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.
The Philippine Council for Agriculture, Aquatic, and Natural Resources Research and Development (PCAARRD) is a council of the Department of Science and Technology of the Philippines government. The council aims to help national research and development efforts in agriculture, forestry, and natural resources of the Philippines. It does so by ...
This method disperses contaminated soil and aerates the soil by cyclically rotating. [30] This process is an above land application and contaminated soils are required to be shallow in order for microbial activity to be stimulated. However, if the contamination is deeper than 5 feet, then the soil is required to be excavated to above ground. [13]
The Philippines' Bureau of Soils and Water Management (Filipino: Kawanihan ng Pamamahala sa Lupa at Tubig, [1] abbreviated as BSWM), is an agency of the Philippine government under the Department of Agriculture responsible for advising and rendering assistance on matters relative to the utilization of soils and water as vital agricultural resources.
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless".

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. [1]
ISCR is usually applied in the environment by injecting chemically reductive additives in liquid form into the contaminated area or placing a solid medium of chemical reductants in the path of a contaminant plume. [1] It can be used to remediate a variety of organic compounds, including some that are resistant to natural degradation.
