Batch: LBA-897475 Volatiles by SW 8260B<br />

N1:<br />

2,2-Dichloropropane recovered above acceptance criteria in the LCS/LCSD and MS/MSD. This<br />

equates to a potential high bias. Since the associated field samples were non-detect for 2,2-<br />

Dichloropropane, no further action was required<br />

R2:<br />

The RPD for Trichlorofluoromethane was above acceptance criteria in the MS/MSD pair. Since<br />

the recovery and RPD for Trichlorofluoromethane were within criteria in the LCS/LCSD, no<br />

further action was required.<br />

Batch: LBA-897521 TPH by SW 8015AZ R.1<br />

S10:<br />

Due to matrix interference, the surrogate recovered above acceptance criteria.<br />
