Serving 155K residents via Alexandria Renew Enterprises / UOSA · Alexandria, VA drinking water is supplied by Alexandria Renew Enterprises / UOSA. EPA and public water system monitoring commonly focus on issues such as Lead from older infrastructure, Potomac River contamination, Disinfection byproducts. Neighborhood water age varies with dead-end mains, fire-flow loops, and construction-related reroutes—small changes that can nudge taste, color, and DBP numbers at the tap. Use the ZIP tool to align this overview with the contaminant list and violation history for the exact PWSID serving your meter.

WHAT YOU SHOULD KNOW ABOUT ALEXANDRIA WATER

Alexandria water currently shows no major violations in EPA monitoring data. That said, your home's internal plumbing can add lead or other contaminants after water leaves the treatment plant — especially in homes built before 1986.

LEGAL DOES NOT ALWAYS MEAN SAFE

Alexandriawater may meet federal EPA limits while still showing contaminants above independent health guidelines (EWG, state advisories). EPA MCLs are often set on treatment feasibility — not a "zero risk" threshold. Compare levels below to health guidelines and state/U.S. utility averages, then see which filter technologies address your profile.

COMMON QUESTIONS

Is Alexandria tap water safe to drink in 2026?

Alexandria water meets EPA legal standards, but meeting legal standards is not the same as being free of health concerns. EPA limits are set based on treatment feasibility, not always on what independent scientists consider safe. The main concerns for Alexandria residents are lead from older infrastructure and potomac river contamination. Enter your ZIP above to see the full violation history for your specific water system.

Does Alexandria water have PFAS?

EPA UCMR5 monitoring data for Alexandria (water system VA6510010) is shown above. PFAS — sometimes called "forever chemicals" — are synthetic compounds that don't break down in the body. Only reverse osmosis systems or NSF 58-certified carbon block filters reliably remove PFAS from tap water. Standard pitcher filters do not remove PFAS.

Does Alexandria water have lead?

Lead in tap water almost always comes from the pipes inside your home or building, not the treatment plant. Homes built before 1986 in Alexandria are most at risk because they may have lead solder, brass fittings, or lead service lines. The EPA has no safe level for lead in children. An NSF/ANSI 53-certified filter or reverse osmosis system removes lead at the tap.

What water filter is best for Alexandria?

For Alexandria's water profile — lead from older infrastructure, potomac river contamination — a reverse osmosis system addresses the widest range of contaminants. Under-sink RO (Waterdrop G3P600, Aquasana SmartFlow) is the gold standard for homeowners. Renters can use a countertop RO like the Waterdrop K19-S Countertop RO — zero installation required. Clearly Filtered pitchers are the best non-RO option for PFAS and lead.

How do I get my Alexandria water tested?

For the most accurate results for your specific tap, use a certified mail-in lab test rather than relying on city-wide data. SimpleLab Tap Score tests for 100+ contaminants including PFAS, lead, arsenic, and nitrates. Results come with a detailed health assessment and filter recommendations. City-wide EPA data like what you see above is a strong baseline, but your home's plumbing can add contaminants after the water leaves the treatment plant.

LEAD SERVICE LINE RISK
Does your street have lead pipes?

As of October 2024, all US public water systems must publish a public inventory of their lead service lines — the pipes connecting the water main to your home. Even if your public water system water tests clean at the treatment plant, lead can leach from these pipes into your tap. Homes built before 1986 are most at risk.

EPA Official Service Line Inventory →
Federal LCRR inventory data for Alexandria Renew Enterprises / UOSA · PWSID VA6510010
💡 Homes built before 1986 may have lead solder or service lines. A filter certified NSF/ANSI 53 removes lead at the tap regardless of pipe material.
