TABLE 3 <br /> PARAMETERS FOR PILOT TEST PERFORMANCE MONITORING <br /> Crop Production Services, Inc. <br /> 1905 N.Broadway Avenue <br /> Stockton,California <br /> Parameter Method Rationale/Notes <br /> Dissolved Gasses <br /> Carbon dioxide,ethane,ethene, Elevated levels of methane indicate fermentation is occurring in a anaerobic environment and that reducing conditions are appropriate for <br /> methane,and propene RSK 175 dechlorination to occur. Methane concentrations greater than 0.5 mg/L are generally indicative of anaerobic degradation and concentrations <br /> greater than 1.0 mg/L are desirable,but not required(AFCEE,2004).Propene is a by-product of the abiotic dechlorination process. <br /> Biological <br /> Denitrifying and Dechlorinating Various Denitrifying and dechlorinating bacteria should be present in sufficient amounts for favorable nitrate and chlorinated compound degradation <br /> Bacteria conditions. <br /> Notes: <br /> Nitrate reported as Total Oxidized Nitrogen[TON],nitrate-N+nitrite-N) <br /> Total Ammonia-N=Ammonium-N+ammonia-N <br /> Utilization of electron acceptors(nitrate,manganese,iron,sulfate,etc.)in an anaerobic system can also occur simultaneously. <br /> mg/L=milligrams per liter <br /> References: <br /> Air Force Center for Environmental Excellence(AFCEE).August 2004.Principles and Practices of Enhanced Anaerobic Bioremediation of Chlorinated Solvents. <br />
