Contaminated soil remediation

Contaminated soil remediation 1. Soil washing. The soil washing process separates the colloidal fraction of contaminated soil from the inert fraction: all surface soil is, in fact, made up of a fine fraction (silt or clay) and a coarser fraction (sand or gravel), as well as organic matter, water and gas. Pollutants tend to bind (chemically and/or physically) to the colloidal fraction (silt ...
