' Chromium, lead, nickel and zinc were detected at background concentrations in each sample from <br /> GP9 to GP12 No other constituents were detected in the samples analyzed from GP9 to GP12 <br /> Organic vapors and hydrocarbon odors were not detected in any samples fi om probings GP9 to <br /> GP12 I <br /> ' Xylenes were detected in the ground water sample from GP12 at a concentration of 0 70 ppb <br /> Chromium, nickel and zinc were detected at concentrations of 0 14 ppb, 0 16 ppb and 0 50 ppb <br /> ' respectively No other constituents were detected in the water sample collected from penetration <br /> GP12 <br /> 1 <br /> 1 <br />
