Ripona Market <br /> Soca & Groundwater Investigation ReO <br /> Nge 2 <br /> ILaboratory soil samples were obtained every five feet, below the gravel layer, for <br /> laboratory analysis since contaminated soils were placed back in the tank pit The ten <br />' and twenty foot samples were non detect for all compounds analyzed The 15 foot <br /> sample contained only 19 µg/Kg of xylenes MTBE was present at 25 and 30 feet in <br /> depth The sample with the highest concentration of MTBE, B-1-25', was analyzed by <br />' method 8260 for all of the oxygenated compounds and found to contain 960 µg/Kg of <br /> MTBE <br /> The groundwater sample was obtained by driving a hydropunch type well screen from 30 <br /> to 34 feet in depth The water sample contained low levels of Toluene, Xylenes, and <br /> MTBE at 10 µg/L <br />' Table of Laboratory Sample Results (1131/00) <br /> I Sample I D Gasoline Benzene Toluene E-Benzene Xvlenes MTBE 8264 <br /> B-1-10 ND ND ND ND ND ND NA <br /> B-1-15 ND ND ND ND i 9 ND NA <br /> B-1-20 ND ND ND ND =ND ND NA <br /> B-1-25 ND ND ND ND ND 1300 960µ <br /> B-1-30 ND ND ND ND ND 170 NA <br /> B-1-H,0 ND ND 0 /L ND 13 NA 10 <br /> \D=\ON-DETECT NA=Not Anatwed <br />�. 21 Drilling <br /> The soil boring was accomplished using a mobile mounted Geoprobe' Systems <br /> drilling rig, Model 5400, employing the use of a 1 25" hollow probe rods All <br /> drilling equipment was thoroughly steam cleaned before drilling began to prevent <br /> the introduction of contamination from off site, and between borings to prevent <br /> cross contamination <br /> The boring was logged under the direct supervision of a registered geologist using <br /> the Unified Soil Classification System The color, texture, moisture, plasticity (if <br /> applicable), consistency of the earth materials, pertinent soil or bedrock <br /> characteristics, and any evidence of contamination will be noted All water-bearing <br /> zones and the depths at which they are encountered are noted on these logs <br /> The boring was drilled in such a manner as to prevent cross contamination between <br /> strata Water samples were taken at the soil/groundwater interface, and the borings <br /> were then terminated with a cement mixture <br /> 2.2 Soil Sampling <br /> All soil sampling equipment was thoroughly steam cleaned before and between <br /> sampling to prevent cross contamination Relatively undisturbed soil samples were <br /> taken at intervals of not more than five feet (5') in order to evaluate the subsurface <br /> materials <br /> I <br />
