What an FHA, VA, or USDA well water test actually checks in New York: the panel, the pass/fail numbers, and the validity clock

Short answer: yes. FHA, VA, and USDA loans on a New York well home all require a water test. All three point to the same rule: water quality must meet the local or state health authority’s standard, or EPA’s standard if the local authority has none. Past that shared rule, the three programs differ on the details that can trip up a closing:

• Who can collect the sample. VA and USDA both require a neutral party, not the buyer or seller. In New York, that means an ELAP-certified lab.
• How long a result stays valid. VA: 90 days from certification. USDA: no more than 180 days old at closing. FHA/HUD’s Handbook 4000.1 sets a 180-day clock for new-construction wells only; for a resale home, ask your lender what window they’ll accept.
• What “pass” means. The numbers below are regulatory limits, not a safety verdict. What a result means for your household is a question for your lender, lab, or health department — not this directory.

The one rule under all three programs

FHA, VA, and USDA don’t each publish their own contaminant list. All three point to the same chain of authority:

1. The local or state health authority decides first. VA’s Pamphlet 26-7 says water quality “must meet the requirements of the health authority having jurisdiction.” USDA’s Handbook says almost the same thing. So does HUD’s Handbook 4000.1 for FHA-insured properties.
2. EPA’s standard is the fallback, not the first rule. VA’s text continues: if the local authority has no specific requirement, EPA’s guidelines apply. USDA says the same. HUD’s Handbook points to EPA’s National Primary Drinking Water Regulations.
3. That fallback exists because private wells aren’t federally regulated at all. EPA’s own private-wells page says domestic well water “are not regulated by the Federal Government under the Safe Drinking Water Act.” USDA’s Handbook makes the same point.

New York counties often do have their own private-well standards. So the “local authority” branch usually applies — not the EPA fallback. See the county law guide linked below.

What the panel typically covers

Because all three programs route back to “local health authority, or EPA if none,” the usual tested analytes are the ones EPA and most New York counties already regulate. Treat these as regulatory limits a lab tests against — not a safety verdict:

• Total coliform bacteria. EPA does not set a simple pass/fail number here. Its Revised Total Coliform Rule sets a treatment-technique requirement instead of a numeric limit. EPA’s own summary table lists the public-system standard as no more than 5.0% of monthly samples testing positive. A mortgage well test is one sample, not monthly monitoring — ask your lab how it scores a single result. Most report it as simply present or absent.
• Nitrate and nitrite. EPA’s limit is 10 mg/L for nitrate and 1 mg/L for nitrite, both measured as nitrogen.
• Lead. EPA does not use a simple numeric limit for lead either. It’s controlled through a treatment-technique “action level” under the Lead and Copper Rule. That level has historically been 15 parts per billion. EPA’s 2024 Lead and Copper Rule Improvements lowers it ahead of a later compliance deadline, and EPA’s own pages aren’t fully consistent on the number right now. Ask your lab which figure it’s testing against.

None of the three handbooks names nitrate, nitrite, and lead as a required “panel.” What they require is the local health authority’s own list, with EPA’s analytes as the fallback. Confirm the exact required analytes with your lender and lab before you schedule. A New York county with its own private-well law may add analytes these federal handbooks don’t mention at all.

Who is allowed to collect the sample

This is the rule most likely to void a test. VA’s Handbook is direct: “All testing must be performed by a disinterested third party.” The sample can be collected by the local health authority, a commercial lab, a licensed sanitary engineer, or another party the health authority accepts. One summary of VA’s guidance puts it simply: the VA does not want the borrower, or anyone else connected to the sale, to collect the sample. USDA’s rule is the same in substance: the local health authority or a state-certified lab must do the analysis. HUD’s Handbook states the same “disinterested third party” rule for new-construction wells.

In practice, this rules out a self-collected mail-in kit for any of the three programs. In New York, that means a lab holding current ELAP certification for drinking (potable) water. Browse New York’s ELAP-certified labs to find one near the property.

The validity clock, program by program

• VA: results are valid for 90 days from the date the local health authority certifies them, unless that authority sets a different window.
• USDA: the analysis report can be no more than 180 days old at closing.
• FHA/HUD, new construction only: the report can be no more than 180 days old from the mortgage disbursement date.
• FHA/HUD, resale (existing) homes: Handbook 4000.1 does not set one universal day count here. Ask your lender directly what window they’ll accept. Don’t assume the new-construction rule above carries over.

Schedule the test early. A “fresh” result today can expire before a delayed closing.

The well-to-septic distance question

This is a separate issue from the water test itself, and buyers often mix the two up. HUD’s Handbook sets minimum distances for new construction: at least 50 feet from a septic tank and 100 feet from an absorption (drain) field. USDA’s guaranteed loan program borrows that same HUD distance standard rather than setting its own. An appraiser checks this, not your water-test lab — but a short distance can still stall a closing even if the water test itself passes.

New York specifics

Two things make a New York transaction more complicated than the federal rules alone:

1. Some New York counties add their own point-of-sale well-test law. Westchester, Suffolk, and Rockland each require a test at the sale of a home, separate from any mortgage requirement, with their own panel and their own collection rule. See the county well-water test law guide for what each county requires. You may need to satisfy both the loan program’s test and the county’s test — ask ahead of time whether one lab visit can cover both.
2. “State-certified” in New York means ELAP-certified. New York’s Wadsworth Center issues that certification per category, analyte, and method — not as one blanket stamp. Before you schedule, confirm the lab’s current ELAP scope covers the analytes your loan requires.

Find a New York lab with source-backed ELAP registry listings in Suffolk County, Ulster County, or Sullivan County. Or browse all New York drinking-water labs statewide.

What this doesn’t tell you

This guide states federal regulatory numbers and program rules as HUD, VA, USDA, and EPA write them. It does not tell you whether a specific result is safe for your household. It is not legal or financial advice. It does not confirm that any listed lab currently holds the certification, availability, or capacity your loan requires. Rules vary by lender overlay, state, and county, and federal guidance changes over time. Always confirm the current required panel and validity window with your loan officer and the lab directly before you schedule.
