North Myrtle Beach’s 2025 water quality report is largely a clean bill of health, with every routine contaminant coming in under its legal limit. The city’s water supply is a blend of surface water from the Grand Strand Water and Sewer Authority and a small amount from a local well.

Water Quality Results

The report shows that the water’s clarity, measured as turbidity, stayed under the strictest threshold in 100 percent of samples, and not a single routine sample tested positive for coliform bacteria. The numbers most families worry about were low, with lead registering a 90th-percentile value of 1.3 parts per billion against an action level of 15, and copper coming in at 0.14 against a limit of 1.3 parts per million.

However, two areas deserve a closer look. The disinfection byproducts, which form when chlorine reacts with natural organic matter, sat highest relative to their limits, with compliance averages around 31 parts per billion against ceilings of 80 and 60. The report also lists one actual violation, which was the city’s failure to send the state its certification confirming it had notified residents about older service lines.

PFAS and Future Compliance

The city’s 2024 samples for PFAS, also known as forever chemicals, showed PFOS averaging about 5 parts per trillion and PFOA about 4. This matters because the EPA has since finalized a limit of 4 parts per trillion for each, which means the PFOS result already sits above the standard the city will eventually have to meet.
