Mr. David Livermore is a principal hydrogeologist and geochemist with 30 years of experience in solving complex earth science problems centered on the interaction of hydrogeologic, geologic, and atmospheric systems.  Mr. Livermore is a registered professional geologist in six states and a licensed hydrogeologist in Washington.  Mr. Livermore has successfully managed the investigation and cleanup of hazardous waste sites throughout the United States and specializes in developing innovative strategies and solutions for negotiating streamlined site closures with regulatory agencies. Mr. Livermore’s expertise includes the hydrogeologic and geochemical assessment and cleanup of soil, sediment, and groundwater contamination at complex hazardous waste sites.  Mr. Livermore’s hydrogeologic expertise includes regional hydrogeologic studies, the evaluation of tidal- or river-stage-influenced aquifers near-surface water bodies, groundwater/surface water interactions, and the resulting implications for contaminant fate and transport.  Mr. Livermore’s geochemical experience includes vadose zone transport of chemicals, geochemical processes affecting chemical natural attenuation, and the effects of cosolvency on the mobility of chemicals in the environment.  For site remediation, Mr. Livermore’s expertise includes the analysis and optimization of remediation systems, nonaqueous-phase liquid (NAPL) remediation at sites with complex stratigraphy, and the strategic assessment and costing of alternative remedial options. For environmental litigation, Mr. Livermore has developed expert testimony and provided courtroom testimony on the source, extent, and timing of contaminant releases.  His hydrogeochemical conceptual site models (CSMs) have proven instrumental in the mediation and/or settlement of legal suits involving the source and timing of chemical releases to the environment.  Mr. Livermore has also used CSMs and fate and transport analyses to develop models for allocating remedial costs from multiple contaminant sources.
