At 35 mg/L (about 2 grains per gallon), City of Rock Hill water is soft. You very likely don't need a water softener.
City of Rock Hill uses chlorine dioxide along with chlorine. If you notice a chlorine taste or smell, NSF/ANSI 42 certified carbon reduces it.
Disinfection byproducts (TTHM) were 52 ppb against an 80 ppb limit. That's compliant; some households still prefer a margin, which NSF/ANSI 53 carbon or reverse osmosis provides.
27.7% of homes in Lesslie were built before 1980. EPA notes homes built before 1986 are more likely to have lead in their plumbing, so a certified-lab lead test at the tap is a sensible first step in an older home.
