Contaminated soils that require off site disposal are required to be classified in accordance with the NSW DECC Waste Classification Guidelines. Based upon chemical analysis, soils are classified within one of the following six categories. General Solid Waste (Putrescible) Contaminated waste material that does not exceed specific contaminant concentrations (SCC) and leachable concentration (TCLP) concentrations [...] Underground Storage Tanks (USTs) are often found associated with industrial processes. They often contain diesel, unleaded petrol, leaded petrol, heating oil, kerosine, aviation fuel and waste [...] Capping a contaminated site is a relatively low budget means of containing the contaminants onsite. Capping materials can be both natural and synthetic and the complexity of the systems that they are used are dependent upon numerous [...] Landfarming is a bioremediation technique. Contaminated soils, sediments and sludges can be spread on the ground and periodically tilled to aerate and encourage bacterial growth. Contaminants are degraded, transformed, and immobilized by microbiological processes and by [...] Cement stabilisation is a remedial treatment technology used for contaminated soils. It results in the encapsulation of contaminants, an increase in compressive strength and a decrease in the permeability of contaminated [...] |
