Dry Wells Remedial Investigation <br /> Lawrence Livermore National <br /> Laboratory Site 300 <br /> San Joaquin County -3- 21 September 1990 <br /> (attached) , which states that "[a]II surface and ground waters of the State are <br /> considered to be suitable, or potentially suitable, for municipal or domestic water <br /> supply and should be so designated by the Regional Boards" , except in the situations <br /> specified in paragraphs 1(a) and 3 of the Resolution. Therefore, the protected water <br /> body to be considered in the DLM analyses is the ground water nearest the dry wells, <br /> unless LLNL demonstrates otherwise in accordance with the Resolution' s provisions. <br /> Conclusions and Recommendations <br /> Although LLNL has obtained numerous data concerning the hydrogeology in the vicinity <br /> of the specific dry wells, they have not demonstrated that the wastes shall not migrate <br /> to the nearest ground water and impair the aquifer's beneficial uses. As discussed <br /> above, LLNL needs to address the potential for each dry well to degrade the shallow <br /> aquifer. They should: <br /> 1 . Employ, for each dry well , an environmental fate analysis such as the DLM to <br /> establish acceptable soil concentrations for each waste constituent, and <br /> 2. Clearly justify recommendations resulting from the analyses, including <br /> calculations, maps, and drawings. <br /> MLH:gs <br />
