Ethylbenzene and xylene (less than 0 015 mg/kg) in Borehole (BH) No C-3 and less than 0 065 mg/kg in BH No C-5/7) and contamination with header fractions (purgeable C6-C12) were found in soil between 25 and 40 FT bgs Additionally, in BH Nos C-2, C-4/6, and C-5/7 extractable petroleum hydrocarbons ranging upwards to 15,500 mg/kg at 25 FT bgs were found Groundwater was sampled when encountered in the boreholes MW No 1 was sampled on December 20, 2000 and March 30, 2001 A detectable level of BTEX of 0 500 ug/L was found in BH No C-4/6 Extractable hydrocarbons were identified in groundwater samples from BH Nos_C-1, C-2, C-3, CA C-5 and MW_No 1 Ground water was sampled from the single monitoring well in December 2000, April 2001, January 2002, and April 2002 Recent Activity Following resumption of monitoring in 2002, it became apparent that additional characterization of contamination both on and off site would be required After conditional approval by your office (EHD), six borings of which five were converted to cased monitoring wells were constructed by Woodward Drilling Company during June 6 and 7, 2002 Soil was sampled and classified by Stellar Environmental Solutions, Inc geologist Fred Hayden RG and Dan Barber PE Del-Tech Geotechnical Support Services developed the monitoring wells and continues to collect samples from MW Nos 1-6 for delivery to Sequoia Laboratory for analysis tWell Top of Casing (TOC) elevations were established to 0 01 FT accuracy and related to the datum of the surrounding Victor Fine Foods ground water monitoring program by Daniel K Barber P E General Findings to Date Soil source areas with remaining diesel contamination have been identified One of the contamination zones may extend into the adjacent eastern parcel from the ' original UST excavation area Significant but economically feasible to remove contamination exists between MW Nos 1 and 2 near the site's eastern property line fence Alternative methods of soil remediation are being weighed and will be proposed in late May 2004 in a separate document The site's groundwater flow, based on June 26, 2004 Monitoring Well information is northeastward, at a gradient averaging 0 002 FT/FT declining at an average bearing of N 50-60 deg E Please reference ATTACHMENT 5, GROUNDWATER GRADIENT AND BEARING CALCUATIONS Diesel range hydrocarbons vaned 1 between <0 05 and 0 66 mg/Itr in the monitoring wells Previously MW No 3 was i 2
