1 <br /> consistent with the types of soils present in the subsurface (F e , the organic <br /> content of clays is generally higher than sands) <br /> 2.3 SLUG TESTING RESULTS <br /> iTo aid in the evaluation of site h dro eologY, ERM performed slug testing <br /> in monitoring wells MW-1, MW-2, MW-4, and MW-6 Slug testing <br />' procedures and analysis methods are presented in Appendix C along with <br /> the test results <br /> iThe analysis of the slug test results indicates that the aquifer hydraulic <br /> conductivity ranges from 181 x 10-5 centimeters per second {cm/sec} at <br /> 1 MW-4 to 159 x 10-3 cm/sec at MW-1 These data correlate to the <br /> hydrogeologic data presented previously <br />' The results of the slug tests indicate that the hydraulic conductivity of the <br /> shallow soils is relatively low This is further shown by the limited <br />' migration of TPH-g and BTEX in ground water at each UST location <br /> Based on sampling at the site, the downgradient extent of TPH-g and <br /> BTEX compounds at each former tank location is less than 150 feet,which <br /> would be expected since the tanks were taken out of service in the 1960s <br /> The limited migration of chemicals at the site is also suggestive of low <br /> hydraulic conductivity soils <br /> i <br /> 1 <br /> 1 <br /> I <br /> 1 <br /> 1 <br /> • <br /> 1 <br /> 1 6 <br />
