Is Virginia tap water safe?

For most people it clears the legal bar: VDH and EWG indicate most Virginia systems meet federal standards. The nuances are that PFAS have been detected in some communities and certain systems show disinfection byproducts above EWG's guidelines, which are stricter than the federal ones. The fastest way to see where your own water lands is your local Consumer Confidence Report, the annual quality summary your utility sends out.

Is there PFAS in Northern Virginia water?

In parts of it, yes. EWG testing found Northern Virginia tap water samples with PFAS higher than other parts of the D.C. metro area, with detections reported in the range of about 6 to 62 ppt depending on location. The wide range is the key point: it really varies by where exactly you are, so a local check beats assuming.

What are disinfection byproducts in Virginia water?

They're the trade-off that comes with disinfecting water. When chlorine reacts with natural organic matter, it forms compounds like total trihalomethanes and haloacetic acids, and EWG's Tap Water Database shows these above its health guidelines in some Virginia systems. Chlorinating the water is what keeps out bacteria, so these byproducts are a side effect worth watching rather than a sign the system is broken.

Virginia water quality

If you're in Virginia, your public system is working toward the EPA's 2024 PFAS limits, and that's the backdrop to two things worth knowing. First, PFAS (long-lasting synthetic chemicals) have turned up in several communities, and EWG testing reports notably higher levels in parts of Northern Virginia than elsewhere in the D.C. metro area, so where you live within the state matters. Second, EWG's Tap Water Database lists disinfection byproducts, the trace compounds that form when chlorine reacts with organic matter, above its own health guidelines in some systems. Neither means your tap is unsafe, but both are reasons to check what your specific utility reports.

Documented considerations

PFAS

According to EWG testing, Northern Virginia tap water samples contained PFAS at levels higher than other parts of the D.C. metro area, with detections reported up to about 62 ppt at one site; VDH tracks PFAS under EPA's 2024 rule.

Disinfection byproducts

According to EWG's Tap Water Database, some 2021-2023 Virginia samples showed total trihalomethanes and haloacetic acids exceeding EWG health guidelines, byproducts common in large chlorinated systems.

Lead

Lead in Virginia tap water comes mainly from older service lines and home plumbing; utilities are inventorying lead lines under federal rules.
