Water samples from around Huntington put hardness at about 137 mg/L (8.0 gpg), which would be hard on the USGS scale. Treat this as a rough guide: it is the median of 201 samples taken across Cabell County, mostly wells and streams, not a test of Huntington's treated tap water. One more reason for caution: EPA lists Huntington's water system as using surface water, which is often softer than the wells behind the county figure.
Huntington sits 31 mg/L above the typical West Virginia figure of 106. Of the 10 nearest cities we track, 9 have softer water and 1 has harder. The range nearby runs from 41 mg/L in South Charleston to 228 in New Martinsville.
What 137 mg/L means at home
Expect white crust on faucets and showerheads, plus spots on dishes that come out of the dishwasher.
Kettles collect scale quickly. Water heaters build up sediment at the bottom of the tank, which makes them work harder over time.
Soap and detergent need a little more to lather, and soap scum shows up in the tub.
Hardness is not a health problem, and EPA sets no limit for it. It is a matter of scale and soap.
What to do about it
At 137 mg/L most of the trouble is scale, and only a few things deal with it.
Ion-exchange water softener
The standard whole-house fix. It swaps calcium and magnesium for sodium or potassium and needs salt plus a drain. Size it with the calculator below.
Salt-free conditioner
No salt and no drain line. It changes how minerals form scale instead of removing them, so water still tests hard.
Reverse osmosis or carbon filter
Under-sink reverse osmosis removes minerals from drinking water only. Plain carbon filters improve taste but do not soften.
3 people × 75 gallons a day × 8.0 gpg = 1,798 grains a day. A 24,000-grain unit regenerates about every 13 days.
