Dr. Steve Brauner is a registered professional engineer with a demonstrated history of excellence in project management, site investigation, and the identification and implementation of effective solutions to a wide range of environmental challenges. During 15+ years of professional practice, Dr. Brauner has specialized in design and implementation of cost-effective, technically-sound approaches for remediation of contaminated soil and groundwater. His designs consider and incorporate green remediation practices that reduce cost, carbon footprint, and greenhouse gas emissions using a combination of beneficial reuse, waste minimization, conversion of remedial systems from active to passive systems, and use of renewable energy sources.
Dr. Brauner has managed multidisciplinary technical teams at multiple sites across the globe, and has led regulatory negotiations under CERCLA, RCRA, and multiple state regulatory frameworks to achieve complete or partial shutdown of remediation systems that were no longer effective. Remedial designs that have been implemented by Dr. Brauner significantly improved the performance of existing remedies by optimizing system operations and/or directly reducing contaminant mass in source areas. Dr. Brauner has used his extensive experience with conceptual site model development and dynamic work plans to identify critical data gaps and expedite the collection of supplemental data necessary to ensure that implemented remedies were optimized for performance and cost. The end result of these efforts has been a consistent reduction in life cycle costs and environmental liability for his clients. His experience also includes litigation support and evaluation/testing of water supply projects in Colorado, Bolivia, and Honduras.
Dr. Brauner’s technical acumen is supported and complemented by excellent communication, organization, leadership, and collaboration skills. His extensive practical knowledge and consulting experience enable him to deliver solutions that are scientifically rigorous, technically feasible, cost-effective, timely, and consistent with all applicable state and federal regulations. Looking ahead, Dr. Brauner remains eager to collaborate with and support existing and new clients in reducing the cost, carbon footprint, timeframe, and overall liability for achieving a remediation endpoint for contaminated sites, both large and small.
Originally from the Connecticut River Valley of Western Massachusetts, Brian entered the U.S. Navy out of high school and became an antisubmarine warfare operator tracking submarines aboard a P-3 Orion. After 4 years of service, Brian went to college and received his Bachelor of Science degree in Geology, Chemistry, and a minor in mathematics at Bridgewater State University (Magna Cum Laude) and his Master of Science in Chemical Oceanography at the University of Washington. Brian’s Master’s thesis incorporated the formation of thorium-carbonate complexes in the laboratory with MINEQL, a chemical equilibrium model. While working as an oceanographer at UW, Brian studied water-rock interactions and videoed ‘black smokers’ off the Juan de Fuca Ridge. He experienced the bottom of the ocean in ALVIN, the submarine from the Woods Hole Oceanographic Institution. Brian joined Harding Lawson Associates in 1988 and left in 1999 to pursue the life of an independent consultant and the culinary world before joining Nationwide Environmental Services (NES) in 2006. After 13 years with NES, Brian is currently seeking a new challenge.
Brian has evaluated geochemical data to assess the natural background concentration of metals for active mine sites; interpreted radioisotope data to delineate multiple aquifers at complex sites; conducted numerous fate and transport modeling efforts; and managed multi-million dollar Superfund CERCLA projects through the RI/FS and RD/RA processes. Brian has managed long-term remediation operation and maintenance actions at Superfund sites, and provides technical and regulatory strategies to clients to minimize their exposure to environmental liabilities. Outside the rigors of the consulting world, Brian enjoys cross-country skiing and hiking with his wife and dog; golfing with his friends, colleagues, and clients; and sharing culinary creations.

Noreen retired from federal employment in April 2018. As a former regulatory permit writer at CDPHE, DOE and EPA, my favorite activity was the informal give-and-take fostered between government regulators, consultants, engineers, scientists, policy makers, attorneys, and academics at CEMS. I now agree with my first grade teacher, Dorothy Darling Peck, the ability to get along with and work with other people is the most important skill in life. If you have fun, all the better.
