State Department of Environment and Natural Resources LUST/TRUST Cleanup Bison, South Dakota

State Department of Environment and Natural Resources LUST/TRUST Cleanup Bison, South Dakota

A contractor encountered petroleum impacted soils during storm sewer excavation in Bison, SD. AET was brought in by the South Dakota Department of Environment and Natural Resources (SD DENR) to observe the removal of petroleum contaminated soils and arrange for proper disposal during the sewer installation. Subsequent subsurface investigations for the SD DENR helped delineate the extent of the contamination. We identified four nearby release sources and prepared corrective action recommendations.

By getting involved early, AET helped to keep the project on schedule for the contractor and client by screening soils during excavation and arranging contaminated soil disposal alternatives. We also helped identify the contamination sources so they could be addressed to prevent future petroleum contamination spreading in the area, supporting SD DENR oversight.

AET Petrography Webinar

Forensic Geology/Petrography: What Aggregate Analyses Tell Us About Concrete

1/26/2022, 11:30 AM - 12:30 PM CST

AET takes you inside an examination of aggregates and concrete to understand the standards, cover typical observations, and review past projects.

We’ll also answer these questions and many others:

  • Does AET use XRD?
  • Are there methods for detecting problem minerals (like pyrrhotite) using GIS?
  • Can deleterious materials in aggregates lead to court cases?
  • Besides the ASTM standards, what other references does AET recommend for aspiring material petrographers?

The AET Petrography Webinar is presented by ​​Chris Braaten, PG, CPG, a Senior Petrographer/Geologist at American Engineering Testing, Inc. Chris has performed petrographic analysis on construction aggregates from 49 US States and 18 different countries/territories.
