Main types of contaminants, it is inevitable that many different types of contaminated land have emerged. Furthermore, there is a corresponding variability in the range of hazard that particular contaminants are considered to pose, either to the environment or public health.

Available reclamation methods,ed out (see Chapter 4). Environmental pollution is usually viewed in terms of a source and of pathways to a target at risk. Once a risk is identified, the options available are to eliminate the source, remove the target, or to cut or restrict the pathways (Figures 5.1 and 5.2). All three options are

Hazards from methane (and carbon dioxide),ominant in the early stages of material decomposition while conditions are aerobic. As conditions become anaerobic due to the gradual exclusion of air and the conversion of oxygen in the original voids, methane becomes the more dominant. In the anaerobic phase, the general range of methane and carbo

Safety in site reclamation,tract works, and also sites that have relatively low levels of contamination in the first instance. In either case the risk of encountering critical chemical hazards is frequently low, but not always so low that it can be ignored.
