Is Charlotte water safe? What is actually in it? Straight answers from Charlotte Water's own 2025 report, and what they mean for your home.

Quick answer
Charlotte Water reported zero violations for 2025. Trihalomethanes, a disinfection byproduct, ran closest to the limit at up to 77.4 ppb against an 80 ppb federal limit, and EPA sampling found low levels of PFAS. Whole-home carbon filtration reduces byproducts at every tap; reverse osmosis is the most effective way to remove PFAS from drinking water.
Charlotte Water draws from Lake Norman and Mountain Island Lake and serves the Mecklenburg County service area. These are 2025 results from its Consumer Confidence Report.
| Measure | Charlotte 2025 | Range | Limit |
|---|---|---|---|
| Total trihalomethanes (TTHM) | 63.7 ppb (highest running average) | 17.2 to 77.4 ppb | 80 ppb |
| Haloacetic acids (HAA5) | 22.9 ppb (highest running average) | 10.4 to 24.5 ppb | 60 ppb |
| Disinfectant residual (chlorine) | 1.04 ppm | 0.47 to 1.60 ppm | 4.0 ppm |
| Fluoride | 0.65 ppm | 0.04 to 0.81 ppm | 4 ppm |
| pH | 8.5 | 7.4 to 9.5 | 6.5 to 8.5 (secondary) |

Charlotte's highest running average for total trihalomethanes was 63.7 ppb in 2025, with individual results up to 77.4 ppb, against a legal limit of 80. These disinfection byproducts form when chlorine reacts with organic matter from the lakes, and they are what most people taste and smell in the shower.
They are legal, but they are the clearest reason Charlotte homes filter. Whole-home carbon filtration reduces them at every tap; reverse osmosis handles drinking water at the sink.
Charlotte Water reports that it tests for more than 70 PFAS compounds and that most levels in its system are undetectable or well below federal thresholds. In EPA's required UCMR 5 sampling (2023 to 2024), PFPeA averaged 0.67 ppt and PFBA 0.75 ppt.
If you want PFAS out of your drinking water entirely, reverse osmosis is the most effective home option.
On city water: whole-home carbon filtration for chlorine taste and disinfection byproducts, plus reverse osmosis for drinking water, and a softener or salt-free conditioner where the test shows hardness. Homes on wells outside the Charlotte Water system need their own test; iron and sulfur are common. See our Charlotte service page for systems and service areas.
Charlotte Water reported zero violations for 2025. Disinfection byproducts are present below their legal limits, with trihalomethanes running closest to the limit. Many households filter drinking water anyway.
It depends on your home. Hardness varies with your plumbing, your water heater and whether you are on a private well. Our free in-home test measures it on the spot; if you are seeing scale, spots or dry skin, a softener or salt-free conditioner fixes it, usually paired with whole-home carbon for chlorine and byproducts.

Charlotte Water says most PFAS levels in its system are undetectable or well below federal thresholds. Low levels of PFPeA and PFBA were found in EPA's 2023 to 2024 sampling.
