Abstract: Methods of decreasing the amount of one or more contaminants in contaminated soil comprise introducing polymer-coated nanoparticles into the contaminated soil, optionally with other reagents. The polymer-coated nanoparticles exhibit an enhanced ability to migrate through the soil and provide greater control of the rate of activation of other chemicals, such as oxidants, in the contaminated soil.
