Surrogate Spike Recovery <br /> The surrogate %recoveries were within the control limits as indicated in the report <br /> provided by Calscience. <br /> Matrix Spike,Matrix Spike Duplicate, the Relative Percent Differences, <br /> The MS and MSD were analyzed with the sample and the percent recoveries and the <br /> RPDs were within the control limits. <br /> Laboratory Control Sample <br /> LCS samples were analyzed with the sample batch and were within control limits as <br /> stated by Calscience. The LCS was prepared with the samples and was in the same batch <br /> analyzed on the same day. <br /> CAM Metals in Soil-EPA Method 6010B and Mercury in Soil EPA Method 7470 <br /> Holding Times <br /> Soil samples have six month holding time for metals and a 28 days for mercury. The <br /> sample was analyzed within this time period. <br /> Method Blanks <br /> Method blanks were analyzed with the sample. The blank was contaminate free of all <br /> analytes. <br /> Sensitivity <br /> No dilutions were necessary therefore the target RLs were achieved. <br /> Matrix Spike/Matrix Spike Duplicate <br /> The MS/MSD were analyzed with the samples. The MS and MSD % recoveries and the <br /> RPDs were within the control limits except for antimony, molybdenum, aluminum, iron, <br /> magnesium and manganese. The LCS for these elements were within the control limits. <br /> The results are acceptable. <br /> Laboratory Control Sample <br /> The LCS was prepared and analyzed the same dates as the sample. The LCS results were <br /> within the control limits for%recoveries for all analytes as stated by Calscience. <br /> 16 <br />
