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 Las Virgenes Unified School District in California spans 9 ZIP codes served by 12 community water systems, providing water to approximately 8,239,901 people.

The average Home Safety Score across the district is C (57/100)

  • with the lowest-scoring area at 40/100 .

Water quality in this district falls in the bottom 74% 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 Risk Assessment

Lead risk: ELEVATED. 7 ZIP codes in this district have high lead exposure risk scores based on housing age and infrastructure.

Infrastructure Risk Factors

Risk Factor District Average Why It Matters
Housing built before 1986 70.9% Lead solder was used in plumbing until 1986
Housing built before 1950 5.4% Lead pipes were common before 1950
Lead service line probability 21.9% Estimated chance of lead pipes connecting homes to water mains
Average lead level (90th pctl) 0.0036 mg/L EPA action level: 0.015 mg/L
Highest measured lead level 0.0053 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.
