CASE NARRATIVE

Client: ARCADIS U.S., Inc.

Project: 2018 Annual GW Sampling DSCR-OU7

Report Number: 680-151147-2

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 04/14/2018; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was 0.5º C, 0.7º C, 0.8º C, 1.0º C, 1.0º C, 1.2º C, 1.2º C, 2.0º C, 2.1º C, 2.1º C, 2.1º C, 2.9º C and 3.5º C.

Qualifiers

GC/MS VOA

Qualifier Description

U Undetected at the Limit of Detection.

Qualifier

J Estimated: The analyte was positively identified; the quantitation is an estimation

Q One or more quality control criteria failed.

M Manual integrated compound.

J1 Estimated: The quantitation is an estimation due to discrepancies in meeting certain analyte-specific quality control criteria.

D The reported value is from a dilution.

H Sample was prepped or analyzed beyond the specified holding time

4 MS, MSD: The analyte present in the original sample is greater than 4 times the matrix spike concentration; therefore, control limits are not applicable.

GC/MS Semi VOA

Qualifier Description

U Undetected at the Limit of Detection.

Qualifier

M Manual integrated compound.

Q One or more quality control criteria failed.
