y All analyses was conducted by Acculab, Inc. a California-certified analytical laboratory,with two- <br /> week turnaround on results. <br /> 3.0 RESULTS OF INVESTIGATION <br /> �i <br /> 3.1 General Subsurface Conditions <br /> Backfill gravels and sands were encountered down to about 12 feet in depth(total depth)in boring <br /> IB-1 A and down to about 14.5 feet in depth in boring IB-1. Underlying native soils encountered in <br /> boring I13-1 consisted of grey green to brown sandy silt down to 20 feet in depth (total depth). <br /> Native soils encountered in boring IB-2 consisted of brown sandy silts and silty sands down to about <br /> 26 feet in depth. A dry, tan, medium-grained, loose sand was encountered in IB-2 from 26 feet to <br /> 28 feet in depth(total depth). No groundwater was encountered in the three borings. <br /> No hydrocarbon odors or staining were noted in soils recovered from any of the three investigative <br /> soil borings. <br /> 3.2 Results of Laboratory Analyses <br /> Soil and water analytical results are summarized in Table 1. The laboratory data report and chain-of- <br /> custody <br /> hain-ofcustody record for soil analyses is contained in Appendix C. <br /> Table l <br /> SUMMARY OF SOIL ANALYTICAL RESULTS <br /> Reid PIastics UST Site <br /> .laLWr�``;°�ngynr y € a�,le.r z`3.3a%_ <br /> 3°ee°€•'rsr aEs�t'_L 4 7cas <br /> Ing-g, a¢a - ; � 1nG ee 3r " Gez <br /> >iE'Itpl�5 N sa►flple¢"kl. �: K <br /> 'rig ,rs CndflC�ntration m tt �` i �x.,;rr€ " <br /> �., .7_.pt.h �' . ° e'cI d. <br /> .rte <br /> IB-1A.1 11.5 ft <1.0 <0.0050 <0.0050 <0.0050 <0.0050 <0.050 <br /> IB-1.1 15.0 ft <1,0 <0.0050 <0.0050 <0.0050 <0.0050 <0.050 <br /> i <br /> IB-1.2 20.0 ft <1.0 <0.0050 <0.0050 <0.0050 <0.0050 <0.050 <br /> IB-2.1 7.5 ft 2.0 <0.0050 <0.0050 <0.0050 <0,0050 <0.050 <br /> IB-2.2 12.0 ft <1.0 <0.0050 <0.0050 <0.0050 <0.0050 <0.050 <br /> IB-2.3 15.5 ft <1.0 <0.0050 <0.0050 <0.0050 <0.0050 <0.050 <br /> IB-2.4 lU ft <1.0 <0.0050 <0.0050 <0.0050 <0.0050 <0.050 <br /> IB-2.5 23.5 ft <1.0 <0.0050 <0.0050 <0.0050 <0.0050 <0.050 <br /> 1B-2.6 27.5 ft <1.0 <0.0050 <0.0050 <0.0050 <0.0050 <0.050 <br /> TPH-D=Total Petroleum Hydrocarbons as Diesel X=Xylene <br /> B=Benzene MTBE=Methyl-t-Butyl Ether <br /> T=Toluene <1.0=Not detected above the expressed value. <br /> E=Ethyl benzene <br /> I <br /> it <br /> i <br /> l <br /> ' PORT OF Bp INVESTIGATIONGRIBI Associates Page 4 REID PLASTICS UST SITE f GA <br /> 172A1-01 <br />
