WHAT YOU SHOULD KNOW ABOUT BUFFALO WATER

Buffalo water meets EPA legal standards, but legal compliance is not the same as being free of health concerns. The issues flagged below are worth understanding before deciding whether to filter. EPA limits are often set below what independent scientists recommend as safe thresholds.

Lead service lines
Lake Erie algal blooms
Industrial legacy
1

Lake Erie is Buffalo's water source -- the same lake that caught fire due to pollution in 1969.

2

Harmful algal blooms in Lake Erie produce cyanotoxins that challenge water treatment.

3

Buffalo has significant lead service line infrastructure in older neighborhoods.

4

Great Lakes water quality has improved dramatically but industrial legacy contaminants remain.

COMMON QUESTIONS

Is Buffalo tap water safe to drink in 2025?

Buffalo 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 Buffalo residents are lead service lines and lake erie algal blooms. Enter your ZIP above to see the full violation history for your specific water system.

Does Buffalo water have PFAS?

EPA UCMR5 monitoring data for Buffalo (water system NY5907717) 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 Buffalo 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 Buffalo 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 Buffalo?

For Buffalo's water profile — lead service lines, lake erie algal blooms — a reverse osmosis system addresses the widest range of contaminants. Under-sink RO (Waterdrop G3P800, Aquasana SmartFlow) is the gold standard for homeowners. Renters can use a countertop RO like the Waterdrop D4 — zero installation required. Clearly Filtered pitchers are the best non-RO option for PFAS and lead.

How do I get my Buffalo 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 water utilities must publish a public inventory of their lead service lines — the pipes connecting the water main to your home. Even if your utility water tests clean at the treatment plant, lead can leach from these pipes into your tap. Homes built before 1986 are most at risk.

💡 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.
