Receipt All samples were received in good condition within temperature requirements. 8260B Surrogate recovery for the following sample was outside control limits: 23667-5. Evidence of matrix interference is present. Re-analysis was performed with similar results and the sample vial had excessive amounts of sediment. The %RPD of the laboratory control standard (LCS) and laboratory control standard duplicate (LCSD) for preparation batch 660-63772 exceeded control limits due to LIMS calculation for the following analytes: 1,4-Dioxane. The LCSD was double spiked and the %RPD is calculated from the spike concentration, not % recovery. Page 2 of 34 EXECUTIVE SUMMARY - Detections Client: ARCADIS U.S., Inc.
