Inside the City of Alexandria, Virginia American Water reports total hardness from about 78 to 191 ppm, a spread that runs from moderately hard to hard depending on the season and source. A softener set to a tested number from your own tap handles that range well. Call the number on this page to be connected with a local plumber in Alexandria.
Who supplies your water, and what it carries
Virginia American Water serves the City of Alexandria, buying treated water from Fairfax Water, which draws from the Potomac River at its Corbalis plant and the Occoquan Reservoir at its Griffith plant. Its Alexandria report lists total hardness of 78 to 191 ppm, roughly 4.6 to 11 grains per gallon. Homes with an Alexandria mailing address in unincorporated Fairfax County, such as parts of 22306 to 22312 and 22315, are generally on Fairfax Water directly, so check which name is on your bill.
The water is disinfected with chloramine, with a temporary switch to free chlorine during Fairfax Water's spring flushing, roughly April through June. Many people notice a stronger chlorine smell then. A softener won't change that; a carbon filter will.
| Option | What it does | Best for |
|---|---|---|
| Salt-based softener | Removes calcium and magnesium by ion exchange | Whole-house scale control at the upper end of the range |
| Softener plus carbon stage | Softens and reduces disinfectant taste and odor | Households bothered by the spring chlorine change |
| Salt-free conditioner | Changes how scale forms; minerals stay in the water | Owners who want no brine discharge and accept partial results |
| Point-of-use filter only | Treats drinking water at one sink | Taste concerns without a scale problem |
Signs it's time
- Crusty buildup on faucet aerators and shower glass
- A water heater that crackles or takes longer to recover
- Spots on dishes even with rinse aid
- An older softener with a sticking valve, salt bridging or a brine tank that won't drain
Timing and seasonal notes
Hardness is not fixed. Because the supply blends river and reservoir water, readings drift through the year, which is why the report shows a range rather than one figure. Test at the kitchen tap before the unit is programmed, and again a few months later. Old Town houses often have tight basements and narrow utility rooms, so measure for the resin and brine tanks before buying. Installing before winter avoids running new lines in a cold crawlspace. Permit questions for work inside city limits go to the City's Department of Code Administration; county addresses go to Fairfax County.
