Page 2 of 2 <br /> This is an important area because it is the area of highest reported contamination in the soil, really high.VW-2 <br /> needs to be sampled. I see Margaret did not mention this well in her 7121/09 letter, I don't know why but I will <br /> address this in a follow up modification letter. Next semi-annual should be in July, hopefully we can get this <br /> straightened out by then. <br /> Also, I am concerned about that soil data. The numbers were so very high in those three borings, and it does not <br /> appear any confirmation borings were done. Unfortunately, the ozone sparge points were put in without even <br /> logging, much less sampling. I haven't discussed it with our geologist yet, but I think we may need to do a <br /> confirmation boring in that area, to ensure there is no continuing source of contamination leeching into the GW. <br /> would appreciate any comments... <br /> Lori <br /> Lori Duncan, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> Idu ncan(o,s iceh d.com <br /> (209)468-0337 phone <br /> (209)468-3433 fax <br /> 4/2/2010 <br />
