(Adjustment <br /> for Daylight Saving is not accounted.) <br /> WET(STLC) Waste Extraction Test(Soluble Threshold Limit Concentration) <br /> Analytical Qualifiers <br /> S Surrogate recovery outside accepted recovery limits. <br /> a4 Reporting limits raised due to the sample's matrix prohibiting a full volume extraction. <br /> a14 Reporting limit raised due to the physical nature of the sample. <br /> cl Surrogate recovery outside of the control limits due to the dilution of the sample. <br /> c2 Surrogate recovery outside of the control limits due to suspected matrix interference. <br /> e2 Diesel range compounds are detected; no recognizable pattern <br /> Quality Control Qualifiers <br /> F2 LCS/LCSD recovery and/or RPD/RSD is out of acceptance criteria. <br /> F5 The LCS/D result fell below the lower control limit but remained within the marginal exceedance range.The <br /> associated sample result(s)yielded a non-detect and potentially biased low;therefore the result is considered <br /> estimated. <br /> F7 The LCS/LCSD recovered above the upper control limit but within marginal exceedance limit per TNI guidance. <br /> The result(s)is reported as a high estimate for the compound(s) indicated. <br /> Page 3 of 36 <br />
