Ballantyne Water Treatment
Water Treatment for Ballantyne, NC Homes
Ballantyne gets its water from Charlotte Water, treated at plants well north of here in west Charlotte and Huntersville. Here is what the utility's own 2025 report says about that water, what it means for your home, and what a free in-home test adds.
Is Ballantyne, NC tap water safe to drink?
Yes, by federal standards. Ballantyne is served by Charlotte Water (system NC0160010), which reported zero drinking water violations for 2025. The water comes from Lake Norman and Mountain Island Lake and is disinfected with chlorine, with a residual averaging 1.04 ppm. Every regulated contaminant in the 2025 report was under its limit. The one with the least room was total trihalomethanes, a chlorine byproduct, at 63.7 ppb, the highest yearly average at any test site, under the 80 ppb limit. EPA's UCMR5 monitoring also found two short-chain PFAS, PFBA and PFPeA, at averages under 1 part per trillion; neither has a federal limit. Hardness averages 32 ppm, about 1.9 grains per gallon, so the water is soft. For most Ballantyne homes, the treatment question is chlorine taste and byproducts, not hardness. A free in-home test then shows what your own pipes add.

What Charlotte Water's 2025 report says about Ballantyne's water
Ballantyne is a Charlotte neighborhood in the far south of Mecklenburg County, so it is served by Charlotte Water (system NC0160010) like the rest of the city. Charlotte Water draws from Lake Norman and Mountain Island Lake on the Catawba River and treats an average of 125 million gallons a day at three plants: Franklin, Vest, and Dukes. The water is disinfected with chlorine, not chloramine, and the 2025 report lists zero drinking water violations. Hardness averages 32 ppm, about 1.9 grains per gallon, which is soft. The numbers that matter more for a Ballantyne home are the chlorine residual (1.04 ppm system average, up to 1.60), disinfection byproducts (total trihalomethanes: the highest yearly average at any test site was 63.7 ppb, under the 80 ppb limit), and two short-chain PFAS found at low parts-per-trillion levels.
Why Ballantyne's location matters for its water
All three Charlotte Water treatment plants are well north of Ballantyne: Franklin and Vest in west Charlotte and Dukes in Huntersville. Ballantyne is at the county's southern edge along the South Carolina line, so its water has traveled a long way through the utility's 4,664 miles of pipe by the time it reaches a tap on Ballantyne Commons Parkway. Charlotte Water reports disinfection byproducts by monitoring site rather than by neighborhood, so no published number is specific to Ballantyne. That is one reason HydroSmart tests at your own tap before recommending anything. Ballantyne homes are on city water, so the iron, sulfur, and well-water issues common further out in Union County usually do not apply here.
Ballantyne is part of the wider Charlotte metro HydroSmart serves. See the full water treatment charlotte nc page.

The local contaminants most likely to get attention in Ballantyne
Disinfection byproducts: the number closest to its limit
Total trihalomethanes (TTHM) form when chlorine reacts with natural organic matter, and they keep forming as water moves through the pipes. Charlotte Water's highest yearly average at any test site was 63.7 ppb (individual samples ranged from 17.2 to 77.4 ppb), under the federal limit of 80 ppb. That is compliant, and it is also the regulated number with the least headroom in the report. Catalytic or activated carbon filtration is the standard in-home reduction step.
PFBA: a short-chain PFAS found at low levels
EPA's UCMR5 monitoring (samples from August 2023 to May 2024) found PFBA in Charlotte Water at an average of 0.75 parts per trillion, with a highest sample of 9.7 ppt. PFBA has no federal limit.
PFPeA: the second PFAS in the federal data
The same UCMR5 samples found PFPeA at an average of 0.67 ppt, with a highest sample of 3.4 ppt, also with no federal limit. PFOA and PFOS, the two PFAS with federal limits, do not appear in the report's tables of detected contaminants.
What the free in-home test measures
The report above describes the whole system. The in-home test describes your house, including anything your own pipes and fixtures add.
- Hardness (calcium and magnesium)
- pH
- Chlorine
- Iron
- Total dissolved solids (TDS)
- Nitrates
Results are explained the same day. The in-home test does not measure PFAS or disinfection byproducts; those need a certified lab, which is why the PFAS and byproduct figures on this page come from Charlotte Water's lab data.

