This <br /> area will be resampled,and the soil samples will be analyzed for CAM 17 metals plus <br /> O <br /> SRI SBI-5 soil 5.0 X X X tin and selectively anaylzed for VOCs and SVOCs as requested by DTSC. <br /> 1 <br /> Multibond Line Room SB2 8132-1 soil first native X In 2001,the secondary containment structures were still in place and only concrete <br /> samples were collected.One soil boring will be advanced along the apparent footprint <br /> SB2 S132-5 soil 5.0 X X of the secondary containment area,and soil and groundwater samples will be <br /> collected and analyzed for copper and VOCs,based on knowledge of previous <br /> S132 SB2-GW groundwater groundwater x x X chemical use.The groundwater sample will be also analyzed for CAM 17 metals plus <br /> �l NA Trip Blank'* DI Water X tin and SVOCs as requested by DTSC. <br /> SB24-GW <br /> Lead,tin and ammonia are included due to chemical use during Citation Enterprises <br /> DES Line SB3 SB3-1 soil first native X X X X X plating activities within the room.In December 2001,one soil and one concrete <br /> sample were collected and analyzed for copper.Copper was detected at 8.7 mg/kg. <br /> One soil and one groundwater sample will be collected to verify that no past releases <br /> have occurred,and they will be analyzed for copper,lead,tin,ammonia,and ethylene <br /> glycol butyl ether.
