What this means at home

At 19.5 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 Charleston

Is tap water safe in Charleston?+

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 19.5 PPM, or 1.1 grains per gallon, classified as soft. This is not a household tap measurement.

Do I need a water softener?+

There is no high-hardness trigger in this profile. Confirm with a tap test before buying equipment.
