What this means at home
At 360 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.

Frequently asked
Water questions for Angola
Is tap water safe in Angola?+
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.
How hard is the water?+
Nearby USGS observations produce an estimate of 360 PPM, or 21.1 grains per gallon, classified as very hard. This is not a household tap measurement.
Do I need a water softener?+
At 360 PPM, a correctly sized whole-house softener can reduce scale and hard-water spotting. It does not replace contaminant filtration.
