Virginia Tap Water: Northern Virginia Runs Hard
Northern Virginia tap water comes from treated Potomac River and Occoquan Reservoir water and meets federal and state standards. Fairfax Water does note, though, that its water runs moderate to hard.
U.S. Geological Survey (USGS) scale: 0–60 soft, 61–120 moderate, 121–180 hard, 181+ very hard. Fairfax Water figures reflect its published 5–10 gpg range; Newport News is the 2025 average.

Scale and White Spots
Fairfax Water explains that white spots on coffee pots and glasses come from minerals like calcium. Split the job: a purifier for drinking water, a softener for household water.
A Disinfection Method That Changes with the Seasons
Fairfax Water uses chloramine from July through March and free chlorine from April through June. If your water tastes different in spring, this is likely why.
Homes on Private Wells
Homes on private wells, such as in western Loudoun, aren't covered by public water standards. We'll recommend a purifier–softener combination based on your water test results.
These figures are system-wide data published by the agencies; actual water quality at your home may vary by water provider, season, and building plumbing. Check your local water provider's annual quality report for precise figures.

Do you install in Annandale or Centreville too?
Yes — installation is available across Fairfax County, including Annandale and Centreville, and Loudoun County, including Ashburn. For Richmond and Virginia Beach, send us your address and we'll confirm availability.
Is Northern Virginia tap water safe to drink as is?
The latest reports from Fairfax Water and Loudoun Water show tap water meeting all federal and state standards. Households usually choose a purifier for taste, disinfectant odor, or mineral content concerns.
Do I need a water softener in Northern Virginia?
Fairfax Water describes its water as moderate to hard at 5–10 gpg. If scale on kettles or shower enclosures bothers you, consider a softener alongside your purifier.
Can I install in a townhouse or apartment?
Most homes can be fitted, but renters should check with their landlord or management office first. We'll recommend the right model for your home — countertop or undersink — during your consultation.
How are filters maintained after installation?
During your rental, a Coway specialist visits every 6 months to replace filters and inspect your products. Maintenance is included in your rental fee.
