Former Unocal/Wards - 3 - 23 February 2005 ' <br /> 5400-5606 Pacific Ave., Stockton ' <br /> John said that the ENSR technicians are experiencing chlorinated solvent odors when opening monitoring wells, and ' <br /> asked me if there were any dry cleaners or other possible sources for the smells. I asked ENSR to contact their <br /> laboratory and look at the chromatographs for the EPA Method 9260B to identify possible Tentatively Identified <br /> Compounds (TICs), and report any TICS for chlorinated solvents to me. I mentioned the 6600 block of Pacific Ave as ' <br /> an active tetrachloroethylene(PCE) groundwater cleanup site(Lincoln Center),and added that Lincoln Center is over <br /> a mile to the north of their site, but that there are sewers extending along Pacific Avenue. John suggested that there <br /> might be a connection due to vapor intrusion through soil. I suggested that ENSR set up a file review of Lincoln ' <br /> Center at our office. Subsequently in a conversation with Mike Infuma, SJCEHD on 7 February 2005, he identified a <br /> potential former dry cleaner facility adjacent to Unocal. David Stavarek of my office suggested using Draager tubes <br /> for verification of gases when opening well caps. On 10 February 2005 Mike Infurna and I visited the One Hour ' <br /> Martinizing at 5756 Pacific Ave. The proprietress stated that they had stopped using PCE over 4 years ago. <br /> The meeting ended at 1440 hours.
