Environmental Geochemical Research and Engineering Laboratory (LI2GA)

He Environmental Geochemical Engineering and Research Laboratory (LI2GA) addresses research related to environmental pollution processes from a geochemical approach. The lines of research are framed in:

• Geochemical and mathematical methods applied to the characterization of contamination processes in the soil and subsoil.
• Human health risk assessment.
• Ecosystem risk assessment.
• Urban pollution.
• Geochemical techniques for prospecting and investigation of subsoil contamination processes.
• Soil gas (Radon deficiency technique)
• Bioaccessibility and bioavailability of trace elements.
• Environmental mapping (GIS)

The Laboratory has developed intense research activity applied to various aspects related to the characterization of spaces contaminated by hydrocarbons and metals, complemented with the analysis of environmental risks. It was formed as a research laboratory in 2009, becoming part of the Network of Laboratories and Infrastructures of the Community of Madrid with reference number 263.

Among other works in this line, the Laboratory has developed the Generic Reference Levels for the protection of human health of heavy metals and other trace elements in soils of the Community of Madrid and the methodology developed for this has become a reference for similar projects. in other Autonomous Communities (Aragón, La Rioja, etc.).

The Laboratory is specialized in the development and application of techniques of screening for the detection of organic contaminants in the subsoil. In addition to classical soil-gas techniques, soil vapor detection (PID), chromatographic determinations of inert and light gases, and direct chemical analysis of borehole samples, the laboratory uses radiometric techniques, which have been proven effective, if present the appropriate geological conditions to locate and delineate the contour of subsurface accumulations of NAPLs, especially in the case of LNAPLs. The laboratory's experience in emanometric techniques dates back to the late 1990s and continues to the present day with the completion of doctoral theses and numerous research projects, both financed by private companies and public organizations.

In all works, special attention is paid to the mathematical and statistical aspects related to sampling design, quality control, spatial data analysis and modeling of surface and subsurface processes.
