What this means for your home

Charlotte is inside Charlotte Water's service area on the state's water-system map.

Mountain Island gets the same Charlotte Water supply as the rest of the city, so the utility figures above apply here too. What differs from one neighborhood to the next is the plumbing inside the homes.
About 24.7% of homes in ZIP 28214 were built before 1980. If yours is one of them, a certified-lab lead test at the tap is worth doing before choosing a drinking-water system.
At 32 mg/L (about 1.9 grains per gallon), Charlotte Water water is soft. You very likely don't need a water softener.
Charlotte Water disinfects with free chlorine. If you notice the taste or smell, NSF/ANSI 42 certified carbon reduces it.
Disinfection byproducts (TTHM) were 63.7 ppb against an 80 ppb limit. That's compliant; some households still prefer a margin, which NSF/ANSI 53 carbon or reverse osmosis provides.

Mountain Island water questions

Is the water in Mountain Island different from the rest of Charlotte?

No. Mountain Island is on Charlotte Water like the rest of the city, with the same source lakes, treatment and reported results. Differences you notice at the tap usually come from your home's own pipes, fixtures or water heater.

Are homes in Mountain Island old enough to worry about lead?

Census estimates put about 24.7% of homes in ZIP 28214 as built before 1980. Lead usually comes from a home's own plumbing, not the utility, so in an older home a certified-lab test at the tap is the honest starting point.

Do I need a water softener in Mountain Island?

Almost certainly not. Charlotte Water reported hardness of 32 mg/L in its 2025 report, which is soft by USGS standards.

Do you serve Mountain Island?

Yes. Mountain Island is about 17 km from uptown Charlotte. Installation is performed by an independent, NC-licensed plumbing contractor under a separate agreement with you.
