What this means for your home

Town of Harrisburg is the town's public water system; homes outside its lines may be on other systems or private wells.

Town of Harrisburg's report doesn't list hardness. Most reservoir-fed systems in this region are soft, but a quick hardness test at your tap is the only way to know before anyone recommends a softener.
Town of Harrisburg disinfects with free chlorine. If you notice the taste or smell, NSF/ANSI 42 certified carbon reduces it.
Disinfection byproducts (TTHM) were 64 ppb against an 80 ppb limit. That's compliant; some households still prefer a margin, which NSF/ANSI 53 carbon or reverse osmosis provides.
Town of Harrisburg reported PFOS at 10.3 ppt (highest single sample (2025)). EPA's enforceable limit for PFOA and PFOS is 4.0 ppt. Point-of-use filters certified to NSF/ANSI 53 or 58 for PFOA/PFOS reduce them at the tap.
Private wells aren't treated or monitored by a utility. North Carolina only requires a one-time test when a new well is built, so a current certified-lab test is the right starting point.
