Who this page is for

School administrators and facilities staff building a testing plan

This page is a deeper walkthrough for anyone who needs to actually run a lead testing program — every New York public school must — rather than just knowing the rule exists. It covers the legal framework, the sampling method, what the numbers mean, and what happens after a result comes back.

The law

New York’s school lead-in-water testing regulation (10 NYCRR Subpart 67-4), in plain terms

New York’s law requires testing — it is not optional. Under Public Health Law §1110 and 10 NYCRR Subpart 67-4, every public school district and BOCES must test the potable water outlets students and staff use for drinking and food preparation for lead, on a recurring cycle (generally at least every three years). There is no public-meeting alternative that substitutes for testing.

The rule first took effect in 2016 and was strengthened by amendments in 2023 that lowered the action level, expanded which outlets must be sampled, and set the recurring re-testing schedule. Federal WIIN Act funding (covered below) can offset the cost of testing and remediation.

Sampling protocol

How proper first-draw sampling works

The standard approach follows EPA's 3Ts (Training, Testing, and Taking Action) guidance for schools and child care facilities:

• Water must sit stagnant in the plumbing for at least 8-18 hours before sampling — typically achieved by sampling first thing in the morning, before any fixtures have been used since the prior evening
• The first liter drawn from each fixture ("first-draw") is collected in a dedicated sample container without running the water first
• Every fixture used for drinking or food preparation is sampled individually — a building-wide average isn't sufficient, since lead contamination is typically fixture-specific rather than building-wide
• Samples are labeled with fixture location and sent to a laboratory approved under New York’s Environmental Laboratory Approval Program (ELAP) for lead-in-drinking-water analysis

The full EPA 3Ts guidance includes a complete sampling plan template, which is worth reviewing in full before your first testing round.

Action level

Two different thresholds — don't mix them up

This is a common point of confusion, so it's worth being precise: New York's action level for school drinking water is 5 parts per billion (ppb) — lowered from 15 ppb by the 2023 amendments. Any outlet with a lead result at or above 5 ppb must be taken out of service until it is remediated, and the school must provide an alternate source of drinking water. This school-specific 5 ppb level is separate from the EPA's general 15 ppb action level, which applies to public water systems broadly under the federal Lead and Copper Rule. For a New York school, the operative number is 5 ppb, not 15 ppb.

There is no known safe level of lead exposure for children, which is part of why New York set a school action level (5 ppb) below the general federal 15 ppb figure.

Corrective action

What happens after an elevated result

Under the rule, any outlet at or above the 5 ppb action level triggers a defined response, not an ad hoc one:

• Immediate: Take the fixture out of service (shut off, bag the tap, or post a "do not drink" sign) until it's addressed
• Report: Report results to your local health department and the New York State Department of Health, and make results public; results are also shared with the State Education Department
• Investigate: Determine whether the source is the fixture itself, connecting plumbing, or a building-wide issue
• Remediate: Options range from flushing protocols and certified filters to fixture replacement or plumbing repair, depending on the cause and severity
• Re-test: Confirm the fix worked before returning the fixture to service
• Communicate: Notify staff and parents as appropriate, consistent with your district's communication plan

Funding

The voluntary testing and reduction grant program

Federal Water Infrastructure Improvements for the Nation (WIIN) Act grant funding, administered in New York through NYSDOH, helps eligible schools and child care facilities cover the cost of lead testing, training, and technical support. See the NYSDOH school lead testing program page for current eligibility and how to apply.

Recordkeeping

What to document and retain

• Sampling plan and fixture inventory used for each testing round
• Lab results, dated and tied to specific fixture locations
• Any corrective actions taken and confirmation re-test results
• Reports filed with the local health department, NYSDOH, and NYSED for each testing round
• Communications sent to staff or parents regarding results

Common mistakes

Mistakes to avoid

• Compositing samples from multiple fixtures instead of testing each one individually
• Skipping the required stagnation period, which produces artificially low results that don't reflect worst-case conditions
• Using a lab that isn't specifically accredited for lead-in-drinking-water analysis
• Leaving a flagged fixture in service while remediation is "in progress" with no defined timeline
• Assuming testing can be skipped — New York public schools must test; there is no opt-out

When to get help

When to get professional help

Consider bringing in a facility water-station service to help design a sampling plan, coordinate lab logistics, or manage remediation after an elevated result — particularly if your facilities team doesn't have bandwidth to run testing rounds on top of regular duties.

FAQ

Frequently asked questions

Is lead testing mandatory for New York schools?

Yes. Under Public Health Law §1110 and 10 NYCRR Subpart 67-4, every public school district and BOCES must test drinking-water outlets for lead on a recurring cycle (generally at least every three years). There is no opt-out.

What sample collection method should schools use?

The standard approach follows EPA's 3Ts guidance: first-draw samples collected after water has been stagnant in the plumbing for at least 8-18 hours, typically first thing in the morning before any fixtures have been used.

What lead level triggers required action in a NY school?

New York’s school action level is 5 ppb (lowered from 15 ppb in 2023). Any outlet at or above 5 ppb must be taken out of service until remediated, with an alternate drinking-water source provided and results reported to the local health department and NYSDOH. This 5 ppb school level is separate from the EPA’s general 15 ppb Lead and Copper Rule action level for public water systems.

Is funding available for school lead testing?

Yes. The NY Voluntary Lead in Child Care and School Drinking Water Testing Program, funded through the federal WIIN Act, offers eligible schools and child care facilities free testing along with training and technical support.
