Laboratory Analyses <br /> All samples will be analyzed under standard one-week turnaround-times following submittal to the <br /> laboratory. Laboratory analyses are listed on the Sample Analysis Matrix and Summary(Table 1) and <br /> will include the following: <br /> ADL Sampling along 11th Street and MacArthur Drive <br /> • 36 soil samples for total lead using Environmental Protection Agency(EPA)Test Method 6010 <br /> • Soil samples with total lead concentrations that exceed ten times the STLC will be further <br /> analyzed for WET lead <br /> • Soil samples with WET lead concentrations that exceed the STLC may be further analyzed for <br /> DI-WET and/or TCLP lead <br /> • 4 soil samples for pH using EPA Test Method 9045 <br /> Soil and Grab-Groundwater Sampling adjacent to UPRR ROW <br /> • 12 soil and 4 grab-groundwater samples for CAM 17 metals using EPA Test Method 6010/7000 <br /> • 8 soil samples for polynuclear aromatic hydrocarbons(PAHs)using EPA Test Method 8270 <br /> • 8 soil and 4 grab-groundwater samples for total petroleum hydrocarbons as gasoline(TPHg), <br /> benzene,toluene, ethylbenzene,and xylenes(BTEX), and methyl-tert-butyl ether(MTBE)using <br /> EPA Test Method 8021M <br /> • 8 soil and 4 grab-groundwater samples for total petroleum hydrocarbons as diesel and as motor oil <br /> (TPHd/mo)using EPA Test Method 8015M <br /> Soil Sampling for Private Properties Proposed for Partial Acquisition <br /> • 16 soil samples for CAM 17 metals using EPA Test Method 6010/7000 <br /> • 8 soil samples for TPHd/mo using EPA Test Method 8015M <br /> • 8 soil samples for pesticides using EPA Test Method 8081 <br /> Soil Sampling at Proposed Borrow Area <br /> • Instruct the analytical laboratory to composite 16 samples into four 4-part composites samples <br /> (Comp-0',Comp-1',Comp-2',and Comp-4') <br /> • 4 composite soil samples for CAM 17 metals using EPA Test Method 6010/7000 <br /> • 4 composite soil samples for TPHd/mo using EPA Test Method 8015M <br /> • 4 composite soil samples for TPHg,BTEX, and MTBE using EPA Test Method 8021 M <br /> • 4 composite soil samples for pesticides using EPA Test Method 8081 <br /> • 4 composite soil samples for herbicides using EPA Test Method 8151. <br /> Project No.E8504-06-01 -7- July 13,201 I <br />
