Environments we work in

Managed Aquifer Recharge

Managed aquifer recharge, where excess water is used to recharge the groundwater aquifers, has been proposed as a means of curbing groundwater depletion.

Fractured Hard Rock

In areas with fractured hard rock there is still a large potential for looking for groundwater. In regions with fractured hard rock formations our geoscanners excel.

Mapping Groundwater

In parts of the world with limited access to surface water, or where surface water is seasonal and/or contaminated, a groundwater solution could be to locate suitable aquifers.

Exploring Rivers

In river areas there is an increasing demand for characterizing the hydrogeology underlying rivers and estuaries. Knowledge about the interaction between river water and the groundwater is important.

Saltwater Intrusion

In coast-near areas, saltwater intrusion is a risk to freshwater aquifers. Our geoscanners are well suited for mapping saltwater boundaries both in areas prone to flooding or rising seawater, or affected by artificially lowered groundwater.

Well Siting Hard Rock

Well siting in hard rock areas involves the selection of an appropriate location for drilling a well in areas where the subsurface is primarily composed of hard rock formations.

Contamination

Locate contaminated areas and protect groundwater resources – its possible to map and assess subsurface contamination in soil and groundwater.

Raw Materials

When it comes to raw materials it is important to focus on the exploration and assessment of the earth’s subsurface for the purpose of locating and characterizing raw materials.

Weathered Bedrock

Understanding the properties and distribution of weathered bedrock is crucial for a wide range of applications, from construction and engineering to environmental assessments and resource exploration.

Permafrost Mapping

When accessing remote and challenging terrains, such as areas that remains at or below freezing temperatures (0°C or 32°F) for more than two consecutive years it is essential for understanding its distribution.
