Unless otherwise noted below, the sample arrived in good condition, and, where required, properly preserved and on ice. The temperature of the cooler at receipt time was 3.0°C General Chemistry Method 350.1: The matrix (MS) recovery for analytical batch 752-4292 was outside control limits for one or more analytes. See QC Sample Results for detail. Sample matrix interference and/or non -homogeneity are suspected because the associated laboratory control sample (LCS) recovery is within acceptance limits. Method 351.2: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 680-796154 and analytical batch 680-796506 were outside control limits for one or more analytes. See QC Sample Results for detail. Sample matrix interference and/or non -homogeneity are suspected because the associated laboratory control sample (LCS) recovery is within acceptance limits. Method 365.4: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 680-796154 and analytical batch 680-796507 were outside control limits for one or more analytes. See QC Sample Results for detail. Sample matrix interference and/or non -homogeneity are suspected because the associated laboratory control sample (LCS) recovery is within acceptance limits. Method SM5210B_Calc: The method blank result associated with batch 752-4330 was higher than the method -required limit of 0.2 mg/L. Method SM5210B_Calc: The correction factor for the Seeded Control Blank (SCB) for batch 752-4330 was outside the method range of 0.6 to 1.0 mg/L. Thus, there is added uncertainty for the associated sample results. No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. Biology No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
