Eric Nichols, Principal and founder of Substrata LLC, brings expertise in subsurface contamination and remediation issues to public and private clients worldwide. Mr. Nichols has 30 years of experience in groundwater flow and chemical migration, management and remediation of LNAPL sites, complex contaminant mixtures, modeling methods applied to groundwater and soil restoration, attenuation of chemicals in the subsurface, vapor intrusion characterization and mitigation, groundwater management, and aquifer hydraulics. Through careful application of innovative site characterization strategies and a thorough understanding of regulatory frameworks, Nichols has led the development of consensus-based conceptual site models to manage risks on a wide variety of projects, including upstream and downstream petroleum sites, releases of PFAS, chlorinated solvents, pesticides, metals, radionuclides, and many other chemicals. A lifelong promoter of best practices and a professional educator, Nichols is an acclaimed speaker and teacher in his specialty areas.



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.
