Erik Gessert is the Supervisor of the Petroleum Remediation Program for the Colorado Division of Oil and Public Safety and has worked for the State of Colorado since 2010. In this role Erik has focused on incorporating state of the science technologies into the program, including green and sustainable practices, advanced characterization techniques and conceptual site model developments. Additionally, with Erik's involvement, the Petroleum Program has placed emphasis on the utilization of SMART goals to address environmental concerns. Prior to joining the State, Erik worked as an environmental consultant specializing in petroleum remediation and was responsible for managing projects and budgets, performing technical evaluations and implementing corrective action plans. He earned a bachelor's degree in Environmental Engineering (with a minor in Environmental Studies) from the University of Wisconsin-Madison in 2001. Erik obtained his Professional Engineering license from the State of Colorado in 2007.



Since 2007, ITRC has been a national leader in producing technical and regulatory guidance documents and training courses on light non-aqueous phase liquids (LNAPL).

These efforts have been instrumental in:

  • Advancing modern LNAPL site conceptual models;
  • Identifying specific LNAPL concerns and addressing them through the use of LNAPL saturation and composition-based remedial objectives;
  • Selecting established LNAPL remedial technologies to achieve remedial objectives; and
  • Implementing remedial technologies to achieve quantifiable goals and endpoints.

The LNAPL courses provided by ITRC have trained over 18,000 participants since 2009.

In 2016, the ITRC LNAPL team took on the task of developing a comprehensive web-based guidance that captures the fundamentals presented in the original documents, while also incorporating new science and enhanced understandings that have emerged since the original documents were published.

This workshop will provide an update on the team's efforts and will include focused tutorials on the LNAPL Conceptual Site Model, Natural Source Zone Depletion and relevant remedial technology selection case studies.
