The present invention provides a process for enhancing the metal contaminant sorption capacity of mineral compounds within a groundwater-bearing formation by manipulating the pH and the surface acidity of the mineral compounds. The process is useful in removing metal contaminants from groundwater within a groundwater-bearing formation, providing a backstop treatment for groundwater after previous water treatment, and for protection of water sources, for example well-head protection.
L'invention concerne un procédé permettant d'améliorer la capacité de sorption de contaminant métallique de composés minéraux dans une formation qui contient des eaux souterraines par manipulation du pH et de l'acidité de surface de composés minéraux. On utilise ce procédé pour supprimer les contaminants métalliques des eaux souterraines d'une formation, pour effectuer un traitement de dernier recours après un traitement antérieur de l'eau et pour protéger les sources d'eau, par exemple, une tête de puits.
