Semiannual thereafter. <br /> Baseline(prior to injection),six, <br /> Suite B and twelve months after injection. Treatment Zone' <br /> Annual thereafter. <br /> Baseline(prior to injection),three, <br /> Suite A six,and twelve months after Treatment Zone' <br /> MW-10 5 injection. Semiannual thereafter. <br /> Baseline(prior to injection),six, <br /> Suite B and twelve months after injection. Treatment Zone <br /> Annual thereafter. <br /> Baseline(prior to injection),six, <br /> Suite A and twelve months after injection. Compliance' <br /> MW-6 Semiannual thereafter. <br /> Baseline(prior to injection),and <br /> Suite B twelve months after injection. Compliance' <br /> Annual thereafter. <br /> Baseline(prior to injection),six, <br /> Suite A and twelve months after injection. Compliance' <br /> MW-7 Semiannual thereafter. <br /> Baseline(prior to injection),and <br /> Suite B twelve months after injection. Compliance' <br /> Annual thereafter. <br /> Baseline(prior to injection),three, <br /> MW-3A Suite B six,and twelve months after Background <br /> injection. <br /> Baseline(prior to injection),three, <br /> MW-9 Suite B six,and twelve months after Background <br /> injection. <br /> 1 Well numbers and locations as shown on Figure 1-2. <br /> 2 Suite A includes TPH-g,TPHd,BTEX,MTBE,Naphthalene,nitrate,sulfate.Suite B includes metals(dissolved), <br /> total chromium,hexavalent chromium,total dissolved solids,bromide,and bromate. <br /> 3 Wells sampled to evaluate in-situ bioremediation progress inside the treatment zone. <br /> 4 Wells used to determine compliance with water groundwater limitations. <br /> 5 Well MW-10 is characterized as Treatment Zone well because it lies within the injection area. However,well MW-10 is <br /> screened in deeper zone(93.5 to 103.5 feet bgs)compared to MW-2,which is screened in shallow zone(30 to 45 feet bgs). <br /> 6 Wells used to develop background concentrations. <br />
