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.
