1.Diels proposed the use of sludge reactors for non-saturated soils, using sulfate reducing bacteria SRB, as well as in situ heavy metals immobilization using SRB as well.
2.Other methods reported include hot water soil washing which could be followed by hydrogen peroxide oxidation for Cr(VI) treatment. Many methods consist in the extraction of metals from soils using soil washing, followed by techniques developed for water or wastewater systems, such as the following£¨SW). SW plus metal adsorption onto activated carbon , SW plus metal adsorption by calcium alginate beads , SW followed by metal precipitation  and SW and Cr(VI) reduction using an adsorbent prepared from rice husk
3.Very frequently, surfactant enhanced soil washing SESW pro-jects are carried out using model soils, i.e. pristine soils contami-nated artificially with metals. It happens also in works where the
aim is the cleaning up of soils contaminated with organic com-pounds (oil fractions, pesticides, phenols, PCB¡®s, antibiotics, etc.The situation is more complicated in the case of the metals, since metals are natural soils components and they can be desorbed from soils, by changing the pH. In general, it is well known that
metals are more free at low pH values, whilst at basic conditions
metals are less ionized, and so, less available.
