What is in the water in Amherst

Amherst is served by Erie County Water Authority .

Source water: The Niagara River, not Lake Erie. The Van de Water plant in the Town of Tonawanda takes river water and supplies northern Erie County, which is the side Amherst sits on, and it also sends water east to some Monroe County Water Authority customers through an interconnection at the Genesee County line. The authority's other plant, Sturgeon Point at Evans, draws on the lake and supplies the southern half of the county along with parts of Chautauqua and Cattaraugus. Between them they reach more than 550,000 people through 174,701 service connections. A river intake and a lake intake behave differently through the year: the Niagara responds within days to rainfall upstream, while a lake buffers the same weather over weeks, so seasonal swings in turbidity reach the northern side of the county faster. Reported by Erie County Water Authority for 2025.

Conventional coagulation, settling and filtration, finished with chlorine and a low dose of fluoride. What shapes equipment choice in Amherst is less the plant than the distance from it. This is a countywide authority serving low density suburban territory, which means long mains and slow turnover at the ends of them, and a chlorine residual that leaves the plant at a set level does not arrive everywhere at that level. Taste complaints at the far end of a suburban main are usually about a residual that has decayed and the disinfection byproducts formed along the way, not about the raw water. That is a carbon problem at the point of use, and it is worth confirming with a test at your own tap rather than reading the plant figure in the annual report.

These figures describe the distribution system. Your own tap can differ, and for lead it very likely does.

We do not yet hold a sourced figure for every field on this page. Where something is missing it is left blank rather than estimated, because an unsourced number here would look like information.

Buildings and plumbing in Amherst

The authority is identifying service line material by vacuum excavation, exposing the pipe at the curb to read both the public and the private side, then restoring the ground and leaving guidance where lead is found. Amherst has been in the investigation programme along with Aurora, Boston, Clarence, Eden, Evans, Newstead, Orchard Park and West Seneca. About 200 lead lines have been confirmed so far, but the authority projects the figure could approach 6,000 once the 12 to 15 per cent of lines presently recorded as unknown have been checked, at a cost near 75 million dollars. Amherst's advantage is its age profile: most of the township was built out well after lead pipe stopped being installed, so the probability on any given street is lower here than in the pre war city, and confirming the record for your own address is usually enough to close the question.

What this means in practice

What these figures mean for filter choice

Lead is a plumbing question rather than a supply question in Amherst, as it is everywhere. What that means practically is that a filter certified under NSF/ANSI 53 for lead at the tap you drink from sits downstream of the entire problem, whereas a whole-house filter at the point of entry sits upstream of nearly all of it and costs several times more.

Filters that apply here

  • Lead reduction filters. Point-of-use filters certified for lead under NSF/ANSI 53.
  • Under-sink carbon filters. A carbon block cartridge on the cold line under the sink.
  • Reverse osmosis, tank. A membrane system under the sink that produces treated water to a dedicated tap and stores it in a small pressure tank.
  • Whole-house filtration. A filter plumbed into the main line where water enters the building, so every tap, shower, and appliance downstream is fed treated water.
  • Sediment filters. A mechanical filter that captures sand, silt, rust flakes, and other particles.
