How hard is the water in Suffolk city, VA?
0.9 grains per gallon
You do not need a softener here.
The median hardness measured in Suffolk city, VA is 15 mg/L as calcium carbonate, which is 0.9 gpg. That is soft on the USGS scale. It comes from 107 samples at 31 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 0.4 and 2.1 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
You can skip the softener. At 0.9 gpg the most a softener would fix is the odd water spot. If a salesperson in Suffolk city says otherwise, ask to see their reading in grains per gallon and compare it with this one.

From 0.2 to 292.1 gpg
The softest single sample on record in Suffolk city was 3.1 mg/L and the hardest 5,000 mg/L, a 1,613-fold gap. The top quarter of sites read above 2.1 gpg and the bottom quarter below 0.4 gpg. So even in a soft county, a handful of wells here produce water hard enough to scale a heater.
Wells 0.9 gpg, rivers and lakes 1.2 gpg
107 groundwater samples from 31 wells put the median at 15 mg/L. 93 surface samples from 21 sites put it at 20.3 mg/L. In Suffolk city the rivers and lakes come out 0.3 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.
