What this means at home
At 292 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.

Water questions for Osage Beach
Is tap water safe in Osage Beach?+
