Tamzen Macbeth is an internationally recognized remediation expert specializing in the development, demonstration and implementation of innovative, cost-effective technologies for contaminated soil, sediment and groundwater. She has worked on over 100 government, private and international contaminated sites at the laboratory-scale, pilot-scale and full-scale levels. With experience bridging scientific and engineering R&D with the design and optimization of cost-effective cleanup programs, Tamzen has helped advance countless technologies within her field. In addition to her work at CDM Smith, Tamzen has published more than 100 technical papers, training manuals and guidance documents on remediation topics, as well as presented at seminars and international conferences to advance remediation technologies. She was also recognized with CDM Smith's President's Award for Innovation in 2016.
Why are you a part of CDM Smith? CDM Smith lives and breathes our core value of technical excellence, and our matrix organization allows us to put the best and brightest people on every project no matter where they “reside” across the world. We have deep technical knowledge across the firm, and we focus on knowledge sharing and mentoring to ensure that we are bringing up the next generation of technical experts.
What’s a project or accomplishment that you’re particularly proud of, and why? We are nearly finished building a pilot plant for a PFAS-destruction treatment train using foam fractionation to concentrate PFAS from dilute water streams, electrochemical oxidation to destroy PFAS and a perchlorate polish to provide a complete solution for water treatment. Our approach has the potential to leverage synergistic technologies to provide a more sustainable solution for PFAS treatment.
I hold everything we do to the highest standard and strive to go the extra mile to exceed expectations.
Tamzen is a member of several professional organizations, including the American Society for Microbiology and the Society of Women Engineers.
