Hydrogeologic Exploration to Benefit Farmers in Morocco

Communication and Education, Fractured Rock Hydrogeology, Non-Profit, Site Assessment and Characterization, Visualization /

Hydrogeologic reconnaissance was performed at 4 sites in the High Atlas Mountains and Middle Atlas Mountains in Morocco with the purpose of identifying locations for accessing groundwater for irrigation. The work was performed in collaboration with the High Atlas Foundation.     This January 31, 2024, webinar presents the methodologies and findings of hydrogeologic reconnaissance

Estimated Allocation Share for Contaminated Sediment

Expert Witness and Legal Support, Fate and Transport, Sediment and Surface Water, Wastewater /

Why This Engagement Mattered Determination of allocation share for contaminated river sediment required assessment of whether a former manufacturing facility contributed contaminants of concern at levels relevant to financial responsibility. The technical dispute focused on estimation of contaminant mass flux associated with permitted sewer discharges and the accuracy of calculations used within the allocation framework.

Forensic Evaluation of PFAS Contamination at Air National Guard Base

Chlorinated Solvents and DNAPL, Forensic Hydrogeology, PFAS, Site Assessment and Characterization /

Evaluated groundwater data, including chemical signatures based on 21 PFAS compounds across shallow, intermediate, and deep aquifer zones. The analysis integrated groundwater flow directions, potential source locations, and chemical compositions from both on-site and off-site sources. Key conclusions highlighted the identification of off-site PFAS sources north of the site and attributed PFAS detections in the

Technical Lead – DNAPL Megasite

Chlorinated Solvents and DNAPL, Fate and Transport, Forensic Hydrogeology, Modeling, Site Assessment and Characterization, Unique Analytical Methods, Wastewater /

Served as the Technical Lead for numerous and large site investigation and remediation projects at a 1,400+acre chemical manufacturing plant, which included extensive soil and groundwater contamination by dense non-aqueous phase liquid (DNAPL). Multiple projects, including investigation planning and analysis of site-wide data to identify sources, nature and extent, fate and transport, and risks associated

Identification of Responsible Party: Contaminated Groundwater

Chlorinated Solvents and DNAPL, Expert Witness and Legal Support, Fate and Transport, Forensic Hydrogeology, Site Assessment and Characterization /

Independent forensic hydrogeologic evaluation of chlorinated solvent contamination using chemical, hydrogeologic, and historical data analyses to assess potential responsible party status. Why This Engagement Mattered   Responsibility for PCE- and TCE-related soil and groundwater contamination depended on whether releases pre- or post-dated specific ownership and operational periods. The technical dispute centered on contaminant age, plume

“Occurrence and Migration of PFAS Firefighting Foam in Surface Water and Groundwater”

Communication and Education, Fate and Transport, PFAS, Visualization /

This webinar presents some of the fundamentals of groundwater and surface water contamination due to firefighting foams that are composed of Aqueous Film Forming Foam (AFFF), which contain Per- and polyfluoroalkyl substances (PFAS). PFAS are a group of man-made chemicals that include PFOA and PFOS, and which have been referred to as “Forever Chemicals” because

Animation of Pump and Treat Remediation

Communication and Education, Expert Witness and Legal Support, Fate and Transport, Visualization /

This animation was created using a custom animation technique – offering teams a clear, cost-effective alternative to traditional groundwater modeling software. It can be designed to support litigation, including courtroom presentations and expert testimony, while also serving corporate remediation leads, environmental consultants, and regulators who need to communicate site conditions to the public and other

Simulation of DNAPL Contamination in a Fractured Rock Aquifer

Chlorinated Solvents and DNAPL, Communication and Education, Expert Witness and Legal Support, Fractured Rock Hydrogeology, Visualization /

This simulation illustrates some fundamentals of dense non-aqueous phase liquid (DNAPL) transport in fractured rock.   A unique aspect of this video is that the simulation is created using a custom animation technique without the use of complex groundwater modeling software. This cost-effective method provides a clear, intuitive way to communicate site conditions to stakeholders, making it an

“Groundwater Pollution for Beginners”

Chlorinated Solvents and DNAPL, Communication and Education, Fate and Transport, Visualization /

This educational video is aimed at those unfamiliar with groundwater resources and groundwater contamination. The exclusion of audio is purposeful; the video guides the “reader” during the groundwater contamination simulation and visualization of groundwater plumes. This “animated reading” approach enables self-paced learning, including further contemplation when needed by pausing the video without losing the value
