What are treatments for arsenic removal for private drinking water wells?

  • Reverse osmosis: cost-effective method but produces 2-3 gallons daily
  • Anionic exchange system: little maintenance and treats the entire house but the treated water can have a low pH, high levels of chloride, and if the system fails all of the captured arsenic can be released at once
  • Iron oxide filter systems: can be used as point if entry systems and they are disposable as non-hazardous waste but they must be replaced on a regular basis
  • Switch drinking water sources
