Objective:
Progress Summary:
The widespread occurrence of dense non-aqueous phase liquids (DNAPLs) such as the chlorinated hydrocarbons in groundwater and in soil is of serious environmental concern. These contaminants transport rapidly in the subsurface to create a contaminant plume as a result of vertical migration due to their higher density than water. In recent years, the use of zero-valent iron nanoparticles has represented a promising and innovative approach to the destruction of these compounds. But iron nanoparticles aggregate and it is very difficult to deliver these nanoparticles to the site of decontamination.
