Applications for Conceptual Site Models from Aestus
The Aestus GeoTrax CSM+™ process develops conceptual site models for a variety of applications, including:
- Delineating the vertical and horizontal extent of light non-aqueous phase liquids (LNAPL), dense non-aqueous phase liquids (DNAPL), and aqueous phase impacts
- Locating the source of impacts to surface water bodies, such as seeps and sheens
- Identifying the source and extent of brine spills at oil and gas industry production sites
- Delineating waste prism and leachate issues associated with landfills
- Better understanding hydrogeology and preferential pathways, including karst
- Evaluating bioactivity, including delineating zones of natural or enhanced bioactivity
- Delineating environmental impacts in sub-aqueous sediments
- Monitoring substrate injection: where should one inject and where did it go
Other industry applications for conceptual site models from Aestus include, but are not limited to:
- Siting production water wells, avoiding the costly drilling-blind scenario by scanning first
- Detecting karst, voids, and caves related to engineering concerns regarding sinkholes and settlement
- Mapping subsurface geotechnical properties and issues
- Mapping and imaging subsurface archaeological features
- Mining operations, such as for locating gold-bearing gravel zones
Applications for 3D and 4D transient subsurface monitoring* available from the Aestus GeoTrax CSM+™ process include, but are not limited to:
- Monitoring injection sites
- Determining contaminant excursions beyond a point of compliance or property boundary
- Mapping subsurface geotechnical properties and issues
- Locating tunnels related to homeland security concerns
- Detecting saline intrusion into drinking water wells
- Check for piping in earthen dams
*3-D and 4-D (i.e., 3-D over Time) transient subsurface monitoring is achieved by installing dedicated electrode cable(s) in the subsurface and monitoring the same set of electrode cables at a set time interval to look for changes in the subsurface that may indicate a problem that needs to be addressed.
