e . e !\P/'fN01Y. r-~ AET No, 03-00944- Page 6 . PAH analysis of soil from GP-l (2-4'), GP-l (12') and GP-3 (2-4') revealed low concentrations of several PAR compounds. PAH concentrations were not detected in the soil samples from GP-2 (2-4'), GP-2 (12'),and GP-3 (7-8'), . Groundwater Analytical Results Groundwater samples were collected from GP-l, GP-2 and GP-3, A summary of groundwater analysis fIndings is listed below and shown on Table 2, Appendix C contains the Legend report, . DRO analysis of groundwater from GP-2 showed a concentration of 320 parts per billion (Ppb) , No concentrations of DRO above the laboratory deteetion level were noted in groundwater collected form GP-l and GP-3, The DRO noted within the groundwater of GP-2 was noted by the laboratory as being atypical of petroleum products, The chromatogram for this sample is attached to Legend's report. . No PAR concentrations were detected in the groundwater samples submitted for analysis. DISCUSSION AND CONCLUSIONS The results of this Limited Soil/Groundwater Assessment reveal the following conclusions: . Low eoncentrations of DRO and PAR contaminated soil exists within the fill soils of GP-l and GP-3, and DRO was noted within the surficial groundwater of GP-2. . Since DRO coneentrations were noted by the laboratory as atypieal of petroleum products, it is likely the DRO concentrations are due to the existenee of PAR contaminants. . The PAR concentrations noted within fill soils from GP-l and GP-3 are eonsidered low and are below MPCA established Tier 2 (Industrial) Soil Reference Values (SRVs).
