The Problem Is More Common Than You Think

There is no safe level of lead exposure for children. The CDC, the AAP (American Academy of Pediatrics), and the EPA all agree on this point. Even low levels of lead exposure can cause irreversible harm to a child's developing brain, affecting IQ, attention, behavior, and academic performance.

Yet lead in school drinking water remains widespread. A 2018 Government Accountability Office (GAO) survey estimated that 37% of school districts that tested for lead in 2016 or 2017 found elevated levels, while 41% of districts had not tested at all. Federal law has not required schools themselves to test, and state requirements vary. Under EPA's 2024 Lead and Copper Rule Improvements, community water systems must begin sampling the elementary schools and child care facilities they serve by November 2027.

Schools built before 1986 are the highest risk. Lead solder was commonly used in plumbing until it was banned that year. Older fixtures, fountains, and pipes can leach lead into standing water, particularly when water sits in pipes overnight or over weekends.

The EPA does not set a lead limit for school drinking water: its 3Ts guidance dropped the old 20 ppb trigger in 2018 and tells schools to act on elevated results, while the 15 parts per billion (ppb) action level (dropping to 10 ppb in November 2027 under the Lead and Copper Rule Improvements) applies to water systems, not individual taps. The agency acknowledges that no level is safe. The AAP recommends a lower threshold of 1 ppb. Several states have adopted more protective standards: New York and Illinois, for example, use 5 ppb.

Step 1: Find Out If Your School Has Tested

Check public records

Some states require schools to test for lead in drinking water and publish results. Start here:

• Your state education department or health department website: Search for "[your state] school lead testing results." Many states maintain searchable databases.
• Your school district's website: Some districts publish environmental health reports, including lead testing data.
• EPA's School Lead Testing resources: The EPA provides grants and guidance to schools for lead testing under the Water Infrastructure Improvements for the Nation (WIIN) Act.

Ask the school directly

If testing data is not publicly available, you have the right to ask. Send a written request (email is fine) to the school principal or facilities manager asking:

1. Has the school tested for lead in drinking water? If so, when was the most recent test?
2. What were the results at each outlet (fountains, kitchen taps, classroom sinks)?
3. If lead was found above the action level, what remediation has been done?
4. Which testing method and laboratory were used?
5. Are results available for review?

Frame this as a collaborative inquiry, not a confrontation. Many school administrators are unaware of the issue or lack the budget to address it.

If the school has not tested

This is common, especially in states without mandatory testing requirements. You can:

• Request that the school conduct testing, citing the EPA's 3Ts program (Training, Testing, Taking Action) as a framework
• Offer to help organize parent-funded testing if the school claims budget constraints
• Contact your state health department, which may offer free or subsidized testing for schools
• Raise the issue at a school board meeting to create a public record

Step 2: Understand the Numbers

If test results are available, here is how to interpret them:

Key thresholds

• Below 1 ppb: Meets the AAP's recommended level. Minimal risk.
• 1 to 5 ppb: Detectable lead. Low risk, but worth monitoring. Some states consider this the action threshold.
• 5 to 15 ppb: Elevated. Many states and health organizations recommend remediation at this level.
• Above 15 ppb: Exceeds the 15 ppb action level EPA uses for water systems. The outlet should be taken out of service until remediated.
• Above 20 ppb: Significantly elevated. Immediate action required.

What the testing covers

Lead testing in schools typically involves collecting samples from individual outlets: drinking fountains, kitchen faucets, classroom sinks, and nurse's office taps. Results are reported per outlet, not as a building average. This matters because one fountain can test high while others in the same building test low, depending on the specific pipes and fixtures serving each outlet.

"First-draw" samples (collected from standing water in the pipes) tend to show higher lead levels than "flushed" samples (collected after running the water). Both data points are useful. First-draw results represent what a child actually encounters when they take a drink first thing in the morning.

Step 3: Protect Your Child While the School Acts

Remediation can take months or years, depending on the school's budget and the extent of plumbing replacement needed. In the meantime:

Immediate actions

• Send water from home. Fill a reusable stainless steel or glass water bottle with filtered water each morning. This is the simplest, most reliable protection.
• Filter at home. Use a pitcher or faucet filter certified to NSF 53 for lead reduction. This ensures the water you send is clean.
• Talk to your child. In age-appropriate terms, explain that it is better to drink water from their home bottle than from the school fountain. Avoid creating fear, but be clear about the preference.
• Ask about the cafeteria. If the school kitchen uses tap water for cooking and preparing meals, ask what measures are in place. Some schools have installed point-of-use filters on kitchen taps even when fountain remediation is still pending.

Flushing protocols

Some schools implement daily flushing as an interim measure: running all water outlets for 30 seconds to 2 minutes each morning before students arrive. This can reduce lead levels in first-draw water by clearing the standing water that has absorbed lead overnight.

Flushing helps but is not a permanent solution. It depends on consistent daily execution by staff, and it does not address lead that leaches during the school day from long runs of lead pipe.

Step 4: Advocate for Change

Work with other parents

Individual requests are easier for administrators to defer. A group of parents raising the same concern creates urgency. Consider:

• Forming a parent water quality committee
• Distributing a one-page summary of lead risks to other families
• Requesting a dedicated agenda item at PTA or school board meetings

Know what remediation looks like

When schools address lead in water, the typical solutions include:

• Replacing fixtures: Swapping old drinking fountains and faucets for lead-free models. Cost: $200 to $500 per fixture.
• Installing point-of-use filters: NSF 53 certified filters on individual outlets. Cost: $50 to $200 per outlet plus ongoing filter replacement.
• Pipe replacement: Replacing lead solder joints or lead pipe sections. This is the most expensive option but addresses the root cause.
• Bottle-filling stations: Replacing traditional fountains with filtered bottle-fill stations. Many newer models include built-in NSF 53 certified filters. Cost: $500 to $2,000 per unit.

Funding sources

• EPA WIIN Act grants: Provides funding for lead testing and remediation in schools and childcare facilities.
• State revolving funds: Many states allocate drinking water state revolving fund money to school water infrastructure.
• USDA funding: For schools in rural areas.
• Bond measures: Some communities have passed local bond measures specifically for school water infrastructure.

Step 5: Follow Up

Remediation without follow-up testing is incomplete. After the school takes action:

• Request post-remediation test results. Lead levels should be verified at each outlet after any fixture replacement or filter installation.
• Ask about the filter replacement schedule. Filters lose effectiveness over time. A filter installed and never replaced eventually becomes worthless.
• Request annual retesting. Lead pipes corrode over time, and new leaching can occur even after initial remediation.

Testing Your Child's Blood Lead Level

If your child has been drinking from a school outlet with elevated lead, or if you simply want baseline data, ask your pediatrician about a blood lead level (BLL) test. The CDC's reference value is 3.5 micrograms per deciliter (ug/dL). Children with levels above this threshold should receive follow-up testing and, if elevated, an investigation into the exposure source.

Blood lead testing is especially important for children under 6, whose developing brains are most vulnerable to lead's neurotoxic effects.
