This project is part of the research area:
Measurement techniques and site investigation
Abstract:The project is part of a group of projects called “High-Tech Methods for in-situ Sounding”. In Germany about 100 ha of land is used for housing and traffic per day, one half of which is sealed. The area used for these purposes has doubled in the past 50 years. At the same time, the number of brownfields inside the cities is steadily growing.
An approach to reduce this consumption of land is the forceful reuse of
industrial, commercial and military brownfields, especially the areas inside of
cities. Many of these sites, however, are potentially contaminated. The use of
on-site analytical methods could substantially improve the process of assessing
the potential hazards. For this reason, the DBU (Deutsche Bundesstiftung Umwelt, Federal German Foundation Environment) funded a research network “High-Tech Methods for Subsurface Assessment”. Aim of this network was to combine handheld sounding methods with costly and modern sensor systems. By that, it should be possible to produce analytical information during the sounding. The network consisted of 14 research projects with their own organizational structure and aims.
In this project, different sensor systems were used to detect groups of
contaminants (e.g. HHC, BTXE) in soil air, NAPL phases, or dissolved
contaminants in the ground water. By using cost effective and simple sensors,
which are commercially available, measurement systems should be realized, which
are simple to operate and provide the possibility to react on findings directly
in the field, e.g. by optimizing the measuring grid. The sensors were designed
to give signals selective for groups of contaminants or just yes/no signals that indicate the presence of NAPL phases.
The prototypes developed during the project could be successfully demonstrated
and it could be shown that miniaturized sensor systems can be combined to
sounding systems and give valuable information in real time about the presence
of contaminants in the field.
