Water Filtration and Treatment in Amherst, NY
Amherst is on Erie County Water Authority supply drawn from the Niagara River, which is a different plant and a different source from the city next door. On the numbers homeowners notice most, it reads higher. Water Filtration Buffalo installs filtration and treatment systems for Amherst homes sized to ECWA’s published figures, not to Buffalo’s.
What Is Actually In Amherst Tap Water
The ECWA Amherst system serves about 92,700 people from the Van de Water plant in Tonawanda, which draws from the Niagara River. ECWA reported no violations in 2025. The water is safe. It also carries nearly twice the chlorine Buffalo does, a higher lead reading, and detectable PFAS, all of which are inside the legal limits and all of which are worth knowing before you choose a system.
ECWA distribution system, ranging 0.82 to 1.80 ppm. Buffalo Water averages 0.86.
Against a 15 ppb action level, with one sample at 11.2 ppb. Buffalo’s figure was 2.8.
Trihalomethanes ranged 15.7 to 66.1 ppb across ECWA sites. The running average stayed under the 80 ppb limit.
Both measured at about 2.6 parts per trillion against a 10 ng/L limit. Detected, compliant, and filterable.
Figures are from the Erie County Water Authority’s 2025 annual water quality report, PWS ID NY1400443 and NY1400399 for the Amherst system. All results were within legal limits. ECWA does not publish a hardness figure, so we measure it at your tap rather than assume Buffalo’s number applies.
A Different River, a Higher Chlorine Dose, and Post-War Plumbing
The New York State source water assessment rates the Niagara River source as having elevated susceptibility to contamination, citing agricultural runoff, a high density of wastewater discharges, and industrial sites upstream. Lake Erie, which supplies Buffalo, is rated moderate. Treatment at Van de Water handles it, but the chlorine dose needed to keep that water safe across the northern suburbs averages 1.62 ppm, and that is what you smell in the shower in Snyder or Eggertsville.
Amherst housing runs from 1920s and 1930s homes in Eggertsville and Snyder through the post-war ranches and 1970s to 1990s subdivisions of East Amherst and Getzville. The older streets can have galvanized service lines and copper with lead solder, which is the likely reason ECWA’s lead reading runs higher than Buffalo’s despite a newer housing stock overall.
- Chlorine taste and smell noticeably stronger than in the city
- Lead readings that run higher than Buffalo's, driven by older plumbing in Snyder and Eggertsville
- Trihalomethane readings up to 66 ppb at some ECWA sampling sites
- PFOA and PFOS present at low, compliant levels
- Scale on fixtures, with a hardness figure ECWA does not publish
Systems Sized for ECWA Water
At 1.62 ppm chlorine, carbon capacity is sized larger than it would be for the same house in Buffalo. Reverse osmosis is the answer for anyone who wants PFAS and lead handled at the kitchen tap.
Carbon Filtration, Sized Up
Nearly double the chlorine means a larger carbon bed or more frequent media changes. We size to ECWA's number, not the regional average.
Reverse Osmosis
Reduces PFOA, PFOS, lead, and dissolved solids at the kitchen sink. The right choice for drinking and cooking water on Niagara River supply.
Water Softener
Sized to the hardness we measure at your tap, since ECWA does not report it and it varies across the system.
Systems we install here: whole-home filtration, water softeners, carbon filtration, reverse osmosis, city water treatment, and well water treatment.
How We Work in Amherst
We confirm your supply, test at your tap, and size to the ECWA numbers rather than assuming Amherst water is the same as Buffalo’s.
Confirm ECWA and Test
We verify you are on the ECWA Amherst system, then measure chlorine and hardness at your tap and test for lead if the house predates the 1980s.
Size to the Real Numbers
Carbon capacity, softener grain size, and whether RO is warranted all follow from what your tap shows, not the citywide average.
Install After the Meter
We install on the main line, commission the system, and give you a maintenance schedule in writing.

Frequently Asked Questions About Water Filtration in Amherst, NY
What Amherst homeowners ask most often.
Yes, in source and in treatment. Buffalo Water treats Lake Erie water at the Colonel Ward plant. Amherst gets Niagara River water from ECWA’s Van de Water plant in Tonawanda. ECWA runs chlorine at an average of 1.62 ppm against Buffalo’s 0.86, and its lead reading at the 90th percentile was 6.47 ppb against Buffalo’s 2.8. Both are compliant. A system sized for one is not automatically right for the other.
Because there is nearly twice as much of it. ECWA’s distribution average is 1.62 ppm and ranged as high as 1.80 in 2025. That dose is what keeps Niagara River water safe across the northern suburbs, and it is also why whole-home carbon filtration in Amherst needs more capacity than the same system in Buffalo.
ECWA reported PFOA at 2.62 and PFOS at 2.61 nanograms per liter, both about a quarter of New York’s 10 ng/L limit. That is a detection, not a violation. If you would rather not have it in your drinking water at any level, reverse osmosis at the kitchen sink is the practical answer, and it handles lead and dissolved solids at the same time.
Higher than a 1990s house in East Amherst. Pre-1986 plumbing can have lead solder, and older streets can have galvanized service lines that accumulate lead. ECWA’s own 90th percentile reading was 6.47 ppb with a single sample at 11.2. A first-draw tap test tells you where your house stands, and treatment follows from the result.
It matters for what you plan around. The state rates the Niagara River source as elevated susceptibility because of upstream wastewater discharges, agriculture, and industrial sites. Van de Water’s treatment handles it, which is why the finished water is compliant, but the higher chlorine dose and the byproducts that come with it are what a carbon system in Amherst is sized for.
If your address is in the Town of Amherst, you are on the ECWA Amherst system, PWS ID NY1400399, which ECWA operates on behalf of the town. Your bill comes from ECWA either way. The water, the plant, and the numbers are the same. It only matters for reading the right line in the annual report.
