When to Test
- At the start of each school year.
- After any plumbing work, renovations, or pipe replacements.
- Whenever a waterfaucet shows discoloration, metallic taste, or rusty residue.
- When a state or local health department issues a lead advisory.
Why Lead in Drinking Water Matters
Lead is a potent neurotoxin. Children absorb it more easily than adults, and even low levels can affect brain development, behavior, and academic performance. Schools and childcare centers are where children spend most of their day, making safe drinking water a nonnegotiable priority.
The 3Ts framework**Test, Treat, Train**offers a clear, actionable path for administrators, facilities staff, and parents to protect childrens health.
1. Test: Know Whats in Your Water
How to Test
- Certified laboratories: Collect firstdraw samples (water that has been standing for at least 6 hours) from each faucet that serves drinking water. Use EPAapproved sampling bottles and follow chainofcustody procedures.
- Onsite testing kits: Useful for quick screening but must be confirmed by a certified lab for compliance.
- State programs: Many states run free or lowcost testing for schools. Contact your health department for details.
What to look for: The EPA action level for lead in drinking water is 15g/L (parts per billion). Any result at or above this level triggers remedial action.
2. Treat: Reduce Lead to Safe Levels
Immediate Controls
- Flush the tap: Run water for at least 30 seconds before drinking, especially if the water has been static for more than 6hours.
- Cold water only: Use only cold water for drinking and cooking; hot water leaches lead faster.
- Dedicated filtered water stations: Install NSFcertified pointofuse filters (e.g., undersink or faucetmount) that are rated for lead removal.
LongTerm Solutions
- Pipe replacement: Remove lead service lines and leadsoldered interior pipes. This is the most permanent remedy.
- Corrosion control: Adjust water chemistry (e.g., pH, alkalinity) through the municipal water system to reduce lead leaching.
- Wholebuilding filtration: For facilities with extensive plumbing, a centralized filtration system can treat all water before it reaches fixtures.
All treatment methods must be NSFcertified for lead reduction and should be maintained according to the manufacturers schedule.
3. Train: Build Knowledge and Sustainable Practices
Staff Training
- Provide annual workshops on watersafety procedures for custodial, maintenance, and foodservice staff.
- Cover how to collect proper water samples, interpret test results, and operate/replace filters.
- Teach emergency response if a lead advisory is issued (e.g., switching to bottled water, notifying parents).
Parent & Student Engagement
- Distribute clear, jargonfree letters explaining test results, actions taken, and what families can do at home.
- Post signage near drinking fountains highlighting Cold Water Only Flush Before Use.
- Invite parents to observe testing or filtermaintenance demonstrations.
Policy & Documentation
- Adopt a written WaterSafety Management Plan that outlines the 3Ts, responsibilities, and timelines.
- Maintain a log of all test results, maintenance records, and training attendance.
- Review and update the plan at least annually or after any incident.
Putting It All Together: A Sample Action Timeline
- JulyAugust: Review previous years watertest results and update the WaterSafety Management Plan.
- Early September: Conduct firstdraw sampling for every drinking faucet; send samples to a certified lab.
- MidSeptember: Receive results. If any location exceeds 15g/L, install pointofuse filters immediately and begin flushing protocol.
- October: Hold staff training on sample collection, flushing, and filter maintenance.
- November: Distribute a parent letter summarizing results and actions.
- January: Retest highrisk fixtures (e.g., those with elevated results).
- AprilMay: Evaluate need for pipe replacement or corrosioncontrol measures; develop budget for capital improvements.
