FINDINGS <br /> Soil descriptions, shallow site stratigraphy, and ground water elevations were determined from field <br /> data Hydrocarbon-impacted soil and ground water were characterized from field and laboratory <br /> analytical data <br /> 41 SOIL PROFILE <br /> Generally, a brown, damp, sandy silt/silty sand was encountered from surface grade to depths of <br /> approximately 15 feet bsg in each boring A brown, damp, silty clay was generally encountered from <br /> Advanced G[roi=n\iron mental,Inc <br />
