Tap water quality in Charleston, South Carolina? Is it safe to drink?

The tap water quality in Charleston, South Carolina, demonstrates a mixture of reliability and areas that need attention. The primary water utility in the region is Charleston Water System, which serves most residents.

Water Quality Concerns:

1. Source: The majority of Charleston's water comes from the Edisto River and Bushy Park Reservoir. These surface water sources provide the essential water supply for the city's treatment plants.
2. Testing and Standards: The Charleston Water System tests the water rigorously to ensure it meets the Environmental Protection Agency (EPA) guidelines and the South Carolina Department of Health and Environmental Control (SCDHEC) standards. Despite these efforts, occasional lapses in quality have been reported, which necessitate periodic notifications to the public.
3. Water Hardness: The water in Charleston is classified as moderately hard. It contains minerals such as calcium and magnesium, which can accumulate in plumbing systems over time. This hardness is generally safe but may affect home appliances and fixtures.
4. Common Concerns: Some residents have raised concerns about the taste and odor of the water due to its mineral content. Additionally, the presence of chlorine used for disinfection can contribute to an off-putting scent. Seasonal variations, as well as occasional contaminants such as sediments or organic compounds, can influence the taste and visual clarity of the water.

Overall, while the tap water in Charleston is safe for consumption and everyday use, there are specific instances where residents might find it beneficial to take additional precautions. For those sensitive to the taste and hardness of the water, using water purifiers and water softeners is highly recommended. These devices can help in mitigating the effects of mineral buildup in appliances and improve the water’s overall taste, ensuring a more pleasant drinking experience.
