of amoeba infection.
