Mining environment: preventing arsenic and lead contamination at Roure-les-Rosiers

02.04.2019
Environmental safety is in increasingly important part of post-mining management. A typical example is the work conducted on the lead and arsenic-rich residues from processing lead-silver ore at Roure-les-Rosiers.

New prospecting methods for deep geothermal resources

02.04.2019
From 2013 to 2017, under the EU Image project on high-temperature geothermal energy, the BRGM studied the very promising contexts of Europe's sedimentary basins and underlying bedrock, securing major advances in prospecting methodology.

Preventing flood risks during tsunamis or hurricanes

02.04.2019
From upstream modelling and research on the origins of tsunamis to crisis management during hurricanes, the BRGM is involved in all phases of flood risk prevention and monitoring. Examples in 2017.

Satellites and the Web to keep a close watch on underground storage

02.04.2019
Storing natural gas underground is one solution to keep supplies secure and absorb variations in demand and peaks in consumption, but this requires specific surveillance. The web-based geo-surveillance platform developed by the Web-RDS project is an innovative solution that combines observations...

Understanding the near subsurface to support sustainable and responsible development

02.04.2019
Because the near subsurface (0 to 100 m) is the interface between humans and the planet, it is the focus of a great many fundamental issues and the subject of many research projects.

Water security around the Mediterranean in the context of global change

02.04.2019
Water scarcities, overabstraction from water tables and shrinking resources combined with increasing demand from a growing population, agriculture and economic growth: this is the situation around the Mediterranean in the context of climate change that BRGM researchers are addressing in studies...

Airborne geophysics: assessing solid rock quarrying potential in La Réunion

11.29.2018
La Réunion is facing a shortage of solid rock supplies, which are essential to major civil engineering projects. To address the problem, the BRGM conducted a pilot study based on data collected in 2014 during the ReunEM heliborne geophysical survey campaign.

Heliborne geophysical survey of La Réunion: applications to materials prospecting

11.29.2018
Heliborne prospecting for materials can produce imagery of hard rock sectors on and below the surface, but can also identify the thickness of loose weathering formations (clays) that prevent access to these deposits and which can also be used in some cases.
