Bill Summary · HB 2640

Legislative bill overview

HB 2640 would prohibit the use of fertilizers containing PFAS (per- and polyfluoroalkyl substances) in Arizona. The bill appears designed to restrict these "forever chemicals" from entering the state's soil and water systems through agricultural and landscaping applications.

Why is this important

PFAS chemicals persist indefinitely in the environment and accumulate in human blood, with emerging evidence linking them to health issues including liver damage, immune suppression, and developmental effects. Fertilizers containing PFAS-based biosolids (treated sewage sludge) represent a significant pathway for these chemicals to enter food crops and groundwater, making this a public health and environmental concern.

Potential points of contention

  • Agricultural/industry costs: Fertilizer manufacturers and farmers may face increased compliance expenses if reformulation is required, potentially raising input costs and food prices
  • Enforcement challenges: Determining PFAS content in fertilizers requires testing infrastructure; the bill's enforcement mechanism and who bears testing costs remain unclear
  • Biosolids management: If the bill restricts PFAS-containing biosolids, it may shift waste disposal problems elsewhere or increase wastewater treatment costs for municipalities
