CAM Metals in Soil-EPA Method 6010B and Mercury in Soil EPA Method 7470 <br /> Holding Times <br /> Soil samples a six month and 28days holding times for metals and a 28 day for mercury. <br /> All samples were analyzed with in this time period. <br /> Method Blanks <br /> Method blanks were analyzed with the samples. The blanks were contaminant free. <br /> Sensitivity <br /> No dilutions were necessary therefore the target RLs were achieved. <br /> Matrix Spike/Matrix Spike Duplicate <br /> The MS/MSDs 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 LCSs for these elements were within the control limits <br /> therefore,the results are acceptable. <br /> Laboratory Control Sample <br /> The LCS was prepared and analyzed the same dates as the samples. The LCS results <br /> were within the control limits for% recoveries as stated by Calscience. <br /> Duplicate Samples <br /> One sample was collected twice to determine the consistency of sampling. <br /> Analyte Sample# Result Dup.
