What this means for your home

At 4.9 mg/L (about 0.3 grains per gallon), Greenville Water water is soft. You very likely don't need a water softener.
Greenville Water's report lists chloramine as its disinfectant. Chloramine is more stable than free chlorine, so if you want to reduce it, choose catalytic carbon certified for chloramine reduction rather than a basic chlorine filter.
Disinfection byproducts (TTHM) were 16.4 ppb against an 80 ppb limit. That's compliant; some households still prefer a margin, which NSF/ANSI 53 carbon or reverse osmosis provides.
