Your monitoring program may be specified for your site by the regulatory agency with site jurisdiction. At a minimum, your monitoring program should incorporate the contaminants of concern and reduction-oxidation (REDOX) potential. Field parameters including pH, conductivity and dissolved oxygen are also recommended. Apparent turbidity, observed as a faint white tint, can sometimes be used as a visual indicator of EOS® presence.
A more detailed monitoring program could include inorganic compounds (e.g., nitrate and sulfate), metals (e.g., iron and manganese), total organic carbon, light hydrocarbon gases (methane, ethane, ethene) and possibly volatile fatty acids. Increasingly complex sites could also monitor for phospholipids fatty acids and a variety of Molecular Biology Tools that would include population counts for Dehalococcoides ssp., other dehalogenating microorganisms, and functional genes.
