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 2023 Government Accountability Office (GAO) report found that 41% of school districts that tested for lead found elevated levels in at least one drinking water outlet. Many schools have not tested at all because federal law does not require it in most states.

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's recommended action level for lead in school drinking water is 15 parts per billion (ppb), though 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 requires testing and remediation above 15 ppb, while Illinois and California have set standards at 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:

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:

Step 2: Understand the Numbers

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

Key thresholds

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

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:

Know what remediation looks like

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

Funding sources

Step 5: Follow Up

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

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.