How HydroSmart approaches Ballantyne
Whole-home carbon filtration for chlorine and byproducts
A carbon-based whole-home system reduces chlorine taste and smell and disinfection byproducts at the point of entry, so every shower and tap gets the same water. For Charlotte Water, this is usually the first system worth considering.
See whole-home options →Reverse osmosis at the kitchen tap
An under-sink reverse-osmosis system reduces metals your own plumbing can add to the water you drink and cook with.
See drinking-water systems →Carbon and reverse osmosis, sized to your home
If you want both whole-home and drinking-water treatment, HydroSmart combines carbon and reverse-osmosis stages based on how your household uses water. The recommendation comes after the in-home visit, not before.

Ballantyne water treatment FAQ
Is Ballantyne, NC tap water safe to drink?
By federal standards, yes. Charlotte Water, which serves Ballantyne, reported zero drinking water violations for 2025, and every regulated contaminant in its 2025 report was below its limit. The closest to a limit was total trihalomethanes, a chlorine byproduct, at 63.7 ppb, the highest yearly average at any test site, under the 80 ppb limit. Many homeowners still filter for chlorine taste and byproducts.
Does Charlotte Water use chlorine or chloramine?
Chlorine. Charlotte Water's 2025 Consumer Confidence Report says it adds chlorine to prevent bacterial growth and reports a chlorine residual averaging 1.04 ppm across the system (range 0.47 to 1.60 ppm), well under the 4.0 ppm maximum. That matters when you choose a filter, because standard activated carbon handles chlorine well.
Why does my Ballantyne tap water smell like chlorine?
Charlotte Water keeps a chlorine residual in the pipes so the water stays disinfected all the way to your tap. Its 2025 report shows that residual ranging from 0.47 to 1.60 ppm, and some people notice it at the higher end. A carbon filter, either whole-home or at the kitchen tap, removes most of the taste and smell.
Do Ballantyne homes need a water softener?
Usually not for hardness alone. Charlotte Water's total hardness averaged 32 ppm in 2025 (range 27 to 35 ppm), about 1.9 grains per gallon, which is soft water. If you are seeing scale, the free in-home test will show whether hardness is really the cause at your address.
Is there PFAS in Ballantyne's water?
Low levels of two short-chain PFAS. EPA's UCMR5 monitoring of Charlotte Water found PFBA (average 0.75 ppt, highest 9.7 ppt) and PFPeA (average 0.67 ppt, highest 3.4 ppt). Neither has a federal limit, and PFOA and PFOS are not in the report's detected-contaminant tables.
What does HydroSmart's free in-home water test check?
The in-home test covers hardness, pH, chlorine, iron, total dissolved solids, and nitrates at your tap, and you get the results the same day. It does not measure PFAS or disinfection byproducts. Those need a certified lab, so for them this page uses Charlotte Water's own lab results.
How can I check whether my Ballantyne home has a lead service line?
Charlotte Water publishes its service line inventory at charlottewaterlead.org, and you can request a lead test by calling 311 or 704-336-7600. In its 2025 sampling, the 90th-percentile lead result was non-detect, with one site above the 15 ppb action level. Lead usually comes from home plumbing, not the water main, so the result can vary from house to house.
Is HydroSmart a Home Depot partner?
Yes. HydroSmart is a Home Depot Home Services partner, and our team works in-store at Home Depot locations in the Charlotte area, including the store on Ballantyne Commons Parkway. You can book the same free in-home water test here on the website or at the store.
Does Ballantyne have its own water system?
No. Ballantyne is a Charlotte neighborhood, not a separate town, so it is on Charlotte Water's citywide system (NC0160010). Every water-quality figure on this page is from Charlotte Water's 2025 Consumer Confidence Report or EPA's UCMR5 monitoring of that system.
