• Page 2 March 19, 2003 Ethylbenzene and xylene (less than 0 015 mg/kg reported in Borehole (BH) No iC-3 as well as ethylbenzene and xylene (less than 0 065 mg/kg reported in BH No C-5/7) and contamination with heavier fractions (purgeable C6-C12) were found in soil between 25 and 40 FT bgs in BH Nos C-2 and C-4/6, ranging upwards to extractable petroleum hydrocarbons of 15,500 mg/kg at 25 FT bgs in ' BH No, C-5/7 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, C-4, 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 this year, it became apparent that additional characterization of contamination both on and off site would be required Fallowing conditional approval by EHD, six borings of which five were converted ' to cased monitoring wells were constructed by Woodward Drilling Company during dune 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 Well 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 ' Three soil source areas with diesel contamination have been identified One of the contamination zones may extend into the adjacent eastern parcel between ' already installed MW Nos 5 and 6 although soil contamination was not found and levels less than 0 3 mg/kg of diesel were found in the groundwater sample ' Groundwater contamination at between 50 to 55 FT bgs exists and likely extends north of the site's property While the leading edge waits to be defined, the original source underground storage tanks (USTs) is removed, levels are low and ' the closest down gradient offsite well is at least 600 FT away Additionally, residual soil contamination possibly contributing to the contamination has been identified and removal is anticipated The site'sroundwater flow, based on current Monitoring Well information is 9 9 northward, at a gradient averaging 0 0036 FT/FT declining at an average ' bearing of N 27 deg E
