I have received and reviewed the Transmittal of Sample Analysis Results for the above-referenced Analytical Services Request(ASR) and have indicated my findings below by checking~6TTe of the boxes for Data Disposition.

I understand all samples will be disposed upon receipt of this form, unless samoles are requested to be held. If I do not return this form all samples will be disposed of on AUG L U ^"13

• "RELEASED" - Read-only to all Region 7 employees and contractors that have R7LIMS "Customer" account. All Samples may be disposed of upon receipt of this form if not requested to be held.

• "Project Manager Accessible" - Available on the LAN in R7LIMS for my use only. All Samples may be disposed of upon receipt of this form if not requested to be held.

• "Archived" - THIS DATA IS OF A SENSITIVE NATURE. Any future reports must be requested through the laboratory. All samples may be disposed of upon receipt of the form if not requested to be held.

• Hold Samples - I have determined that the samples need to be held until —— after which time they will be disposed of in accordance with applicable regulations. The reason for the hold is:

• Samples are associated with a legal proceeding.

• Question/Concern with data - possible reanalysis requested.

Analysis Comments About Results For This Analysis

1 VOCs in Air at Ambient Levels by GC/MS

Lab: RASP Contract Lab (Out-Source)

Method: Similar to EPA Region 7 RLAB Method 3230.4G (see comments)

Samples: 1- 1-FD 2- 3- 4- 5- 6-7- 8- 9- 10-_ 12- 13- 14-14-FD 15-

Comments: The pressure of the sample canisters was checked prior to analysis. The pressures ranged from 6.9 to 14.7 psia. Sample 6787-14FD was received at 6.9 and required pressurization for analysis which resulted in an initial dilution.
