Respectfully, PRISM LABORATORIES, INC. a,j Angela D. Overcash VP Laboratory Services Data Qualifiers Key Reference: Reviewed By Terri W. Cole For Angela D. Overcash Project Manager A Recovery of Low -Level ICV at 0.5 mg/kg (146%) is greater than the upper limit (120%). Result might have a high bias. Aa Recovery of Low -Level ICV at 2.5 mg/kg (96%) is within the control limits (80-120%). CCVH CCV result is above control limits but within method parameters. Result is considered estimated. D RPD value outside of the control limits. J Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLIP J-Flag). L2 LCSD recovery outside of the QC limits. LCS recovery within the limits. No further action taken. LH High LCS recovery. Analyte not detected in the sample(s). No further action taken. M Matrix spike outside of the control limits. MC Sample concentration too high for recovery evaluation. BRL Below Reporting Limit MDL Method Detection Limit RPD Relative Percent Difference * Results reported to the reporting limit. All other results are reported to the MDL with values between MDL and reporting limit indicated with a J.
