Derek Tomlinson Earns ITRC Award for Contributions to DNAPL Site Characterization

Derek Tomlinson, P.E., P.Eng., a senior engineer and hydrogeologist based in Geosyntec's Philadelphia office, has earned the 2012 Industry Recognition Award from the Interstate Technology & Regulatory Council (ITRC) for his contributions to the council's Dense Non-aqueous Phase Liquids (DNAPL) Site Characterization team.

The ITRC's mission is to develop information resources and help break down barriers to the acceptance and use of technically sound, innovative solutions to environmental challenges through an active network of diverse professionals. The council's membership includes state and federal partners, industry participants, and other stakeholders, cooperating to broaden and deepen technical knowledge and streamline the regulation of new environmental technologies.

ITRC technical work teams, such as the DNAPL Site Characterization team, develop guidance documents and training courses to meet the information needs of regulatory staff, technology vendors, and environmental consultants throughout the country. These products help state environmental agencies gain valuable technical knowledge and develop consistent regulatory approaches for reviewing and approving specific technologies.

During the past decade there have been advances in process understanding and development of new technologies relevant to the investigation and remediation of DNAPL sites. The ITRC DNAPL Site Characterization team is developing a complete revision of its 2003 guidance document to present a current understanding of the conceptual site model (CSM) within the source and plume zones, and the multiple phases of DNAPL as well as incorporating objectives-based site characterization.

To this end, Derek is leading the development of a chapter in the new guidance on high resolution site characterization tools within both unconsolidated and bedrock geologies. This chapter will provide users comprehensive information about the tools available to understand the geology, hydrogeology, and chemistry within the zone or phase of interest. The new ITRC DNAPL site characterization guidance document will be a web-based, interactive document with anticipated publishing in 2014.

Geosyntec is well represented on the ITRC DNAPL Site Characterization team, which also includes Principal Mary deFlaun, Ph.D. (Princeton); Associate Gary Wealthall, Ph.D. (Guelph); Associate Bruce Marvin (Oakland), and Senior Consultant Andrew Cohen, Ph.D. (Princeton).
