April 22, 1987 AGS 8691-6 <br /> Beacon Service Station #1-502 - Lodi, California <br /> CONCLUSIONS <br /> The results of laboratory analyses indicate that the levels of <br /> contamination are significantly lower in MW-5 than in MW-1, MW-2, <br /> or MW-4, which were installed nearer to the tank cavity at the <br /> site. The hydrocarbon concentrations detected in MW-5 are below <br /> action levels established by the California Department of Health <br /> Services except for benzene. Ground water flow is oriented to <br /> the south southwest, or toward MW-5 from the area below the tank <br /> cavity. We interpret the results of chemical analyses to <br /> indicate that dissolved contaminant migration has been limited, <br /> and probably does not extend far beyond the limits of the site to <br /> the south. <br /> RECOMMENDATIONS <br /> Hydrocarbon contamination is present at the site in the soil <br /> below the tank cavity and above the ground water surface and as <br /> dissolved constituents of ground water at the site. The levels <br /> of contaminants detected decrease significantly with distance <br /> from the area below the tank cavity. <br /> 11 <br /> .4,00�;ed GeoSystems <br />
