Virginia Beach, VA water hardness
Virginia Beach Department of Public Utilities publishes an average hardness of 56 mg/L for its system, in its City of Virginia Beach 2026 Water Quality Report. On the USGS scale that is soft water, though the utility's own range crosses more than one class — it spans soft and moderately hard water from end to end.
The published figure, exactly as it appears
This is the hardness line transcribed from the source, with nothing added:
ADDITIONAL INFORMATION Substance Range Average Level Unit […] Hardness 48-74 56⁴ ppm […] (4) The water averages in the range between soft and slightly hard. […] To find grains per gallon, divide ppm value by 17.

Virginia Beach hardness in mg/L and grains per gallon
Water-quality reports use mg/L (identical to ppm). Softener instructions and plumbing specifications use grains per gallon. Both are below. Where a figure is our arithmetic rather than the utility's own number, it says so.
| Figure | mg/L (ppm) | Grains per gallon | Whose number |
|---|---|---|---|
| Published average | 56 | 3.3 | mg/L published, gpg is our conversion |
| Low end of published range | 48 | 2.8 | mg/L published, gpg is our conversion |
| High end of published range | 74 | 4.3 | mg/L published, gpg is our conversion |
| Plotted on the scale above | 56 | 3.3 | published average; the gpg here is our conversion at 17.1, so it can differ slightly from a utility’s own rounded gpg figure |
The conversion, both ways: gpg = mg/L ÷ 17.1 and mg/L = gpg × 17.1. Worked for this system: 56 ÷ 17.1 = 3.3 gpg. The converter does °dH and °f as well, and why the factor is 17.1 explains where the number comes from.

Notes the report forces on this page
- Virginia Beach's footnote converts with a divisor of 17, as the hardness footnote in Norfolk's report also does; this site uses 17.1. Grains-per-gallon figures on this page are this site's conversion at 17.1.
- Virginia Beach buys its water from Norfolk, but its own report gives a different hardness range and average (48-74, average 56 ppm) from Norfolk's (32 – 74, average 48 ppm). Each city's page carries its own report's figures.
If you are sizing a softener for Virginia Beach water
At 3.3 gpg, the sizing arithmetic starts from your household's water use, not from the hardness alone. The calculator below is pre-filled with this system's figure and every other input is an editable assumption.
Whether a softener is worth installing at this hardness is a judgement, not arithmetic, and it is not one this site makes for you. Nothing here has been tested by the author.
