What shows up most in Florida tap water

  • Disinfection byproducts (trihalomethanes and haloacetic acids): form when chlorine meets organic matter. Florida's warm, organic-rich source water makes them common statewide.
  • Arsenic: occurs naturally in parts of the Floridan aquifer.
  • Sulfur (hydrogen sulfide): the rotten-egg smell common in Florida well and groundwater.
  • PFAS "forever chemicals": detected in some South Florida systems.
