How hard is the water in Covington city, VA?
5.8 grains per gallon
Optional: a softener helps, but plenty of homes skip it.
The median hardness measured in Covington city, VA is 99 mg/L as calcium carbonate, which is 5.8 gpg. That is moderately hard on the USGS scale. It comes from 68 samples at 2 sites between 2001 and 2026, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 5.2 and 6.3 gpg. The whole middle of that range gives the same answer, so a test of your own tap is unlikely to change it. Confidence in the county figure: low (how it is measured).
What to do next
At 5.8 gpg this is your call. Look for white film on glasses and crust on the shower head: if you see little of either, you can live without one. If you do want one, a 24,000-grain unit is enough, so ask for that size rather than a bigger one.
