Health Effects of PFAS

  • Increased risk of kidney and testicular cancer
  • Thyroid disease and immune system suppression
  • Reproductive problems and reduced fertility
  • Elevated cholesterol and liver effects
  • Developmental effects in infants and children

Health risk severity: High. Governed by the PFAS National Primary Drinking Water Regulation (2024).

How PFAS Gets Into Drinking Water

  • Firefighting foam (AFFF) used at military bases and airports
  • Industrial manufacturing (non-stick coatings, stain-resistant fabrics)
  • Wastewater treatment plants that receive industrial discharge
  • Landfill leachate from PFAS-containing consumer products

What to Do About PFAS in Philadelphia Water

  1. Install a reverse osmosis system (most effective — removes 90%+ of PFAS)
  2. Granular activated carbon (GAC) filters remove some PFAS compounds
  3. Look for NSF 53 or NSF 58 certification specifically tested for PFAS
  4. Pitcher filters with activated carbon provide partial reduction

Look for filters certified under NSF 53 / NSF 58 for pfas removal.
