• ' 3.2 Brine Consideration Complete characterization at the site has not yet been achieved The low levels of diesel grade petroleum hydrocarbons may not pose a threat of regulatory significance ' Groundwater is suspect due to the overlapping Victor Meat contamination up gradient The meat packing site was identified as a mayor source of salt brine pollution, resulting in closing down of the surrounding water wells The brine contamination has not been tested in this site's investigation It may be either underlying or very close to the WO&S ' site The Victor Meat Company property is within 500 feet up gradient of the WOS Acampo Plant Site The Victor Meat MW-3A , monitors the shallow water zone (within 70 FT bgs and is within 200 yards upgradient from the WOS site The closest apparent well down gradient is at least 450 FT from the NE corner of the site Isoplaths developed earlier in support of the Victor Meat effort indicate high salinity in the uppermost "Zone A" Elevated specific conductivity readings during Barber's sampling of MW-1 indicate continued high salinity of the same water stratum in which the petroleum hydrocarbons ' were found During future water sampling, testing for total dissolved solids (TDS) may be employed to further identify impact from the brine ' 3.3 Neighboring Property The perimeter of the contamination has not been fully defined and it apparently extends ' onto two neighboring parcels, to the north, an 8 36 AC parcel, APN 017-09-02, to the east by a 14 25 AC parcel APN 017-09-35 owned by Michael and Lisa Douglas since 1998- 1999 Please reference Figure 6, "Assessor's Parcel Map" Additional borings and/or monitoring well installation are anticipated on the neighboring property The landowner's permission is being finalized Verbal agreement is in place and WOS is awaiting written agreement confirmation (as of May 6, 2002) Well Stud 34 W e y ' Per PHSIEHD, Appendix B of the Tri-Regional guidelines calls for a 2,000 FT well survey required for UST site closure Construction details, pumping rates and in some cases exact location may not be readily available Prior to expending engineering ' effort at a cost to the owner, review of surrounding well information collected during the extensive Victor Meat site remediation was carried out at the CVRWQCB's office in ' 3-2
