Why Did a Letter Come Home About Water Testing?
Publication boundary: This is an independent educational guide. It does not test water, interpret a specific result, allege a safety violation, or speak for any school, water utility, or agency.
Some schools test drinking water fountains and faucets for lead, a metal that can affect a child’s development, because school plumbing can add lead even when the water arriving from the utility meets health standards. When a family gets a short notice about testing, the first useful question is not what a result means, but where to find it and how to ask.
Are Schools Required to Test Drinking Water for Lead?
There is no single federal law requiring every school to test its own drinking water for lead, except schools that own their water supply. Most public water suppliers test water at homes, not inside school buildings, which is why the U.S. Environmental Protection Agency (EPA) publishes voluntary guidance schools can use on their own.
That guidance is organized around three steps EPA calls the “3Ts”: Training staff to understand the issue, Testing water at outlets like fountains and faucets, and Telling students, parents, staff, and the community about results and next steps. Telling is where most family confusion starts, because a testing program can run well and still communicate its results poorly.
What Should Clear Communication About Results Include?
EPA’s communication guidance for the 3Ts program describes what a complete update should include: the current status of testing, the actual results, and any plan to correct a problem. It also recommends one point of contact, more than one method of reaching families, such as letters, a website page, or a newsletter, and updates at set points rather than a single announcement.
In practice, that means a family should be able to point to specific information rather than a general reassurance. For everyday building conditions beyond water testing, our healthy school environments questions guide covers how to turn an observation into a routed question.
What Questions Can Families Ask at Each Stage of Testing?
Communication about school water testing happens in stages. Asking one focused question at the right stage works better than one broad question like “is the water safe.”
Stage 1: Before or at the start of testing
- Is our school currently part of a lead-in-drinking-water testing program, and who is coordinating it?
- Which buildings and which types of outlets (drinking fountains, kitchen sinks, classroom sinks) are included?
- Where will results be posted or shared once they are available?
Stage 2: After results come back
- Where can I see the actual results, not just a summary statement?
- What date were the samples collected, and from which specific outlets?
- What level does the school’s guidance use to decide an outlet needs follow-up, and is that level shown next to the results?
Stage 3: If an outlet needs follow-up
- Was the outlet taken out of service, and how will affected families be told which one?
- What is the plan and timeline for retesting or fixing it?
- Who is the point of contact for questions about that specific outlet?
Stage 4: Ongoing updates
- How often will testing and results be reviewed?
- Where is the most current information kept, so I’m not relying on an old letter?
- Who do I contact if I haven’t seen an update in a while?
What if I Can’t Find the Information I’m Looking For?
This guide helps a family locate and ask about information. It does not tell you whether a specific number is a health concern or whether a school has broken a rule; neither test results nor this guide replace advice from a qualified health provider. If you have a concern about a child’s possible lead exposure, a pediatrician or local health department can discuss blood lead testing. For an unrelated medical emergency, contact local emergency services directly rather than routing it through a newsletter or website.
When information is missing or unclear, a short decision path helps:
- No information at all is available. Ask the school’s stated point of contact whether a testing program exists and where updates are posted.
- A general statement exists, but not actual results or dates. Ask specifically for the sampling date, the outlets tested, and the numeric results.
- Results are posted, but a follow-up plan is unclear. Ask what the next step is, who owns it, and when it will be reviewed again.
- The answer still isn’t clear after asking directly. Note the date you asked and who you asked, and follow up in writing so there’s a record.
For help identifying which staff role should own a specific question like this, see our family, school, and community coordination guide.
How Should a Family Keep Their Own Record?
A short written record helps track a request without turning it into a public accusation. Useful items to note: the date of the notice you received, the specific question you asked and to whom, the date you asked and any response date, and what was answered versus what’s still unclear. Keep private details, such as a child’s name or health information, out of general emails, public posts, and this publication’s Contact form.
Frequently Asked Questions
Does federal law require schools to test drinking water for lead?
No single federal law requires it for schools served by a public water system. The exception is schools that own and operate their own water supply, which are regulated under the Safe Drinking Water Act. Many states set their own additional requirements.
What are the “3Ts” schools use for lead in drinking water?
Training, Testing, and Telling. Training prepares staff to understand the issue, Testing samples water at outlets like fountains and faucets, and Telling communicates results and next steps to students, parents, staff, and the community.
Where should a school share its water test results?
EPA’s guidance recommends more than one method, such as letters or fliers home, a website page, a staff or parent newsletter, or presentations at PTA or school board meetings, with one named point of contact for questions.
What should I do if I can’t find my school’s water test results?
Ask the school’s stated point of contact whether a testing program exists and where updates are posted, then ask for the specific sampling date, outlets tested, and numeric results rather than a general summary.
