About Montgomery County water

How water works in Montgomery County

Montgomery County (county seat: Fonda) mixes municipal water systems in its cities, villages, and denser towns with private wells that remain common in its more rural areas. Which setup you have — and therefore how you check your water — depends on your specific address, not just the county.

Here, systems draw from upland reservoirs (such as Hinckley), the Mohawk River corridor, and groundwater.

Your provider

Water system providers in Montgomery County

Montgomery County is served by a mix of municipal water systems, small water districts, and private wells rather than a single dominant utility. To confirm the public water system serving a specific address, check a recent water bill or use the NYSDOH and EPA lookup tools below.

Water systems (federal records)

Community water systems serving Montgomery County

Federal EPA drinking-water records list 18 active community water systems serving Montgomery County, together reported to serve about 34,518 people. The largest are shown below (by population served). Click a PWS ID for that system's federal report.

…and 3 more, mostly smaller community systems. Full federal records for every system are on EPA ECHO.

Compliance

Violations and notices in Montgomery County

Of the 18 community water systems serving Montgomery County, federal EPA records show 7 with at least one health-based violation on record over the years. A violation can range from a monitoring/reporting lapse to an exceedance that has since been resolved — open a system's federal report (linked in the table above) or its current Consumer Confidence Report for the specifics and current status.

Water characteristics

What Montgomery County water is typically like

Mohawk Valley water is generally moderate in hardness; reservoir supplies are softer while groundwater can be harder and higher in iron.

Regional patterns are a general guide only — hardness, iron, and other traits vary by specific system and well. Your CCR (or a well test) is the authoritative source for your address.

PFAS monitoring (EPA UCMR5)

PFAS testing in Montgomery County

2 water systems in Montgomery County participated in the EPA's fifth Unregulated Contaminant Monitoring Rule (UCMR5), which tested for 29 PFAS compounds and lithium in 2023–2025. In this round, no PFAS were detected above the reporting level in the Montgomery County results collected so far. See our New York drinking water standards guide for how PFAS is regulated here.

Read the fine print

What these records don't show

The system and compliance records above come from federal data. Some things people ask about are not captured here and should be confirmed directly:

• Contaminant levels at your tap. Actual values (lead, PFAS, nitrate, disinfection byproducts, etc.) come only from your system's Consumer Confidence Report or your own well test — we do not publish or estimate them.
• Water hardness. Not in the federal system records. Ask your utility for the CCR hardness value or use a home hardness test. See our hard-water guide.
• Taste, odor, color, and staining. These aesthetic issues are not standardized here; your CCR's secondary-contaminant notes and your own observations are the best guide.
• Year-over-year change. We don't track how a system's results changed from last year — compare this year's CCR to last year's using the report links.

Find your report

How to find your water provider and report

1. Check a recent water bill for your water system or district name.
2. Look up that system and its most recent Consumer Confidence Report (CCR) using the official tools below.
3. On a private well? A CCR won't apply — see our private well testing guide.

• EPA ECHO · EPA SDWIS federal reports

Confirm it's your water

Make sure a report is actually yours

1. Find the provider name and PWS ID printed on your water bill — a town name or ZIP alone is not enough to identify the system.
2. Match that PWS ID to the systems table above (or search it on EPA ECHO).
3. Open that system's current CCR for the official results and any notices.
4. For a point-of-use concern (especially lead), use a certified laboratory test for your specific tap — the system-wide report can meet standards while an individual older home does not.

Lead & older homes

Lead and service lines in Montgomery County

Lead is almost never in the water leaving a treatment plant — it typically enters from a lead service line or older home plumbing. A system-wide CCR can meet the lead action level while an individual older home shows a higher result at the tap. New York requires public water systems to inventory their lead service lines, so ask your utility for its inventory, and confirm your own tap with a certified laboratory test. See our lead & copper guide and utility report vs. home tap test.
