Walnut Creek, CA (May 16, 2012) – Murray Einarson and Peter Bennett join Haley & Aldrich as a Technical Experts/Client leaders in the San Francisco Bay Area to continue the growth of our operations and expand our hydrogeological, remediation, and litigation support practices nationwide.

Murray Einarson
At Haley & Aldrich, Mr. Einarson will assist manufacturing, aerospace, energy, and natural resource clients in providing solutions to complicated hydrogeological and environmental challenges. Mr. Einarson has 30 years of experience in the development, testing, and application of innovative approaches and technologies for cost-effective environmental site characterization and in-situ remediation. His expertise includes defining and evaluating processes that control non-aqueous phase liquid (NAPL) source zone dissolution and the subsequent creation and migration of dissolved plumes of contaminants and reaction byproducts. Mr. Einarson has expertise in small-scale contaminant hydrogeology but particularly enjoys projects that require holistic evaluations of potential impacts to water supply wells resulting from releases of contaminants to groundwater aquifers. He is a pioneer in the development and application of expedited site assessment technologies and has co-authored industry and regulatory guidance documents on this subject. He also holds patents on innovative site assessment technologies, including a dual-tube soil coring system and a multi-level groundwater monitoring system (CMT™ multilevel monitoring system).

Mr. Einarson is a frequent lecturer to environmental regulators in California and other states. He has authored or co-authored dozens of technical publications and regularly serves as a peer reviewer for several technical journals. He has been an instructor in the Princeton Remediation course and the University of Waterloo graduate course in field hydrogeology for the last 10 years. In addition, Mr. Einarson is a Consulting Assistant Professor in the Department of Civil and Environmental Engineering at Stanford University.

In honor of his many accomplishments in the field of contaminant hydrogeology and groundwater protection, the National Ground Water Association awarded Mr. Einarson its Ground Water Technology Award in 2009.

Peter Bennett
Mr. Bennett has more than 14 years of experience with innovative site characterization and remediation projects. He has served as the project manager and technical lead for several Superfund sites in California and routinely assists his clients with the management of these sites to reduce the cost and liability associated with old chemical releases. Much of Bennett's practical experience includes work at sites with commingled (multisource) plumes, vapor intrusion concerns, and property development. He has implemented low-cost in situ remediation programs at several sites as alternatives to groundwater extraction.

Throughout his career, Mr. Bennett has played a major role in designing, testing, and implementing new approaches for cost-effective groundwater remediation. This includes the first field program evaluating the diffusive release of hydrogen gas for in situ bioremediation of chlorinated solvents; the first on-site preparation and use of starch-stabilized nano-particles composed of palladium and iron (for chlorinated hydrocarbon remediation); the first bioGAC system for ex situ treatment of vinyl chloride; and a unique multiple funnel-and-gate system, where 172 treatment gates composed of iron filings were installed between low-permeability slurry panels to form a subsurface treatment wall 371 feet long and 60 feet deep. Recent work has also included using stable isotope assessments for evaluating the biodegradation of MTBE (methyl tert-butyl ether) and TCE (trichloroethylene) at field sites, designing and implementing single well tests for measuring groundwater velocity, and evaluating remedial options for chlorinated solvent source zones and dissolved plumes. Mr. Bennett is a member of the Science Advisory Board for a multi-million dollar, multi-disciplinary research program funded by the Canadian government which involves studying the synergies associated with combined in situ treatment technologies.

Much of Mr. Bennett’s practical experience includes work at sites with commingled (multisource) plumes, vapor intrusion concerns, and property development. He has also completed several projects at closed and operating Class I/II and III landfill sites, including landfill gas assessments, monitoring well installations, and responses to groundwater detections in accordance with Title 27.
