Canonie Environmental Case Narrative <br /> Client : ENVIRONMENTAL SOLUTIONS Project # : L90076 <br /> LP # . 9862 <br /> Inorganics Case Narrative <br /> Total metals analyses completed in accordance with SW 846 <br /> protocol _ <br /> volatiles Case Narrative <br /> Sample analysis met SW-846 QC criteria. <br /> Calibration was verified for all samples _ <br /> Surrogate recoveries were within acceptable limits . <br /> The method blank associated with this group of samples was <br /> free from target analyte interferences at, or above, the <br /> reporting limits. <br /> Spike recoveries were within acceptable limits . <br /> Pesticides Case Narrative <br /> TEH: Calibration was verx,fied for all samples analyzed. The <br /> method Blank was free from interferences at or above the <br /> reporting limits . Interferences in sample REMOTE FILL <br /> (855331) exceeded the spike concentration and required a <br /> dilution for analysis which qualifies any recovery data_ <br /> PCB: Calibration was verified for all samples analyzed. The . <br /> Method Blank was free from interferences at or above the re- <br /> porting limits . The presence of AR1254 in sample SD-C3 (R) <br /> COMP exceeded the spike concentration and required a dilu- <br /> tion for analysis, which qualifies any recovery data. Sam- <br /> ple ST--3A showed the presence of low level, PCB-like peaks, <br /> but did not match any known Aroclor patterns_ <br /> Extractions Pest. Case Narrative <br /> EPCB-S <br /> All samples were extracted within the required holding times <br /> using method 3550 . An acid clean--up was performed on all <br /> samples and the blank to remove interferences . A TBA <br /> clean-up was performed on all samples and the blank to <br /> remove sulfur compounds. <br /> TEH: All samples were extracted within the required holding <br /> time by Method 3550 . <br /> 0 <br /> CanonleE nv 1 ronmental <br />
