4 Summary of RI Findings Hydrocarbon impacted soil 5-14 bgs Highest PCBs in soil Shallow (1.5-2 bgs): 4020 mg/kg. Deep ( bgs): 9800 mg/kg Highest VOC (TCE) in GW 550 ug/l (28 30 bgs). Most values at or below 10 ug/l. PCBs absent in groundwater. Profile View 4

5 Summary of RI Findings (Cont d) Relative Incidence of PCB Aroclors in RI Samples Collected Aroclor % % % % ND 1% << Highest Incidence 5

6 Remedial Alternative Evaluation No Action Excavation and Off-site Disposal In-situ Dual Phase Extraction In-Situ Chemical Oxidation Fenton s Ozone Persulfate Permanganate Literature Review Pilot Test ROI Bench Study #1 Bench Study #2 6

7 ISCO with Ozone Robust body of real world case histories for effectiveness of Ozone on site COCs (except PCBs) Ozone effective on PCBs in microcosm Conducted site specific Bench and Pilot Scale Testing Site conditions ideal 7

8 Bench & Pilot Results Persulfate showed varied reductions (approximately 50% - 85%); approach is dependent on conditions / mixing / contact efficiency Ozone showed most effective reduction (>90%); approach is dependent on delivery efficiency Fenton s was not efficient ROI range from 10.5 to 30+ feet 8

9 Geomorphology of plume in the matrix ROI, permeability, DTW Benefits ISCO with Ozone (O 3 ) No disposal No dioxin production No toxic bi-products Variability in delineation easily addressed 9
