City water: what your utility handles, and what's left for you to decide
What your utility already does
A municipal system pulls water from a lake, river or wells, treats it, adds a disinfectant so it stays clean on the way to your house, and samples it on a schedule set by state and federal rules. Every community water system has to send customers an annual drinking water quality report, also called a Consumer Confidence Report or CCR, by July 1 each year.[source] That report names the source, lists what was detected, and says whether the system had any violations.
Charlotte Water, for example, draws from Mountain Island Lake and Lake Norman, treats at three plants, and reported zero drinking water violations for 2025.[source] You can see its numbers, and those of other regional utilities, in our Charlotte-area water report, or look up your own address with the water lookup tool.

What's still worth considering at home
There are four honest reasons a city-water household looks at treatment. None of them requires a scare.
1. Chlorine taste and smell
Utilities keep a disinfectant in the water all the way to your tap. Charlotte Water's chlorine residual averaged 1.04 ppm in 2025, with a range of 0.47 to 1.60 ppm, under a 4.0 ppm limit.[source] Some people notice it, some don't. Our page on chlorine taste and odor explains which nearby utilities use free chlorine and which use chloramine, and what kind of carbon handles each.
2. Disinfection byproducts
When disinfectants react with natural organic matter they form byproducts such as trihalomethanes (TTHM) and haloacetic acids (HAA5), which EPA regulates.[source] Charlotte Water's highest locational running annual average for TTHM was 63.7 ppb in 2025, under the 80 ppb limit; HAA5 was 22.9 ppb against a 60 ppb limit.[source] If you'd rather have less in your drinking glass, certified carbon or reverse osmosis at the kitchen sink is the usual route.
3. Lead from home plumbing
Lead usually gets into tap water from service lines, solder and fixtures, not from the treatment plant.[source] Charlotte Water's 2025 lead 90th percentile was not detected, but one sampled home was above the 15 ppb action level.[source] That's why the only meaningful lead number is one taken at your own tap, through a certified-lab test. If it shows lead, look for a filter certified under NSF/ANSI 53 or 58 with a lead reduction claim.[source]
4. PFAS, where your utility reports it
Charlotte Water listed PFOA and PFOS as not detected in its 2025 monitoring.[source] A few other regional utilities reported PFOA or PFOS above 4.0 ppt. Our PFAS filtration page lists them with their actual numbers and the current federal status.
Things city water usually doesn't need
Most reservoir-fed systems around Charlotte are soft. A softener on Charlotte Water is very rarely worth the salt, space and upkeep, which is why it's on our list of things we won't sell you. Iron filters, sulfur treatment and UV disinfection are well-water tools; they don't belong on a properly disinfected municipal supply.

- Whole-home filtration: sediment and carbon at the point of entry for chlorine taste and smell in every tap and shower.
- Chlorine taste and odor: why utilities keep a residual, who uses chloramine, and which carbon handles what.

How we help on city water
- Step 1
Read your report together
We start with your utility's CCR, not a demo. If nothing in it bothers you, we'll say so.
- Step 2
Test what the report can't see
Lead and copper depend on your own plumbing, so a certified-lab test at your tap answers that.
- Step 3
Match treatment to the goal
Taste, byproducts, lead or PFAS each point to a different certified product category. We explain the options and leave out the ones you don't need.
- Step 4
Coordinate installation
Equipment that ties into your plumbing is installed by a licensed independent plumber. Here's how that works.
Questions we hear
Is Charlotte tap water safe to drink?
Charlotte Water reported zero drinking water violations for 2025, which means it met the standards it's tested against. Whether you want to treat it further is a preference question; our Charlotte page shows the numbers.
Where do I find my utility's water quality report?
Your utility must deliver it every year by July 1, and most post it online. EPA also has a search tool. We link each local report from the Charlotte-area water report.
Do I need a water softener on city water?
Usually not around Charlotte. Every local utility that reports hardness is in the soft range. See the city-water softener page for the numbers.
What's the most common thing city-water households actually buy?
A point-of-use filter or reverse osmosis system at the kitchen sink, because that's where most drinking and cooking water comes from. Whole-home carbon is the next step if chlorine smell in showers bothers you.
