CASE NARRATIVE SUMMARY
All reported results are within defined laboratory quality control objectives unless listed below or otherwise qualified in this report.
[TOC_1]Case Narrative[TOC]
SM21-23 6200B
Qualifications:
Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits. Data validation is not
affected since all results are "not detected" for associated samples in this batch and bias is on the high side.
Analyte & Samples(s) Qualified:
L-02
1,1-Dichloroethylene
B324776-BS1, B324776-BSD1
Chloromethane
B324776-BS1, B324776-BSD1
Dichlorodifluoromethane (Freon 12)
B324776-BS1, B324776-BSD1
Ethanol
B324776-BS1, B324776-BSD1
Vinyl Chloride
B324776-BS1, B324776-BSD1
Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but the other is within limits. RPD
between the two LFB/LCS results is within method specified criteria.
Analyte & Samples(s) Qualified:
L-07
Trichlorofluoromethane (Freon 11)
B324776-BS1
Laboratory fortified blank duplicate RPD is outside of control limits. Reduced precision is anticipated for any reported value for this
compound.
Analyte & Samples(s) Qualified:
R-05
Bromomethane
22L0269-01[MW-1], 22L0269-02[MW-2], 22L0269-03[MW-4], 22L0269-04[MW-6], 22L0269-05[WSW-1], 22L0269-06[Thomas WSW], 22L0269-07[Metcalf WSW],
22L0269-08[FB], 22L0269-09[TB], B324776-BLK1, B324776-BS1, B324776-BSD1
The results of analyses reported only relate to samples submitted to the Con-Test Analytical Laboratory for testing.
I certify that the analyses listed above, unless specifically listed as subcontracted, if any, were performed under my direction according to the approved methodologies listed
in this document, and that based upon my inquiry of those individuals immediately responsible for obtaining the information, the material contained in this report is, to the
best of my knowledge and belief, accurate and complete.

*QC result is outside of established limits.
Wide recovery limits established for difficult compound.
Wide RPD limits established for difficult compound.
#Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
No results have been blank subtracted unless specified in the case narrative section.
FLAG/QUALIFIER SUMMARY
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits.
Data validation is not affected since all results are "not detected" for associated samples in this batch and bias is
on the high side.
L-02
Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but
the other is within limits. RPD between the two LFB/LCS results is within method specified criteria.
L-07
Laboratory fortified blank duplicate RPD is outside of control limits. Reduced precision is anticipated for any
reported value for this compound.
R-05
