* STLC and TCLP extractions require 2 days to complete; therefore, all TATs begin after the extraction is completed (i.e., One-day TAT yields results in 3 days from sample submission).

NOTES:
- MAI assumes that all material present in the provided sampling container is considered part of the sample - MAI does not exclude any material from the sample prior to sample preparation unless requested in writing by the client.

* STLC and TCLP extractions require 2 days to complete; therefore, all TATs begin after the extraction is completed (i.e., One-day TAT yields results in 3 days from sample submission).

a2 Sample diluted due to cluttered chromatogram.
a3 Sample diluted due to high organic content interfering with quantitative/or qualitative analysis. a4 Reporting limits raised due to the sample's matrix prohibiting a full volume extraction. c1 Surrogate recovery outside of the control limits due to the dilution of the sample. c2 Surrogate recovery outside of the control limits due to suspected matrix interference. d7 Strongly aged gasoline or diesel range compounds are significant in the TPH(g) chromatogram. e2 Diesel range compounds are detected; no recognizable pattern. e7 Oil range compounds are detected.
h7 Copper (EPA 3660B) cleanup.
j1 See attached narrative.

Quality Control Qualifiers
F1 MS/MSD recovery and/or RPD is out of acceptance criteria; LCS validates the prep batch.

F5 LCS/LCSD recovery is outside of acceptance limits; however, the data is acceptable based upon the TNI allowable marginal exceedances.

F10 MS/MSD outside control limits. Physical or chemical interferences exist due to sample matrix.

Total Extractable Petroleum Hydrocarbons- Diesel, Motor Oil Sample 2208D63-009A was analyzed on an instrument sequence with a passing closing continuing calibration verification (CCV) that was analyzed outside of the method recommendation of a 12-hour time frame due to tower error that stopped the sequence prior to its completion. The CCV recoveries were within control limits both before and after the tower error; therefore, there is no impact to the results. The quality of the data is acceptable and reportable.

* STLC and TCLP extractions require 2 days to complete; therefore, all TATs begin after the extraction is completed (i.e., One-day TAT yields results in 3 days from sample submission).

U** = An unpreserved container was received for a method that suggests a preservation in order to extend hold time for analysis. - Organic extracts are held for 40 days before disposal; Inorganic extract are held for 30 days.
