5.0 REMEDIATION <br /> 5.1 Remedial Objectives <br /> Remedial objectives are identified to provide direction in developing remedial actions neces- <br /> sary to achieve the aforementioned goals. Remedial objectives also serve as a baseline for <br /> measuring achievement. Since significant hydrocarbon impacted soil has not been identified <br /> beneath the site to date only groundwater-based objectives have been identified. These <br /> objectives are identified below. <br /> • Groundwater. Within technical and economic constraints: (1) achieve <br /> secondary water quality goals; (2) prevent the use of, or exposure to, petro- <br /> leum hydrocarbon affected groundwater until water quality goals are met. <br /> Given the course of change, and the nature of remediation, these remedial objectives may <br /> change. For example, site water quality goals may need to be modified due to technical and <br /> economic constraints. To terminate all remediation efforts (including groundwater monitoring <br /> and engineered health and safety management controls), it must be shown that leaving residual <br /> concentrations in place will be consistent with the maximum benefit to the people of the State, <br /> and not unreasonably affect present and probable beneficial uses of groundwater. <br /> 5.2 Technology Identification and Screening <br /> The general response actions necessary to achieve the remedial objectives are: <br /> 1. Dissolved-petroleum hydrocarbon plume management. <br /> 2. Reduce the mass of petroleum hydrocarbons identified in groundwater. <br /> 3. Complete dissolved hydrocarbon delineation. <br /> The general response actions are used to focus the transition from remedial objectives to tech- <br /> nological applications. Each response action addresses one or more of the remedial objec- <br /> tives. <br /> 3201357B/CAPREVI l 1 June 29, 1995 <br />
