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 Menifee Union School District in California spans 10 ZIP codes served by 11 community water systems, providing water to approximately 5,009,003 people.
The average Home Safety Score across the district is C (62/100)
- with the lowest-scoring area at 37/100 .
Water quality in this district falls in the bottom 61% 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.
Lead Levels in the District
| Metric | Value | EPA Threshold |
|---|---|---|
| Average lead level (90th percentile) | 0.0119 mg/L | 0.015 mg/L |
| Highest lead level | 0.022 mg/L | 0.015 mg/L EXCEEDS |
| ZIP codes exceeding EPA action level | 2 of 10 | - |
PFAS Contamination
Detected compounds: PFBA, PFPeA, PFHxS, PFBS, PFOS, PFOA, PFHxA, PFHpA.
Highest measured level: 0.025 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.

Lead Risk Assessment
Infrastructure Risk Factors
| Risk Factor | District Average | Why It Matters |
|---|---|---|
| Housing built before 1986 | 28.5% | Lead solder was used in plumbing until 1986 |
| Housing built before 1950 | 1.3% | Lead pipes were common before 1950 |
| Lead service line probability | 8.2% | Estimated chance of lead pipes connecting homes to water mains |
| Average lead level (90th pctl) | 0.0119 mg/L | EPA action level: 0.015 mg/L |
| Highest measured lead level | 0.022 mg/L | EPA action level: 0.015 mg/L |
Schools built before 1986 are especially at risk. Lead can leach from older pipes, fixtures, and solder joints into drinking water — particularly when water sits in pipes overnight or over weekends.

- 2 ZIP codes have lead levels exceeding the EPA action level of 0.015 mg/L. Lead is especially dangerous for children.
- PFAS ("forever chemicals") have been detected in 10 of 10 ZIP codes. Some PFAS levels exceed EPA maximum contaminant levels.
- 6 violations remain unresolved, meaning the issues have not been officially corrected.
Important context: EPA compliance data measures water quality at the utility level. Individual school buildings — especially older ones — may have additional risks from internal plumbing, lead fixtures, and stagnant water in pipes.
What Parents Should Do

- Test your home water. If your home was built before 1986, lead may be present in your plumbing. Free or low-cost test kits are often available from your water utility.
- Ask about PFAS testing. PFAS have been detected in this district. Request specific PFAS testing results from your water utility.
Advocacy
- Attend school board meetings and ask about the district's water quality testing schedule and remediation plans.

- 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.
- 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).
