One soil sample from each boring obtained near the water table for <br /> total petroleum hydrocarbons as gasoline. i <br /> 2. One ground-water sample from each monitoring well for benzene, F <br /> -~ toluene, and xylene (BTX). <br /> E i <br /> The results of these chemical analyses are presented on Plate 5. I <br /> SURFACE.AND SLBSLRFACE CONDITIONS <br /> ..... <br /> ii Well MW-5 and Borings/Probes P-1 and P-2 are located at the northeast <br /> corner of the 7-Eleven in a planter area. This area consists of several <br /> shrubs and bark chips overlying black plastic._ MW-5 encountered stiff <br /> WE <br /> clayey sols down to 10 feet where a gravelly sand was encountered.
