CASE NARRATIVE

Client: MWH Americas Inc

Project: MWH - Boeing SSFL GW 1Q15

Report Number: 280-64994-1

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 some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples,

the reporting limits are adjusted relative to the dilution required.

Calculations are performed before rounding to avoid round-off errors in calculated results.

All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the

individual sections below.

RECEIPT

The samples were received on 2/4/2015 10:00 AM; the samples arrived in good condition, properly preserved and, where required, on

ice. The temperatures of the 4 coolers at receipt time were 1.1 C, 2.8 C, 3.9 C and 5.9 C.

The requested 1,2,3-TCP 524.2 SIM, and 314.0_LL Perchlorate analyses were performed by TestAmerica's Irvine laboratory.

The requested 8315 Formaldehyde analyses were performed by TestAmerica's North Canton laboratory.

The samples requesting "Extract and Hold" on the Chain of Custody will be reported under a separate cover (280-64994-2). All other

samples/analyses requested on the Chain of Custody will be found in this report.

The volume submitted for 314 Perchorate analysis for sample RD-78_020315_01 (280-64994-11) was received with approximately 1/4

inch of headspace. For water samples, headspace should be about one-third of the container in order to reduce potential anaerobic

biodegradation.

VOLATILE ORGANIC COMPOUNDS (GC/MS SIM) - 524.2 SIM

Sample RD-60_020315_01 (280-64994-5)[2.5X] required dilution prior to analysis. The reporting limits have been adjusted accordingly.

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

VOLATILE ORGANIC COMPOUNDS (GC-MS)

Methylene Chloride was detected in method blank MB 280-263200/8 at a level that was above the method detection limit but below the

reporting limit. The value should be considered an estimate, and has been flagged. If the associated sample reported a result above the

MDL and/or RL, the result has been flagged.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

VOLATILE ORGANIC COMPOUNDS (GC-MS SIM)

1,4-Dioxane exceeded the RPD limit for LCSD 280-263242/4. The associated LCS/LCSD spike recoveries were in control and

demonstrate that operating procedures were in control. No further action was required.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

SEMIVOLATILE ORGANIC COMPOUNDS (GC-MS)

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

SEMIVOLATILE ORGANIC COMPOUNDS - GC/MS SIM LL

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

GAS RANGE ORGANICS

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

DIESEL RANGE ORGANICS

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

PERCHLORATE (IC) - 314.0_LL

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

FORMALDEHYDE

Formaldehyde was detected in method blank MB 240-166845/2-A at a level exceeding the reporting limit. If the associated sample

reported a result above the MDL and/or RL, the result has been flagged.

02/18/2015Page 3 of 101

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

PERCHLORATE - 6860

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

ANIONS (48 HOURS) - Nitrate as NO3

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

ANIONS (28 DAYS) - Fluoride

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

AMMONIA

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

CORROSIVITY (PH)

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

HYDRAZINE/UDMH/MMH

1,1-dimethylhydrazine (or unsymmetrical dihydrazine, UDMH)- eluted outside the retention time window on the matrix spike or matrix

spike duplicate for the following samples and parent samples: (280-64994-6 MS), (280-64994-6 MSD), RD-39B_020315_01

(280-64994-6). When reviewing the samples for target compounds, this retention time shift was taken into account. Individual samples

were compared to neighboring QC as well as individual matrix retention time spikes.

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
