Hydrogeologic Explorations to Benefit Farmers in the Atlas Mountains, Morocco
This January 31, 2024, webinar presents the methodologies and findings of hydrogeologic reconnaissance performed at 4 sites in the High Atlas Mountains and Middle Atlas Mountains in Morocco. Groundwater at each nursery has become scarce due to a persistent regional drought; wells have gone dry, springs are not providing enough water, and drilling new wells has not yielded water. This picture-rich presentation shows how integration of relatively basic observations and measurements, coupled with the use of commonly used and free software, can provide significant insight about hydrogeologic characteristics and provide the means to recommend actions to provide ample water to sustain growth of fruits at the nurseries. In addition, the webinar shows how the work and recommendations can be effectively communicated to stakeholders via an informal video recording.
Correction: the geologic outcrop shown/discussed at 14:15 is an outcrop of fractured cretaceous sedimentary rock, not volcanic rock.

Effect of Aquitards of Drinking Water Quality
Переглядів 21710 місяців тому
This simple animation illustrates how an aquitard (a low-permeability geologic layer such as clay or unfractured rock) hydraulically isolates a deep well, thereby protecting the water supply from shallow groundwater contamination. Conversely, in the absence of an aquitard, the sucking action of the deep well pulls the contaminant downward, thereby negatively impacting groundwater quality. This ...

USEPA Guidance on Groundwater Contaminated by PFAS is Flawed
Переглядів 169Рік тому
In this episode of EnviroGeoPro Talks, environmental consultant and Contaminant Hydrogeologist Andrew Cohen examines the U.S. EPA’s drinking water Health Advisory Levels (HALs) for PFAS compounds, particularly PFOA and PFOS. Recorded prior to the EPA's issuance of Maximum Contaminant Levels (MCLs), this presentation delves into the basis of these advisory levels and questions whether the scienc...

This 1 minute animation depicts remediation of groundwater contamination at a real site in Ohio. It shows how installation of extraction wells results in the capture of groundwater so that off-site groundwater flow is restricted. It also shows how the plume extent shrinks over time. The site operated from the 1950s through 2005. The property boundary is shown in yellow, and the former plant was...
