how does iron metal clean up contaminated ground water???

The use of iron in removing arsenic from water. Also, the zero-valent iron (iron metal filings) can be used to turn chlorinated solvents into harmless carbon dioxide and water.
The iron-based nanoparticles are added directly into the groundwater. When this comes into contact with water or soil contaminated with carcinogenic solvents the particles convert these hazardous chemicals into harmless hydrocarbons and chlorides often found in table salts.This method is successful with cleaning up toxic materials, heavy metals, fertilizers and pesticides in about a tenth of the time a traditional clean up would take.
We hope that clarifies your query.
