Remediation Technology

Bioremediation is a term that refers to a number of remediation technologies for treatment of both soil and groundwater using microorganisms (USEPA, 2012). Bioremediation is typically used to treat...

Soil remediation can be conducted in two ways: in-situ and ex-situ. Electrokinetic remediation can be performed as an in-situ remediation where the soil is not excavated for the purpose of decontami...

Stabilization and solidification (S/S) is a soil remediation process by which contaminants are rendered immobile through reactions with additives or processes. During this process, also called immo...

Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separa...

Soil Vapor Extraction is a common remediation technology for treating soils in the vadose zone that are contaminated with volatile compounds. In general, soil vapor extraction (SVE) consists of a sc...

Thermal desorption is a remediation method used to clean contaminated soils. This method uses heat to vaporize the contaminants, and as such only works for volatile contaminants. These include mostl...

Vitrification is the transformation of a substance into a glass. This is usually achieved by heating to high temperature and rapid cooling. In geoenvironmental engineering, soil vitrification is a me...

Sometimes grouped under the more encompassing remediation technology of “bioremediation”, phytoremediation is the process of using vegetation to break down and/or remove environmental contaminants. W...

The definition of a Permeable Reactive Barrier (PRB) by the EPA is: “An emplacement of reactive media in the subsurface designed to intercept a contaminant plume, provide a flow path through the r...

Vertical barriers or “cutoff walls” are often used in geoenvironmental engineering to control the spread of contaminants. Cutoff walls in general can either be used to directly contain a contaminant...

The United States Army has estimated that over 1.2 million tons of soil across its various facilities is currently contaminated due to explosives [1]. This contamination can be found in a variety of...

In Situ Chemical Oxidation (ISCO) is the procedure in which a chemical oxidant is introduced into the site’s subsurface with the purpose of transforming groundwater or soil pollutants into safer spe...

The use of radioactive material, specifically uranium, for the source of nuclear weapons and power spurred the movement toward exploration and mining of uranium ore in the United States. The uranium...
