Getting Rid of FOREIGN OIL overruns by overdosing a site, hence wasting resources. Environmental remediation injection technologies fundamentally promote either abiotic chemical reactions, biologically mediated reactions, or a combination of the two. Following are descriptions of several chemical and biological injectates and technologies. “ Sites involved with real estate property transactions, third-party liability concerns, or associated with sensitive receptors are especially good candidates for injectionbased remediation.

Chemical injectates Chemical oxidation: Chemical oxidation is defined as an abiotic reaction where electrons are transferred from electron donors to electron acceptors, and in the process the constituents of concern (COCs) undergo transformation to less harmful end products. Often, a variety of reactions will occur, sometimes with the intermediary products having equal or worse toxicity than the original COC. Generally, end products are CO2 gas and water. Various oxidants can be used to perform the reactions, with most utilizing the formation of a species called a free ” radical. Free radicals, or simply radicals, are unstable species that are highly reactive, which give this technology the ability to degrade a variety of organic chemicals quickly. Typical oxidants are permanganate, persulfate, hydrogen peroxide/Fenton’s reagent and ozone. Many proprietary oxidants are also available. Reductive dechlorination: As with biotic reductive dechlorination, abiotic reductive dechlorination happens when a chlorine atom is removed from an organic compound. Abiotic reductive dechlorination is often accomplished by the addition of zero-valent (elemental) iron (ZVI). ZVI Cloud Chamber Scrubber ® Best Technology Available for Submicron Particulate Tri-NOx® Multi-Chem® System • Wet destruct technology simultaneously removes SO2 and other acid gases.
