Emergency Response for Crude Oil Pipeline Release

Emergency Response for Crude Oil Pipeline Release

Incident Management Support


A major oil and gas company contacted Antea Group to support them in responding to a pipeline spill of 20,600 barrels of crude oil in a wheat field in the central plains of the United States.

Challenges included an aggressive schedule, investigating the extent of the release and identifying and selecting a thermal desorption unit (TDU) contractor, and overseeing the excavation of over 1,000,000 CY of soil. 

Our scope of work included:

  • Subsurface investigation using laser induced florescence, Geoprobe and sonic soil boring equipment
  • 3D mapping of spill using ArcGIS
  • Monitoring/production well installation oversight
  • Request for Bid package to TDU contractors
  • Soil sampling program for monitoring excavation and thermal treatment
  • Reporting and developing clean up goals for the NDDH
  • Soil and groundwater assessment
  • Long-term groundwater monitoring


Antea Group’s role was to investigate the extent of the release and to support the TDU contractor in identifying soil to be treated. Several contractors were used to complete the scope of work. 

Services provided by Antea Group included preparing procurement plans and bid documents for the TDU, contracting, coordination, safety support, permitting support, field oversight, air monitoring, quantity tracking and reporting.


The excavation and thermal treatment began in June 2014.  The thermal treatment portion of the project is expected to be completed by Summer 2017. 

Quantities of crude oil impacted soil to be removed: 750,000 tons. After the treated soil is returned to the excavation, clean topsoil will placed over it and the site restored to agricultural use.
