Based on the results of groundwater sample analyses, <br /> monitoring wells MW-203B(1), MW-203B(2), and MW-203B(3) were installed and screened <br /> across three depth intervals in the B-zone aquifer. This work was conducted from May 19 <br /> through 29, 1997 (Figure 1). <br /> • Survey activities were conducted on April 14 through 18, 1997, to obtain top-of-casing <br /> elevations for newly repaired monitoring wells MW-1 through MW-4 and MW-8, and newly <br /> installed monitoring well MW-102; and to obtain horizontal locations and ground surface <br /> elevations for the soil-vapor sample locations and the CPT/PIPP borings installed during the <br /> source area investigation and the Interim Remedial Action (IRA) activities. <br /> • Access negotiations continued with private property owners and their tenants to obtain <br /> permission to conduct Remedial Investigation and IRA activities on adjacent properties. <br /> Although access agreements have been finalized between the SDCDs and the neighboring <br /> property owners and tenants at Lincoln Center, permission to proceed with the field work has <br /> not yet been received from all of those parties. <br /> 411 t-E97.BMM:SRL 2 <br />
