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 Hall County School District in Georgia spans 19 ZIP codes served by 30 community water systems, providing water to approximately 4,112,625 people.
The average Home Safety Score across the district is B (70/100)
- with the lowest-scoring area at 53/100 .
Water quality in this district ranks better than 52% 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
| Metric | Value | EPA Threshold |
|---|---|---|
| Average lead level (90th percentile) | 0.004 mg/L | 0.015 mg/L |
| Highest lead level | 0.014 mg/L | 0.015 mg/L |
| ZIP codes exceeding EPA action level | 0 of 19 | - |
PFAS Contamination
Detected compounds: PFOS, PFOA, PFBS, PFHxA, PFPeA.
Highest measured level: 0.0073 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 | 30.8% | Lead solder was used in plumbing until 1986 |
| Housing built before 1950 | 4.5% | Lead pipes were common before 1950 |
| Lead service line probability | 7.5% | Estimated chance of lead pipes connecting homes to water mains |
| Average lead level (90th pctl) | 0.004 mg/L | EPA action level: 0.015 mg/L |
| Highest measured lead level | 0.014 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 Hall County School District Schools?
Several factors warrant attention for families in the Hall County School District area:
- PFAS ("forever chemicals") have been detected in 4 of 19 ZIP codes. Current levels are below EPA maximums.
- 3 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
Testing
- Request your school's water testing results. Under the EPA's 3Ts program, schools are encouraged to test drinking water. Ask the Hall County School District school board for the most recent results.
- 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.
- Request lead fixture replacement if your child's school was built before 1986 and hasn't upgraded its plumbing.
- Contact your water utility about the 3 unresolved violations in the district. Ask for a timeline for resolution.

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.
- Test your home's water - Especially if your home has older plumbing (pre-1986) that may contain lead solder or lead pipes.
- 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 Hall County School District schools?
Based on EPA data, water systems serving Hall County School District have no health-based violations in the past 5 years. However, school buildings with older plumbing may still have localized issues. Testing at the tap (not just at the treatment plant) is important.
Does Hall County School District 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 Hall County School District water?
Yes, PFAS have been detected in 4 of 19 ZIP codes served by this district. 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. Reverse osmosis filters are the most effective at removing PFAS from drinking water.
