<br /> Metalsa Structural Products,Inc.—1550 Industrial Drive,Stockton,California
<br /> Sample Sample I.D. Sample Depth(s) Analysis Rationale
<br /> Location (ft)
<br /> Soil
<br /> B-3 B-ldx' 6,8, 10 VOCs,TPH,PAHs,and Title 22 metals Adjacent to below-grade sump
<br /> B-4 B-4dx' 6,8, 10 VOCs,TPH,PAHs,and Title 22 metals Adjacent to below-grade sump
<br /> B-5 B-5dx' 6,8, 10 VOCs,TPH,PAHs,and Title 22 metals Adjacent to below-grade sump
<br /> B-7 B-7dx' 6,8, 10 VOCs,TPH,PAHs,and Title 22 metals
<br /> Dup-1 Dup-ldx' 6,8, 10 VOCs,TPH,PAHs,and Title 22 metals
<br /> Background Soil
<br /> BG-1 BG-ld6' 6 Title 22 Metals Sample location away from site operations,same depth as primary sample
<br /> BG-2 BG-2d6' 6 Title 22 Metals Sample location away from site operations,same depth as primary sample
<br /> BG-6 BG-6d6' 6 Title 22 Metals Sample location away from site operations,same depth as primary sample
<br /> BG-8 BG-8d6' 6 Title 22 Metals Sample location away from site operations,same depth as primary sample
<br /> Groundwater
<br /> B-34 B-3-4 35-50* VOCs,TPH,PAHs,and Title 22 metals Presumed down gradient of below-grade sumps
<br /> B-5 B-5 35-50* VOCs,TPH,PAHs,and Title 22 metals Presumed down gradient of below-grade sump
<br /> B-7 B-7 35-50* VOCs,TPH,PAHs,and Title 22 metals Presumed down gradient of below-grade sump/chemical storage area
<br /> TB-1 TB-1 VOCs QA/QC sample,prepared by lab,with samples during hold time/shipment
<br /> Dup-1 Dup-I VOCs QA/QC sample,blind duplicate of sample B3-4
<br /> EB-1 EB-1 VOCs QA/QC sample,equipment decontamination verification
<br /> AB-1 AB-1 VOCs QA/QC sample,affect of ambient conditions during sampling
<br /> Notes: Depth of soil sampling is 6'(5.5-6.0'),8'(7.5-8.0'),and 10'(9.5-10.0').Additional soil samples will be collected and analyzed if field screening(staining,odor,or PID readings)
<br /> indicate impact may be present.Soil samples collected at depth of 6 feet will be analyzed and others held.
<br /> TPH total petroleum hydrocarbons as diesel and oil range hydrocarbons)
<br /> PAHs polycyclic aromatic hydrocarbons
<br /> Title 22 Metals Ag,As,Ba,Be,Cd,Co,Cr,Cu,Hg,Mo,Ni,Pb,Sb,Se,TI,V,Zn
<br /> VOCs volatile organic compounds
<br /> ft feet
<br /> * Estimated depth,actual depth based on field observations during drilling.
<br /> Background soil samples collected at depth of 6 feet will be analyzed.Additional BG samples will be collected at 8 and 10 feet and held.
