Well water softeners

Iron, manganese, and hardness on private wells need a lab or strip test first.

OpenStats municipal hardness across 343 cities helps estimate regional groundwater trends. Your own well still needs iron and hardness measured at the pump house or kitchen tap.

Keep iron under about 1 to 2 mg/L into a standard softener, or choose an iron-rated resin. A whole-house sediment and iron filter upstream protects valves and resin life.
