Post : <br /> This letter is in response to your request for GHH <br /> Engineering to provide site investigation services at the <br /> subject, site . <br /> GHH Engineering, Inc . was contacted on November 7, 1988 by <br /> Port & Co . to conduct soil sampling following the removal of <br /> an 8 , 000-gallon diesel tank at the subject site . Mr . Ed <br /> Childers was present for the tank removal which took place <br /> November 9, 1988 . However, due to the presence of a concrete <br /> pad at the bottom of the excavation and lack of equipment to <br /> out through the concrete, the sampling was postponed . Ms . <br /> Heidi Hubbard was present for the sampling which took place <br /> on November 15, 1988 . Mr . Harlan Knowle of the San Joaquin <br /> County Environmental Health Department was also present to <br /> direct sample acquisition . <br /> Mr . Knowle requested five confirmation samples, three from <br /> the excavation and two from the product line . At the time of <br /> the sampling, the concrete pad had been cored in three places <br /> to allow access to the soil . Sampling was accomplished using <br /> a drive sampler at the locations shown on the attached <br /> figure . The samples were transported under chain of custody <br /> to the laboratories of American Environmental Management <br /> Corporation and analyzed for Total Petroleum Hydrocarbons <br /> (TPH ) and Benzene, Toluene, Ethyl benzene, and Xylenes <br /> (BTEX ) <br /> The analytical results indicate levels of TPH and BTEX below <br /> reporting limits with the exception of the sample taken at <br /> the iF-asL end of the excavation . This sample showed levels of <br /> BTEX at or slightly above reporting limits . Copies of the <br /> ia't) .results are attached . At this time, further investigation <br /> ie, net anticipated .
