LFR Inc. <br /> degradation products must be measured to determine treatment effectiveness. The <br /> monitoring schedule takes into account the possibility that it may take several months <br /> for the system to evolve to reducing conditions. <br /> Existing and proposed groundwater monitoring wells were incorporated into the system <br /> start-up and periodic monitoring program. Monitoring locations are presented in the <br /> following table. The monitoring well network consists of(a) 22 ERD injection wells, <br /> (b) two upgradient monitoring wells, (c) six ERD area monitoring wells, and (d) seven <br /> downgradient area monitoring wells. <br /> Monitoring frequency is presented in the following table. Descriptions of each type of <br /> measurement are presented below. <br /> Summary of Monitoring Program <br /> Data ERD Upgradient ERD Area Monitoring Downgradient Monitoring <br /> Collection Injection Monitoring Wells Wells <br /> Wells Wells <br /> 22 proposed MW-004A Existing wells MW-108A, Existing wells MW-113A, <br /> injection wells MW-020B MW-205B, and MW0301C MW-114A, MW-207B, and <br /> New wells MW-121A, MW-208B <br /> MW-122A, and MW-214B New wells MW-124A, <br /> MW-123A, and MW-215B <br /> Injection Volumes hourly semiannually <br /> and Rates <br /> Contaminants and after semiannually baseline, during injection, baseline, quarterly <br /> Daughter Products development months 1 and 2, quarterly <br /> Field after semiannually baseline, during injection, baseline, quarterly <br /> Biogeochemical development, months 1 and 2, quarterly <br /> Parameters quarterly <br /> Laboratory semiannually baseline, during injection, baseline, quarterly <br /> Biogeochemical months 1 and 2, quarterly <br /> Parameters <br /> Organic Substrate baseline, semiannually baseline, during injection, baseline, quarterly <br /> Indicators quarterly months 1 and 2, quarterly <br /> 4.3.1 Sample Collection Methods <br /> Groundwater samples will be collected immediately before the injection event. To <br /> optimize representative groundwater sampling, sample collection methods will be <br /> employed that are specific to the ERD Phase V IRA. These sample collection methods <br /> are described below. <br /> wp-PhV_IRASep07-Firal-06750.doc:Itr Page 25 <br />
