From industrial and coal mining area to new economic uses and cultural renaissance the role of soil remediation in the Ruhr area Prof. Dr. Wilhelm Knig, Ministry for Climate Protection, Environment, Agriculture, Conservation and Consumer Affairs, NorthRhineWestphalia, Germany Soil remediation and soil sealing conference 10.11.
remediation of this area is needed. In general, we can found microorganisms able to survive in the most extreme environmental conditions, including the soil of mining areas with high concentration of heavy metals. Different bacterial species have been characterized in areas contaminated with toxic compounds, as
Mining involves a lot of movement of soil and the surrounding area, and some ore tailings may include organic contaminants. The use of explosives and the handling and transport of ores are activities that can contribute to the issue of contaminated soil. Accidental spills are also not uncommon and can cause contamination of nearby bodies of water.
But if a person sprays certain pesticides on their yard, that could cause soil contamination. Lead is also very dangerous but occurs naturally in some soils. It was used in gasoline until 1989 and can still be found contaminating soils today. The biggest risks for soil contamination are in urban areas and former industrial sites.
Mining and smelting activities give rise to contamination of soil, air and water Thornton, 1996. This paper focuses on contamination of soil and strategies for soil remediation. Since mining activities are in areas of mineralization, there are high concentrations of certain metals and metalloids in the overlying soils in these areas Table 1.
Visit Technology Focus Area . Navy Remediation Technologies Informational webpage describes more than 40 in situ and ex situ remediation technologies for soil, groundwater, surface water, and sediment, as well as capping of wastes. Applicability, cost, duration, and limitations are discussed, and links to publications are provided.
Remediation process Soil remediation Soil remediation is known as an action of reducing the risk to human health or to the environment of a soil by treating the source of the contamination removing, treatment, containment, elimination, attenuation . Soil remediation supposes the application of techniques that can be insitu, onsite or exsitu.
Once a need for soil remediation is recognized, the best available technology is selected according to the nature, toxicity, and origin of the contaminant, the present and potential hazard related to the degree of contamination, the chemical and physical characteristics of the soil, the land use, the time available for remediation, the community acceptance, and a costbenefit analysis.
In the most polluted village of the Heshan mining area, the prevalence rate of chronic As poisoning can reach 36.5, making Heshan the nationally infamous cancer village Wang et al., 1999b. 6. Pollution control and remediation in realgar mining areas. The migration and transformation of As in realgar ores results in variable As toxicity.
Environmental remediation may also be classified as insitu or exsitu. Insitu remediation methods treat the contamination on the site without removing soil, while exsitu remediation involves excavating soil or sediment and treating it, before returning it to its original state. Environmental remediation methods
In recent decades many studies have been conducted in contaminated mining and industrial areas and in natural metalliferous soils 35,51,58,6678 in order to inventory and screen the indigenous species and evaluate their potential for phytoremediation of contaminated soils.

2. Methodology. A complete randomised design was used for the study. Soil was collected randomly from a 160m 2 area where the contaminated waste was dumped. The selected area was divided into 10 strata that were 16m 2 in size to homogenously collect samples. Ten samples of 1 kilogramme each were taken randomly from each stratum at a depth of 020cm to make one composite sample and 3
Soil Remediation in Mining Polluted Areas . of sepiolite with respect to zinc and cadmiumud was studied in order to consider their application to remediate soils polluted with these metals. The soluble metal concentrationsud as well as the readilyextractable metal concentrations were substantially decreased at any concentration of

An Analysis of Composting as an Environmental Remediation Technology 3 Finstein, 1975. The resulting compost has a high microbial diversity Beffa, 1996 and Persson, 1995, with microbial populations much higher than fertile, productive soils Table 1 and many times higher than in highly disturbed or contaminated soils. Therefore, compost
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have
The contamination factor greater than 6 indicates very high contamination as observed by Aluko et al. 10 thus the selected area was heavily contaminated. The implications of high contamination levels of heavy metals and TPHs such as alkaline, benzene, methyl benzene, and PAH in the soil as highlighted by previous studies 18, 19, cause
