Case Narrative EnSafe Lot Number: PA16008 SC DHEC No: 32010 NC Field Parameters No: 5639 NELAC No: E87653 NC DENR No: 329 This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary following this Case Narrative. The sample receiving date is documented in the header information associated with each sample. All results listed in this report relate only to the samples that are contained within this report. Sample receipt, sample analysis, and data review have been performed in accordance with the most current approved NELAC standards, the Shealy Environmental Services, Inc. ("Shealy") Quality Assurance Management Plan (QAMP), standard operating procedures (SOPs), and Shealy policies. Any exceptions to the NELAC standards, the QAMP, SOPs or policies are qualified on the results page or discussed below. If you have any questions regarding this report please contact the Shealy Project Manager listed on the cover page. GC/MS Volatiles The MS/MSD associated with sample -007 had cis-1,2-dichloroethene, tetrachloroethene, trichloroethene and vinyl chloride recovered outside of the acceptance limits. The LCS/LCSD were recovered within the required acceptance limits; therefore, this demonstrates a matrix effect and data quality is not impacted. Inorganic Metals The method blank associated with sample -012 had dissolved lead detected at a concentration that was above the MDL but below ½ the PQL. All samples associated with this method blank that have detections for dissolved have been flagged with a "B". The method blank associated with samples -011, -012 and -013 had total lead detected at a concentration that was above the MDL but below ½ the PQL. All samples associated with this method blank that have detections for lead have been flagged with a "B". The MS/MSD associated with sample -007 had total and dissolved arsenic, barium, cadmium, chromium, iron, lead, magnesium, manganesee, potassium, selenium and silver recovered outside of the acceptance limits. The LCS/LCSD were recovered within the required acceptance limits; therefore, this demonstrates a matrix effect and data quality is not impacted. Inorganic Non-Metals The method blank associated with sample -009 had sulfate detected at a concentration that was above the MDL but below ½ the PQL. All samples associated with this method blank that have detections for sulfate have been flagged with a "B". The MS/MSD associated with sample -007 had alkalinity recovered outside of the acceptance limits. The LCS/LCSD were recovered within the required acceptance limits; therefore, this demonstrates a matrix effect and data quality is not impacted. The MS/MSD associated with sample -007 had chloride recovered outside of the acceptance limits. The LCS/LCSD were recovered within the required acceptance limits; therefore, this demonstrates a matrix effect and data quality is not impacted. The MS/MSD associated with sample -007 had sulfate recovered outside of the acceptance limits. The LCS/LCSD were recovered within the required acceptance limits; therefore, this demonstrates a matrix effect and data quality is not impacted. Sample -004 was diluted 5x for sulfate analysis due to matrix interference. The reporting limit has been raised accordingly. Samples -005, -006 and -007 were diluted 50x for chloride and sulfate analysis due to matrix interference. The reporting limits have been raised accordingly.
