We are an international group of geologists representing the consulting, laboratory, and university research fields working toward the goals of addressing:

  • Guidelines for identifying the occurrence, modes of formation and associated host rock types of the various NOA minerals
  • Geological assessment and field sampling methods for NOA in rock and soil
  • Laboratory rock and soil testing sample preparation & analysis protocols (PLM, PCM, TEM, SEM, XRD), including interpretation of EDS chemical analytical data
  • Laboratory calibration standards
  • Guidance in the interpretation and presentation of field data and lab test results
  • Guidelines for the protection of workers and the public from large and small construction projects
  • Training and certification programs for geologists, analysts, construction project designers, field supervisors, construction workers, and others to ensure expertise on NOA-related issues

Group History

We initially formed as a collaborative group of geologists and industrial hygienists as an Association of Environmental & Engineering Geologists (AEG) Technical Working Group. Since 2012, we have hosted six NOA Symposiums, multiple dinner meetings, and field trips in California, Nevada, and North Carolina.

Following the our symposium, held in 2018 as part of the International Association for Engineering Geology and the Environment (IAEG) Congress / AEG Annual Meeting, we formed an IAEG Commission on NOA.

This website serves the purpose of relaying information about our research and policy efforts to interested scientists.
