How hard is the water in Bristol city, VA?

13.4 grains per gallon

A softener will pay its way here.

The median hardness measured in Bristol city, VA is 229 mg/L as calcium carbonate, which is 13.4 gpg. That is very hard on the USGS scale. It comes from 187 samples at 13 sites between 1998 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 13.2 and 13.5 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: high (how it is measured).

What to do next

At 13.4 gpg a softener pays its way here. Before you buy, check the quoted unit's grain capacity against the sizing table below, and ask whether it regenerates on demand, which uses less salt than a timer. Call your utility for its own report if you are on city water.
