What this means at home
At 149 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.

No reported violation does not prove that every contaminant was tested or absent; SDWIS measured values are incomplete and lag state records.
Solutions matcher
Matched to Malone ZIP 32445 using 149 PPM nearby hardness and 2 reported measurement benchmarks.
Scale protection
149 PPM is 1× the high-hardness trigger used by this matcher.

Frequently asked
EPA ECHO shows no active health-based violation for the associated systems in this reporting snapshot. This does not prove every contaminant is absent; federal records can lag and household plumbing can change tap conditions.
Nearby USGS observations produce an estimate of 149 PPM, or 8.7 grains per gallon, classified as hard. This is not a household tap measurement.
At 149 PPM, a correctly sized whole-house softener can reduce scale and hard-water spotting. It does not replace contaminant filtration.
