Notes and Definitions
QM-4X The spike recovery was outside of QC acceptance limits for the MS and/or MSD due to analyte concentration at 4 times or greater the spike concentration. The QC batch was accepted based on LCS and/or LCSD recoveries within the acceptance limits.
HT-F This is a field test method and it is performed in the lab outside holding time.
HT-B2 The remaining holding time was less than an hour when the sample was received at the laboratory. Therefore, it was analyzed outside the holding time.
HT-1 The sample was received outside of the EPA recommended holding time.
Sample results reported on a dry weight basis

Notes and Definitions
QM-4X The spike recovery was outside of QC acceptance limits for the MS and/or MSD due to analyte concentration at 4 times or greater the spike concentration. The QC batch was accepted based on LCS and/or LCSD recoveries within the acceptance limits.
J Detected but below the Reporting Limit; therefore, result is an estimated concentration.
HT-1 The sample was received outside of the EPA recommended holding time.
Sample results reported on a dry weight basis

Notes and Definitions
QM-4X The spike recovery was outside of QC acceptance limits for the MS and/or MSD due to analyte concentration at 4 times or greater the spike concentration. The QC batch was accepted based on LCS and/or LCSD recoveries within the acceptance limits.
J Detected but below the Reporting Limit; therefore, result is an estimated concentration.
Sample results reported on a dry weight basis
