• 5.0 REMEDIATION 5.1 Remedial Objectives Remedial objectives are identified to provide direction in developing remedial actions neces- sary to achieve the aforementioned goals Remedial objectives also serve as a baseline for measuring achievement Since soil-based water quality goals have been achieved, only groundwater-based objectives are identified below • Groundwater Within technical and economic constraints (1) achieve secondary water quality goals, (2) prevent the use of, or exposure to, petro- leum hydrocarbon affected groundwater until water quality goals are met Given the course of change, and the nature of remediation, these remedial objectives may change For example, site water quality goals may need to be modified due to technical and economic constraints To terminate all remediation efforts (including groundwater monitoring and institutional controls), it must be shown that leaving residual concentrations in place will be consistent with the maximum benefit to the people of the State, and not unreasonably affect present and probable beneficial uses of groundwater 5.2 Technology Identification and Screening The general response actions necessary to achieve the remedial objectives are 1 Dissolved-petroleum hydrocarbon plume management 2 Reduce the mass of petroleum hydrocarbons identified in groundwater 3 Complete dissolved hydrocarbon delineation The general response actions are used to focus the transition from remedial objectives to tech- nological applications Each response action addresses one or more of the remedial objec- tives 5.2.1 Technology Screening Resolution 92-49 was consulted for applicable technologies, as was available literature Only technologies that would apply to site-specific conditions were considered, and technologies 3201357BICAP 10 April 4, 1995
