<br /> Notes:
<br /> Sample collected by Geological Technics,Inc.,of Modesto,California,and analyzed by Sherwood Labs Corp.
<br /> 8015M,and by Sequoia Analytical of Sacramento,California,for VOCs using EPA Method 8240. °f Hilmar,California,for TPHg,TPHd,TPHmo,and TPHk using EPA Method
<br /> z Samples collected by Radian International and analyzed by Core Laboratories of Anaheim,California,for TPHg,TPHd,and TPHmo using EPA Method 8015M,BTEX and MTBE using EPA
<br /> Method 8020,and PAHs using EPA Method 8270.
<br /> 3 Samples collected by Geomatrix Consultants,Inc.,of Oakland,California,and analyzed by Friedman&Bruya of Seattle,Washington for TPHg and TPHd using EPA Method 8015M, BTEX using
