What this means at home
At 47.6 PPM, mineral scale can build up on fixtures and heating elements, reduce soap lather, and leave visible spotting. Hardness is primarily an aesthetic and appliance concern—not itself a tap-water safety rating.

Frequently asked
Water questions for Tatum
Is tap water safe in Tatum?+
