In-situ technologies allow the soil to be treated without being excavated and transported. The primary objective of any in-situ technology focuses on the optimization of target compound mineralization while minimizing the disruption of the over-laying materials. Ideally an effective implementation of an in-silty process will address soils and groundwater beneath foundations, footings, basements, parking areas, roadways and even golf courses.

Zero Valent Iron

Zero Valent Iron, when added with other compounds to provide a source of electron donors, nutrients, and reducing agents, will stimulate naturally occurring microorganisms while oxidizing dissolved phase target compounds via the surface action of the iron particles resulting in the breakdown of chlorinated solvents.

Stabilization/Solidification

Contaminants are physically bound or enclosed within a stabilized mass (solidification), or chemical reactions are induced between the stabilizing agent and contaminants to reduce their mobility (stabilization). Stabilization/Solidification techniques can be used alone or combined with other treatment and disposal methods to yield a product or material suitable for land disposal. The contaminants targeted are generally inorganics.

Soil Vapor Extraction

Soil vapor extraction is an in-situ unsaturated zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semi-volatile contaminants for the soil. This technology is also referred to as in-situ soil venting, in-situ volatilization, enhanced volatilization, or soil vacuum extraction.
