Harding Lawson Assaclatas <br /> ' V. CHEMICAL ANALYSES <br /> _; <br /> Our investigations have included a variety of chemical anal- <br /> f Yses on soil and water samples to better characterize the types <br /> gasoline <br /> and concentrations ofYp <br /> hydrocarbon constituents at the <br /> ? site. Not all analyses were <br /> performed an every sample. The <br /> � �~ <br /> testing g � <br /> ti g pro ram was adjusted to the emphasis in each phase. <br /> $ Tables 2 through 5 summarize the results of all analyses on soli j <br /> 4 and ,water samples.
