' All drilling equipment will be cleaned prior to arrival at the site. To avoid cross-contamination, <br /> all appropriate downhole drilling and sampling equipment will be cleaned between borings. <br /> ' Drill cuttings and groundwater generated from the investigation will be contained in United <br /> Nations approved 55-gallon drums and temporarily stored on site, pending laboratory analysis to <br /> ' determine disposal alternatives. <br /> ' 2.1.4 Well MW-5 Repair <br /> Monitoring well MW-5 will be repaired and raised approximately 18-inches. A slip union will <br /> ' be used to extend the rim of the well casing above any standing water. The surface seal will be <br /> rebuilt to include a stovepipe protective covering. <br /> ' 2.2 Remedial Options Feasibility Study <br /> ' The remedial options feasibility study (FS)will follow the general guidelines required by <br /> CERCLA. The first phase of the FS includes the development of remediation alternatives by: <br /> ' 1. Developing remedial action objectives by specifying the contaminants and media <br /> of interest, exposure pathways, and preliminary remediation goals. <br /> 1 <br /> 2. Developing general response actions for each media of interest that may be taken <br /> ' to satisfy the remedial action objectives for the site. <br /> ' 3. Identifying volumes or areas of media to which general response actions might be <br /> applied. <br /> ' 4. Identifying and screening the technologies applicable to each general response <br /> ' action to eliminate those that cannot be implemented technically at the site. <br /> ' 5. Identifying and evaluating technology process options to select a representative <br /> process for each technology type retained for consideration. <br /> ' 6. Assembling the selected representative technologies into alternatives representing <br /> a range of treatment and containment options. <br /> ' 9 <br /> 1 <br />
