Why School Water Quality Matters

Children drink 2–4× more water per pound of body weight than adults, making them more vulnerable to contaminants. School water quality affects students for hours every weekday.

Water Quality Overview

The Miami School District in Florida spans 96 ZIP codes served by 9 community water systems, providing water to approximately 228,236,160 people.

The average Home Safety Score across the district is C (59/100) — with the lowest-scoring area at 49/100 .

Water quality in this district falls in the bottom 69% nationally.

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.

PFAS Contamination

PFAS ("forever chemicals") detected in 63 of 96 ZIP codes in this district. One or more PFAS compounds exceed EPA maximum contaminant levels.

Detected compounds: 6:2 FTS, PFHxA, PFPeA, PFOS, PFBA, PFHpA, PFOA, 8:2 FTS, PFHxS, PFNA, PFBS.

Highest measured level: 0.19 µg/L.

PFAS can accumulate in the body over time. Children's higher water intake relative to body weight makes them particularly susceptible. Reverse osmosis filters (NSF/ANSI 58) are the most effective at removing PFAS.

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. Address PFAS — If PFAS are detected in your area, a reverse osmosis or activated carbon block filter rated NSF/ANSI 53 or 58 can reduce levels significantly.
  5. 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).
  6. Stay informed — Bookmark this page to check for updates on water quality in your school district.

Typical cost: Water test: typically $20–$50 (DIY kit) · Professional inspection: $150–$400

Find the Right Water Filter

Free tip: Let cold water run for 2 minutes before drinking — this helps flush lead from your pipes.

Frequently Asked Questions

Is the water safe in Miami School District schools?

Based on EPA data, water systems serving Miami School District have no health-based violations in the past 5 years. However, school buildings with older plumbing may still have localized issues. Testing at the tap (not just at the treatment plant) is important.

Does Miami School District 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).

Are there PFAS in Miami School District water?

Yes, PFAS have been detected in 63 of 96 ZIP codes served by this district. PFAS are "forever chemicals" that do not break down and can accumulate in the body. The EPA has set maximum contaminant levels for certain PFAS compounds. Reverse osmosis filters are the most effective at removing PFAS from drinking water.
