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.
Home Safety and Water Evidence Overview
The Thompson School District R-2J in Colorado spans 13 ZIP codes. This materialization has canonical Home Safety Scores for 11 ZIP records and typed EPA water violation counts for 13 ZIP records. Missing evidence is not treated as zero.
The deduplicated primary-system served-population sum is 527,406 across 10 water systems. This is not the district resident population.
The average Home Safety Score under model 4.0.0 across 11 scored ZIP records is D (46/100)
- with the lowest-scoring area at 31/100 .
Water quality in this district falls in the bottom 76% 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) | 0.0078 mg/L | 0.015 mg/L |
| Highest lead level | 0.015 mg/L | 0.015 mg/L |
| ZIP records exceeding EPA action level | 0 of 13 with known status | - |
PFAS Contamination
Detected compounds: PFOA.
Highest measured level: 0.0048 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
- 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.
- Review the Consumer Confidence Report (CCR) - Your water utility publishes this annually. It details all detected contaminants.
- Consider a water filter for your home - NSF/ANSI 53 or NSF/ANSI 58 (reverse osmosis) filters are certified to remove lead. This is especially important for infant formula preparation.
- 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).
- Stay informed - Bookmark this page to check for updates on water quality in your school district.

Frequently Asked Questions
Is the water safe in Thompson School District R-2J schools?
EPA system-level records associated with Thompson School District R-2J show 64 health-based violations across 13 ZIP records with known health counts. These records do not measure individual school taps. Parents should request current building-level testing results from the school district.
Does Thompson School District R-2J 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 Thompson School District R-2J water?
Yes, PFAS have been detected in 7 ZIP records associated with this district. ZIP records without PFAS evidence are not counted as tested negatives. 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.
