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

  1. 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.
  2. Review the Consumer Confidence Report (CCR) - Your water utility publishes this annually. It details all detected contaminants.
  3. Test your home's water - Especially if your home has older plumbing (pre-1986) that may contain lead solder or lead pipes.
  4. 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).
  5. Stay informed - Bookmark this page to check for updates on water quality in your school district.

No lead action-level exceedance is recorded among 12 ZIP records with known status. This does not establish safety at an individual school tap; request current building-level testing results.

Does Langford School District 45-5 test for lead in school water?

Federal law does not require schools to test for lead in drinking water (except in some states with specific mandates). The EPA's voluntary 3Ts program encourages testing. Contact your school district office to ask about their testing schedule and results.

What level of lead is safe for children?

There is no safe level of lead for children, according to the CDC. The EPA action level of 0.015 mg/L (15 ppb) triggers corrective action for water systems, but the American Academy of Pediatrics recommends that school water contain no more than 0.001 mg/L (1 ppb).
