Why This Matters for Children
Children are more vulnerable to water contaminants than adults. The EPA and CDC identify these key risks:
- Lead exposure — Even low levels of lead can affect brain development, reduce IQ, and cause behavioral problems in children. There is no safe level of lead for children.
- PFAS ("forever chemicals") — Linked to immune system effects and developmental delays in children. Children drink more water relative to body weight than adults.
- Nitrate — Dangerous for infants (can cause "blue baby syndrome"). Agricultural areas often have elevated nitrate.
- Disinfection byproducts — Long-term exposure may increase cancer risk. School water fountains often have stagnant water that concentrates these compounds.

What Parents Can Do
- Request lead testing at your child's school — The EPA's 3Ts program (Training, Testing, Taking Action) provides guidance for schools. Ask your school board about their water testing schedule.
- Review the Consumer Confidence Report (CCR) — Your water utility publishes this annually. It details all detected contaminants.
- Test your home's water — Especially if your home has older plumbing (pre-1986) that may contain lead solder or lead pipes.
- Pack water from home — If you're concerned about school water quality, send your child with a water bottle filled at home (filtered if possible).
- Stay informed — Bookmark this page to check for updates on water quality in your school district.
