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 Judson Independent School District in Texas spans 12 ZIP codes served by 12 community water systems, providing water to approximately 17,034,547 people.

The average Home Safety Score across the district is A (89/100)

  • with the lowest-scoring area at 72/100 .

Water quality in this district ranks better than 89% of ZIP codes 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

PFAS Contamination

PFAS ("forever chemicals") detected in 11 of 12 ZIP codes in this district.

Detected compounds: PFBA, PFPeA, PFBS.

Highest measured level: 0.0092 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

Lead risk: ELEVATED. 5 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 38.9% Lead solder was used in plumbing until 1986
Housing built before 1950 4.4% Lead pipes were common before 1950
Lead service line probability 14.1% Estimated chance of lead pipes connecting homes to water mains
Average lead level (90th pctl) 0.0016 mg/L EPA action level: 0.015 mg/L
Highest measured lead level 0.0016 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.

Is the Water Safe at Judson Independent School District Schools?

  • PFAS ("forever chemicals") have been detected in 11 of 12 ZIP codes. Current levels are below EPA maximums.

What Parents Should Do

Testing

  1. Request your school's water testing results. Under the EPA's 3Ts program, schools are encouraged to test drinking water. Ask the Judson Independent School District school board for the most recent results.
  2. 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.
  3. Ask about PFAS testing. PFAS have been detected in this district. Request specific PFAS testing results from your water utility.

Advocacy

  1. Attend school board meetings and ask about the district's water quality testing schedule and remediation plans.
  2. Request lead fixture replacement if your child's school was built before 1986 and hasn't upgraded its plumbing.
  3. Contact your water utility about the 2 unresolved violations in the district. Ask for a timeline for resolution.

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.
