PFAS (Per- and Polyfluoroalkyl Substances) are harmful chemicals that pose significant health risks when present in drinking water. Understanding how to effectively remove them is essential for ensuring safe, clean water in your home or office.

What Are PFAS?

• Common Sources: Found in everyday products including:
  • Nonstick cookware
  • Water-resistant clothing
  • Firefighting foam
  • Cosmetics
  • Food packaging (e.g., pizza boxes, popcorn bags)
• "Forever Chemicals": They don't break down naturally in the environment, leading to long-term exposure risks.
• Health Risks: Linked to liver damage, cancer, and weakened immune systems with prolonged exposure.

PFAS in Singapore's Drinking Water

• Regular Monitoring: PUB (Public Utilities Board) has tracked PFAS levels since 2016.
• Safe Levels: Current PFAS concentrations remain below U.S. EPA safety limits.

Effective PFAS Removal Methods

• Granular Activated Carbon (GAC) Filtration:
  • Adsorbs PFAS molecules from water
  • Cost-effective solution for both municipal and home systems
• UVC Light Treatment:
  • Breaks down PFAS by disrupting chemical bonds
  • Most effective when combined with GAC filtration

Why Focus on PFOA and PFOS?

• These specific PFAS compounds were phased out but remain persistent in the environment
• Their removal is critical for preventing long-term health and environmental impacts

Conclusion

While PFAS contamination presents serious challenges, modern filtration technologies like GAC and UVC light can effectively remove these harmful chemicals from your drinking water. By implementing the right water treatment solutions, you can protect your health and ensure access to clean, safe water.
