They are waters with sediment. <br /> All other samples were received in good condition within temperature requirements. <br /> GC/IBIS VOA <br /> Method(s)8260B/CA_LUFTMS: The Gasoline Range Organics(GRO)concentration reported for the following sample(s) is due to the <br /> presence of discrete peaks: B-1 (720-21697-13). <br /> Method(s)8260B/CA_LUFTMS:The Gasoline Range Organics(GRO)concentration reported for the following sample(s) is due to the <br /> presence of discrete peaks: B-2(720-21697-14). <br /> Method(s)8260B/CA_LUFTMS:The Gasoline Range Organics(GRO)concentration reported for the following sample(s)is due to the <br /> presence of discrete peaks: B-1 (720-21697-13). <br /> Method(s)8260B/CA_LUFTMS: The laboratory control sample(LCS/LCSD)for preparation batch#55238 exceeded control limits for the <br /> following analytes: C5-C12. These analytes were biased high in the LCS/LCSD and were not detected in the associated samples; <br /> therefore,the data have been reported. <br /> Method(s)8260B: Recovery for 2-hexanone is high and acetone recovery is low. <br /> Method(s)8260B: 2-hexanone recovery is high. <br /> No other analytical or quality issues were noted. <br /> GC VOA <br /> No analytical or quality issues were noted. <br /> Page 2 of 63 08/17/2009 <br />
