In Situ Chemical Reduction for Remediation of Soil Containing Chlorinated Pesticides and Herbicides(PPT)

摘要

Adventus manufactures a family of in situ chemical reduction (ISCR) products (i.e., soil amendments) for treatment of soil, sediment and other solid wastes contaminated with halogenated organic compounds. When the contaminants of interest are organochlorine pesticides (OCPs) or herbicides, the keys to this remedial approach are the composition of the soil amendment and application of repeated and sequential anoxic then oxic conditions to the contaminated matrix. The patented products are composed of plant fiber-based organic material and micro-scale elemental iron (U.S. Patent No. 6,083,394) and may be supplemented with sulfate in the form of alkaline earth salts.
