<br />Former Lexington School <br />STS Project #95192- XF <br /> <br />The tank was hoisted from the excavation by securing a chain around the tank. With the <br />tank above ground. observations as to the condition of the tank were made. <br /> <br />Upon completion of visual observations of the tank, the tank was loaded onto a flat bed <br />trailer and shipped to Petro Tank Service's yard, where the tank was to be cleaned and cut <br />up for scrap metal. <br /> <br />Tank and Piping Conditions <br /> <br />Once the tank was removed from the excavation. conditions of the tank were noted. The tank <br />had a light scratch and a small dent due to the tank being bumped during excavation; how- <br />ever. it appeared to be in generally sound condition. No holes in the tank or cracked or <br />broken welded seams were observed. <br /> <br />Piping was in a generally sound condition. No cracks or broken connections were observed <br />on the supply and return piping. <br /> <br />Soil Sample Screening and Testing <br /> <br />Soil screening for petroleum impacts included visual and olfactory observations and photo- <br />ionization meter screening methods. Visual observations included observations for dis- <br />colored soils and observations for the presence of free product in the soil. Soil samples <br />were also screened with an HNU photoionization meter for the presence of petroleum con- <br />tamination. <br /> <br />The HNU meter is a portable instrument used to detect and measure the concentration of a <br />variety of volatile organic compounds (VQC's) in air. The HNU meter uses a 10.2 eV <br />lamp calibrated to a benzene reference. Soil samples were placed in clean glass sample <br />containers and capped. The samples were than agitated and an HNU deflection measuring <br />VOC's as HNU units was obtained from the head space over the sample in the jar. Soil <br /> <br />- 3 - <br />
