| Environmental contaminants cover U.S. grounds. These contaminants include polychlorinated biphenyls (PCBs), chlorinated organic solvents, and organochlorine pesticides<ref name="Zhang"/>. The EPA reported that more than 1500 sites are polluted and in the last decade, less than a third of them have been cleaned up<ref>[http://www.epa.gov/superfund/sites/npl/index.htm EPA (US Environmental Protection Agency), 2003a. Superfund National Priorities List (NPL).] </ref>. The current clean up procedure for these contaminants are costly and limited. Much environmental research has been dedicated to less costly alternatives<ref name="Mikszewski"/>. One alternative that has proven to be successful in laboratory research as well as field test studies is the use of nanoscale iron particles. | | Environmental contaminants cover U.S. grounds.
