How hard is the water in Gloucester County, VA?

0.8 grains per gallon

You do not need a softener here.

The median hardness measured in Gloucester County, VA is 14 mg/L as calcium carbonate, which is 0.8 gpg. That is soft on the USGS scale. It comes from 16 samples at 10 sites between 1996 and 2021, 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 2.4 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: medium (how it is measured).

What to do next

You can skip the softener. At 0.8 gpg the most a softener would fix is the odd water spot. If a salesperson in Gloucester County says otherwise, ask to see their reading in grains per gallon and compare it with this one.

From 0.3 to 10.3 gpg

The softest single sample on record in Gloucester County was 5 mg/L and the hardest 176 mg/L, a 35-fold gap. The top quarter of sites read above 2.4 gpg and the bottom quarter below 0.4 gpg.

Wells 0.8 gpg, rivers and lakes 5.4 gpg

16 groundwater samples from 10 wells put the median at 13.5 mg/L. 47 surface samples from 4 sites put it at 91.8 mg/L. In Gloucester County the rivers and lakes come out 4.6 gpg harder. Here the surface water reads harder than the wells, which often points to streams fed by limestone springs or irrigation return flow. A utility here that draws from the aquifer can deliver noticeably different water from a private well next door.
