City water vs. well water in Cherokee County
Cherokee's public water is among the lowest in hardness in North Metro Atlanta — the county authority publishes 0.94 grains per gallon. So on county or city water, the thing to address is chlorine and the byproducts it forms. Carbon filtration is built to reduce both, and a softening stage is a light finish that keeps scale off your water heater and fixtures over time rather than solving a hardness problem.
North Cherokee and the areas around Canton still have plenty of private wells. Well water there can carry iron, manganese and a sulfur smell, and there's no disinfectant in the line. For a well we recommend the Dual Tank — Well Water with a UV purifier, and we always ask for a certified lab test first so the system is matched to your water.
Systems we recommend here
For most homes on Cherokee County, Woodstock or Canton water, the Complete Home Package ($2,599) is our first recommendation: whole-house carbon filtration and softening, plus the HW800 AlkaPro Tankless RO ($999 on its own) for drinking and cooking water at the kitchen sink. On a private well, the Dual Tank — Well Water ($3,499) is built to reduce iron, manganese and sulfur smell, and the Whole-Home UV Purifier ($599) adds chemical-free disinfection, since wells have none in the line. All prices are system only.
