A method to restore contaminated soil and groundwater in situ using calcium chloride |
| abstract |
(57) [Summary] [Purpose] Heavy metal pollutants are refluidized by groundwater by stabilizing soluble heavy metal pollutants existing in carbonate-containing formations or seabed using calcium chloride aqueous solution. Provide a way to prevent The method includes the step of introducing an aqueous solution of calcium chloride containing a stabilizing amount of calcium ions into the layer containing carbonate. The pollutants and carbonates inhibit the refluidization of heavy metal pollutants by groundwater by reacting with calcium ions to form coprecipitates that are poorly soluble in the fluid in the formation. |
