Project: 2018 Annual GW Sampling DSCR-OU7

Report Number: 680-151095-1

With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In the event of interference or analytes present at high concentrations, samples may be diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required.

RECEIPT

The samples were received on 04/13/2018; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was 0.7º C, 0.9º C, 1.0º C, 1.7º C, 1.9º C, 2.2º C, 2.3º C and 2.9º C.

The data integrity was not impacted and the data has been reported and addressed. All other QC criteria have been met.

The continuing calibration verification (CCV) associated with batch 680-520594 recovered above the upper control limit for

Dichlorodifluoromethane. The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported.

Surrogate toluene-d8 is failing low in the sample. This sample is reporting one analyte from a dilution that quants off of a different ISTD/surrogate. The data has been reported.

OU7-CMT-20-2 (13')_041118 (680-151095-5)

Bromobenzene failed the recovery criteria high for LCSD 680-520422/5. 1,2-Dibromo-3-Chloropropane, 2-Butanone (MEK) and 4-Methyl-2-pentanone (MIBK) exceeded the RPD limit. Refer to the QC report for details.
