The Geosyntec family of companies is pleased to announce the promotion of Arthur Forma, Darrell Nicholas, Dave Adilman, Derek Tomlinson, Eric Sager, Eric Suchomel, Helen Dawson, Jeff Ahrens, Kyle LaClair, Marc Leisenring, Mark Johnson, Mike Lambert, Ming Zhu, Rebecca Daprato, and Steve Foster to the position of Principal within the Geosyntec family of companies. Each of these people have made significant contributions to delivering outstanding projects to first-class clients, developing strong relationships with those clients, building our practices, leveraging their own experience and that of their colleagues, recruiting outstanding staff, and working collaboratively with their co-workers.

Arthur Forma, P.G., CEG, CHG (California)

Arthur's practice includes geologic, hydrogeologic, geotechnical, hazardous waste investigation and remediation, and environmental due diligence. His groundwater investigations, conceptual site models, and remedial action programs have helped clients achieve­ regulatory compliance for sites contaminated with petroleum hydrocarbons, chlorinated solvents, polycyclic aromatic hydrocarbons, metals, pesticides, and perchlorate, even when those sites involve complex hydrostratigraphic terrains. His work in due diligence includes Phase I and Phase II Environmental Site Assessments for real estate transactions at industrial, commercial, agricultural, and residential sites. He helps drive the use of the Electronic Field Data Collection and Reporting "GroundLoggr" tablet app. This app can provide cost savings to clients by reducing manual data entry and by tracking scope automatically. Arthur earned his B.S. in Geosciences from California State University in 2000.

Darrell Nicholas, P.E. (Tennessee)

Darrell's practice is focused on the remediation of contaminated sediments with an emphasis on remedial design and remedial action at large sites. He is one of the world's foremost dredging, sediment handling, and dewatering experts, having led the design and management of some of the largest and most complex sediment remediation projects in the world over the past two decades. Applying his problem-solving skills and knowledge of mechanical and hydraulic dredging technology, he has supported clients in the remediation of more than two million cubic yards of contaminated sediments while earning national and international innovation awards. Annually, he is an instructor for the Texas A&M Dredging Short Course, a nationally recognized course for training engineers in sediment management. Darrell earned his B.S. in Civil and Environmental Engineering from Tennessee Technological University in 1978, and his M.S. in Civil Engineering from the University of Kentucky in 1979.
