COLLOIDAL AGENTS FOR AQUIFER AND METALS REMEDIATION

摘要

Compositions and methods for treating contaminated soil and/or ground water in situ. The compositions and methods comprise stabilized forms of colloidal remediation agents that are used to remediate contaminants, namely, organic and inorganic contaminants. The compositions and methods of the present invention are operative to transport particulate remediation agent materials through a matrix of soil and groundwater upon application by injection, gravity feed, or percolation into soil and groundwater, which in turn sequester, destroy or stabilize contaminants out of water to thus decontaminate groundwater in place without the cost or disruption associated with digging the contaminated soil and groundwater out of the ground for on-site purification or disposal at a hazardous waste landfill.
