Municipal and industrial wastes contribute most to soil contamination (38%), followed by the industrial/commercial sector (34%). Mineral oil and heavy metals are the main contaminants contributing around 60% to soil contamination. In terms of budget, the management of contaminated sites is estimated to cost around 6 billion Euros (€) annually ...
Much like a straw in a glass draws liquid, the pump draws liquid (including free-product) and soil gas up the tube in the same process stream. Pumping lifts LNAPLs, such as oil, off the top of the water table and from the capillary fringe (i.e., an area just above the saturated zone, where water is held in place by capillary forces).
Polycyclic aromatic hydrocarbons concentrations of soil samples taken from contaminated oil drilling cuttings in Nigeria have been decreased by 7% to 19% using white rot fungi under experimental conditions. [28] Soil contaminated with crude oil displays toxic levels of various heavy metals such as lead, zinc and magnesium.
Deep soil mixing requires specialized auger mixing equipment. In order to apply this method in-situ and in deep soil, the oxidant must be pumped to the point of mixing using a kelly bar (a piece of earth drilling equipment), or appropriate piping to the place where the soil needs to be oxidized. The soil then has to be mixed by using mixing blades.
Dredging contaminated sediment in New Bedford Harbor, Massachusetts. The harbor is contaminated with polychlorinated biphenyls (PCBs).. Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil, groundwater, sediment.

S/S technologies were used to treat a contaminated former wood treating facility in Port Newark, New Jersey. Approximately 8 acres (32,000 m 2) of soil was contaminated by wood with arsenic, chromium, and polycyclic aromatic hydrocarbons. 8% of Portland cement was used by wet weight of contaminated soil. Both in situ and ex situ processes were ...

You can find the Metadata for 1,312 European maps. This is part of the global EuDASM project making available more than 6,000 Maps from 142 countries around the World. EuDASM transferred paper-based soil maps into a digital format with the maximum possible resolution and to ensure their preservation and easy disclosure.
