i CONCLUSIONS 1 It is not yet possible to determine if natural attenuation is taking place, although MW-1, which has recorded the highest levels of all components since monitoring began, has shown a significant reduction in those levels during the last two sampling events 2 MW-2 has not shown any contamination since the December, 1995 sampling, which appears to define the limits of the plume in that direction 3 The hydraulic gradient has remained rather constant to the north/northwest at around 006 ' /ft , suggesting that there are no withdrawal points within the zone of influence of the property 3 The extent of soil and groundwater contamination have not been fully defined to the north RECOMMENDATIONS Our client has not yet received a letter of committment from the Cleanup Fund, and they have been unable to determine the status of their claim They have been diligent in complying with all rules and requirements to date the UST has been removed, con- taminated soil properly disposed of, and three soil borings and three monitoring wells placed on the property Any further work that may be required will be difficult due to presence of water & sewer lines, and the office budding and warehouse Until the company has been reimbursed for costs incurred to date, or at least receive a letter of committment from the Fund, we do not believe that additional work is justified at this time We recommend that quarterly monitoring continue for a minimum of two more periods At that time we will conduct a thorough review of the project, and make appropriate recommendations If you have,,any questions concerning this report, please contact our o �c t (916) 972-7941 Wm J u ter & Associates tp Geo c ul Souva, Valley Wholesale Drug Co Beth Thayer, RWQCB MLLLWJ HUNTER NO 860 cAUF 2
