Virginia sits in the moderate tier of the country’s PFAS landscape — the chemicals are present, but the state has not become a household name in the way a handful of hotspot states have. What sources are documented lean heavily toward the military side of the ledger, with aqueous film-forming foam (AFFF) sites tied to the state’s substantial defense footprint, alongside a scattering of industrial detections emerging chiefly through the EPA’s UCMR 5 monitoring. Without a single dominant, nationally recognized drinking-water case to anchor Virginia’s story, the most honest advice doubles as the most useful: the only way to learn whether PFAS are in your particular supply is to test it, and that is true whether your water arrives from a city main or a well in the yard.

The “forever chemical” label captures how doggedly PFAS resist breaking down, which is exactly what lets them accumulate in water sources and in the human body over the long run. In 2024 the EPA finalized its first enforceable federal drinking-water limits, closing a gap that had persisted for years. PFOA and PFOS were each held to 4 parts per trillion. PFNA, PFHxS, and the GenX chemicals were assigned a 10 ppt ceiling, and a hazard-index rule now governs certain combinations of these compounds. As of 2026 Virginia has not adopted a stricter enforceable state MCL of its own, so the federal EPA standard is the one that applies across the commonwealth.

If a test brings PFAS to light, three treatment technologies have earned the strongest reputations. Granular activated carbon draws PFAS out of water by adsorption and slots naturally into whole-house systems. A strong-base anion exchange resin attracts charged PFAS molecules and frequently handles shorter-chain compounds better than carbon working alone. Reverse osmosis forces water through a fine membrane to deliver very high reduction at a single dedicated faucet.

The choice between whole-house and point-of-use hinges on how broadly you want the protection to extend. A whole-house carbon or anion system treats every tap and shower in the home, whereas an under-sink reverse osmosis unit narrows its focus to the water you drink and cook with, at a lower cost. Many Virginia homeowners — especially those living near AFFF-linked installations — run both together. In all cases the sequence stays constant: begin with a laboratory accredited for PFAS analysis, and retest after any system is installed to confirm it is doing its job.

Let your water source shape your testing approach. On a municipal supply, the utility’s Consumer Confidence Report and its UCMR 5 sampling offer an opening snapshot, though they reflect only certain compounds captured at certain times. Virginia also has a large number of households on private wells, particularly beyond the larger metro areas, and those wells receive no public monitoring whatsoever — making an independent certified test the only reliable measure. Once equipment is installed, plan for maintenance from the start: activated carbon and anion resin hold a finite capacity and eventually reach breakthrough, while RO membranes and prefilters wear out and need replacement. Combining scheduled media changes with periodic retesting keeps a PFAS system reducing contaminants effectively over the years. Given how much of Virginia’s documented PFAS activity traces to AFFF and defense-related sites, households near current or former installations have particular reason to run a baseline test rather than assume distance alone offers protection; groundwater can carry these compounds well beyond a facility’s fence line. A single early result establishes where you stand and makes any future change easy to spot.

No alarm is needed here — test your water, review the numbers, and let them guide which system makes sense for your home.
