Quality Assurance Manager Heath Low


TerraGraphics Environmental Engineering, Inc. (TerraGraphics) Quality Assurance (QA) Program continues to implement Nuclear Quality Assurance (NQA-1) and broaden business opportunities by providing clients with numerous quality-related services.

The QA Team promotes continuous improvement within TerraGraphics quality assurance systems, and hopes to expand TerraGraphics opportunities by improving quality-related procedures and incorporating standards into the daily work flow.  TerraGraphics QA Team hopes to be accredited to use other reputable assessment standards, along with NQA-1, in the near future.

TerraGraphics Quality Program has been surveilled, assessed, and audited to the requirements of NQA-1 by the following companies:

  • Washington River Protection Solutions, LLC,
  • Mission Support Alliance, LLC, and
  • Veolia

For more information about TerraGraphics Quality Assurance Program, please feel free to contact Heath Low, Quality Assurance Manager, NQA-1 Lead Auditor, and CQE at 509-547-3883.

TerraGraphics plays a key role in a project demonstrating the feasibility of using a Mobile Atmospheric Monitoring Laboratory to quantify volatile air contaminants in real time with part per trillion to part per billion detection levels. These results are used in worker Health and Safety investigations. The mobile laboratory contains a Proton Transfer Reaction – Mass Spectrometer (PTR-MS) instrument using Time of Flight (TOF) technology. This work is being done in support of ongoing quantitative measurements of vapor emissions. The project goal is to implement selected vapor monitoring technologies that can be deployed to support plant operations related to real-time short duration vapor release events. TerraGraphics provides Project Management, subject matter expertise utilizing multiple Ph.D. Chemists, project Quality Assurance, and data processing, reduction, and reporting.

As part of the Mobile Lab project, TerraGraphics has assembled a world class team of experts to process, manipulate, deconvolute, and report PTR-MS data. This allows for the rapid reporting of hundreds of chemical compounds with exceptional time resolution at part per trillion levels. Further mathematical workup of this data gives Health and Safety professionals statistical analysis of vapor concentrations, including max/min, means, concentration distributions, and comparison to Occupational Exposure Limits. Advanced data visualization tools are used to plot results in an easily useable form for clients. Using advanced analytical and computing algorithms, data is expressed with spatial and temporal resolution for a variety of chemical constituents at trace levels.
