      Hazardous waste: Disposal methods

      Landfills: Special landfills with stricter regulations are used for hazardous waste.
      Surface impoundments: Ponds lined with plastic and clay. Liquid hazardous waste evaporates, leaving residue.
      Deep-well injection: Hazardous waste is pumped deep underground into porous and stable rock formations, away from aquifers.
