cbCurtis &Tompkins, Ltd, <br /> CASE NARRATIVE <br /> Laboratory number: 218019 <br /> Client: Oneida Total Integrated Enterprises <br /> Project: 2009069 <br /> Location: CA ARNG - LODI <br /> Request Date: 01/28/10 <br /> Samples Received: 01/28/10 <br /> This data package contains sample and QC results for one soil sample, <br /> requested for the above referenced project on 01/28/10. See attached cooler <br /> receipt form for any sample receipt problems or discrepancies. <br /> TPH-Extractables bV GC (EPA 8015B) : <br /> No analytical problems were encountered. <br /> Volatile Organics bV GC/MS (EPA 8260B) : <br /> Low response was observed for bromomethane in the ICV analyzed 02/05/10 <br /> 01:17; this analyte was not detected at or above the RL in the associated <br /> samples. <br /> Matrix spikes were not performed for this analysis in batch 159914 because <br /> matrix or site history indicated the recoveries would be non-meaningful. <br /> LODI-WC-01 (lab # 218019-001) was diluted due to high hydrocarbons. <br /> No other analytical problems were encountered. <br /> Pesticides (EPA 8081A) : <br /> All samples underwent sulfur cleanup using the copper option in EPA Method <br /> 3660B. <br /> All samples underwent florisil cleanup using EPA Method 3620C. <br /> Low responses were observed for many analytes in the ICV analyzed 12/06/09 <br /> 20:28. <br /> Low response was observed for heptachlor epoxide in the ICV analyzed 02/01/10 <br /> 18:03; average ICV drift met method requirements. <br /> High responses were observed for dieldrin, endosulfan II, and methoxychlor in <br /> the CCV analyzed 02/04/10 21:35; average CCV drift met method requirements, <br /> and these analytes were not detected at or above the RL in the associated <br /> sample. <br /> High responses were observed for dieldrin and methoxychlor in the CCV <br /> analyzed 02/05/10 00:12; average CCV drift met method requirements, and these <br /> analytes were not detected at or above the RL in the associated sample. <br /> High responses were observed for a number of analytes in the CCV analyzed <br /> Page 1 of 2 <br /> 33.o <br /> 2 of 295 <br />
