Water Quality & Forever Chemicals
If "Arlington drinking water" brought you here, relax, no alarm bells. What follows is a plain-language roundup of what public federal water records show for Arlington, Virginia, gathered so you needn't comb through the raw datasets. The thing to hold onto: the water at your faucet is shaped by the specific utility and source tied to your address, which is why a single county-wide answer only gets you partway.

Much of the Arlington area tends to rely on treated surface water drawn from the Potomac River, a well-documented arrangement for the Washington, D.C. metro region, with raw water treated regionally before distribution. Other communities lean differently. Because your street's supply depends on the system serving it, the regional picture here is useful background rather than a guarantee about what flows from your own tap.
Around Arlington, addresses a short walk apart can be on different public water systems, so the regional view above may not describe your tap at all. The reliable way to know is to find the system listed for your address and read its annual Consumer Confidence Report, published free by every utility. One call to the utility named in the live list clears up the rest. It's genuinely worth reviewing when evaluating an address.
"Arlington water hardness" is a frequent search, and it usually traces back to spotty dishes or a crusty kettle, not to health. Potomac-fed supplies in the D.C. region tend to vary with treatment, so we won't assign your tap a number, and no dataset honestly could. The practical route: a cheap test strip, or a peek at your utility's annual report, which often lists hardness. Mystery of the filmy glassware: solved.
EPA required public water systems serving 3,300+ people to test 29 PFAS compounds between 2021 and 2024.
City-level numbers describe the broad pattern around Arlington; two homes a mile apart can sit on different water systems with very different profiles. The address report fills that gap — it identifies the public water system serving a specific property, lists any PFAS detections on that exact system, and maps the nearby industrial and Superfund sources.

We won't give you a safety verdict, and a careful reader should distrust any page that does. This page instead summarizes what federal records such as UCMR 5 show for Arlington. Note that detection differs from exceedance, and UCMR 5 mostly covers larger systems, so a quiet result means "no records here," not certified safe. Only the system serving your exact address can answer for your tap.
Look at the system or systems listed on this page, then find that utility's published contact details and its annual Consumer Confidence Report. Since adjacent addresses can sit on different public water systems, the surest approach is matching your specific address to its provider rather than assuming the county's main utility covers your home.
Broadly, much of the Arlington area tends to rely on treated surface water drawn from the Potomac River, which is well established for the Washington metro region. Your actual source depends on the system serving your address, and that utility's annual report will lay it out plainly with no guesswork.
We don't publish a hardness figure, because no dependable address-level hardness dataset exists to cite. Potomac-fed supplies vary with treatment, so generalizing further would be guessing. To learn yours, use an inexpensive test strip or check whether your utility's annual report lists hardness, as many do. It's a nuisance topic, not a health concern.
