Sampling at the Thermal Treatment Unit (TTU), Technical Area III

LOCATION: ALBUQUERQUE, NEW MEXICO

CLIENT: SANDIA NATIONAL LABORATORIES

The scope of work for this task was to conduct soil sampling at the Technical Area (TA) III Thermal Treatment Unit (TTU) in accordance with the New Mexico Environment Department (NMED) Hazardous Waste Facility Permit No. NM580110518. The TTU is operated in accordance with the requirements of the permit. Section 5.9 of the permit requires the collection of soil samples at 11 specified locations during certain years of the 10-year permit term.  

BGI conducted pre-planning activities including updating the activity hazard analysis and abbreviated Health and Safety Plan (H&S) addendum to cover field activities planned under this task order. In addition, BGI field personnel obtained the required facility and site-specific training prior to field mobilization. BGI also prepared a project-specific schedule for Sandia National Laboratories (SNL) review and approval during the project planning phase.  

BGI collected unconsolidated soil samples at 11 locations. The scope of work included collection of soil samples from the surface and at 2 feet below ground surface at each of 11 sample locations. Soils samples were collected using clean sampling spoons and a hand auger. Soil samples from all locations were analyzed for silver, semi-volatile organic compounds (SVOCs), polynuclear aromatic hydrocarbons (PAHs), and dioxins/furans. Once sampling was completed and all equipment had been removed from the sample location, soil cuttings were utilized to backfill the sample borehole. Cuttings were compacted and the area was re-graded to match existing grade. Soil sampling was performed in strict accordance with the field work plan and followed SNL/NM Sample Management Office (SMO) procedures and protocols.   

BGI maintained all required records associated with the sampling activities. Field records were submitted to and maintained by the SNL/NM Customer Funded Records Center. Following completion of the project, a report was prepared for field activities. The report contained a narrative describing work performed and any variances to the field work plan.
