How hard is the water in Newport News city, VA?
1.5 grains per gallon
You do not need a softener here.
The median hardness measured in Newport News city, VA is 26 mg/L as calcium carbonate, which is 1.5 gpg. That is soft on the USGS scale. It comes from 100 samples at 15 sites between 1993 and 2026, drawn from groundwater wells, which is what most taps and private wells in the county draw on.
How much it varies here
Half the sites came in between 1 and 5.3 gpg. That spread crosses a decision line, so some homes here land on a different answer. A $10 test strip on your own tap settles it. Confidence in the county figure: high (how it is measured).
What to do next
You can skip the softener. At 1.5 gpg the most a softener would fix is the odd water spot. If a salesperson in Newport News city says otherwise, ask to see their reading in grains per gallon and compare it with this one. Because Newport News city straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 0.7 to 13.8 gpg
The softest single sample on record in Newport News city was 12 mg/L and the hardest 236.5 mg/L, a 20-fold gap. The top quarter of sites read above 5.3 gpg and the bottom quarter below 1 gpg. So even in a soft county, a handful of wells here produce water hard enough to scale a heater.
Wells 1.5 gpg, rivers and lakes 3.9 gpg
100 groundwater samples from 15 wells put the median at 25.5 mg/L. 29 surface samples from 8 sites put it at 66.1 mg/L. In Newport News city the rivers and lakes come out 2.4 gpg harder. Here the surface water reads harder than the wells, which often points to streams fed by limestone springs or irrigation return flow. The two sources are close, so the county figure should hold whichever one your tap is on.
