Humus can form stable complexes such as chelates with polyvalent cations. SOM is capable of strong polydentate binding to transition metals in a chelate [17,19,45, 65-67]. The complexation of metal ions by SOM is extremely important in affecting the retention and mobility of metal contaminants in solid phases and waters [45]. Several different types of SOM/humus-metal reactions can occur (Fig. 11), and include reactions between DOC-metal ions, complexation reactions between SOM-metal ions, and bottom sediments-metal ions. The functional groups of SOM (Fig. 10) have different affinities for metal ions as shown below ... 

This is an ex situ anaerobic bioremediation technology for metal-contaminated soils, sludges, and sediments. While metals are the primary pollutant treated, the biological system also degrades and removes organics such as hydrocarbons. 

Fluor Daniel GTl, Inc. (now part of the IT Corporation), has developed in situ geochemical fixation technology to immobilize metallic contaminants in soil, sediment, sludge, and groundwater. The technology uses a site- and contaminant-specific combination of reagents to convert ionic contaminants to less soluble forms. In situ geochemical fixation has been used to remediate sites contaminated with chromium, uranium, molybdenum, and copper. 

Pozzolanic S/S has many varied applications in the field. It has been found to be a fast, simple, and low-cost measure for the treatment of a variety of wastes. It has been used for treating solids, liquids, sediments, and sludges from several industries, particularly those that produce heavy-metal-contaminated waste streams, and especially at sites where the soil contains lead.
