SITEREM uses the latest technology to identify and distinguish land and groundwater pollution.
It boasts effective, reliable tools for measuring and investigating, including drilling machines, multi-parameter probes, GPS, pumps for extracting water or pumping tests. SITEREM also uses modelling tools to understand and predict the movement of groundwater and pollution in the earth.
SITEREM works closely with external organisations who use special recognition techniques (mechanical excavation, seismic and electrical resistivity tomography, MIPs etc.) and analysis methods (laboratory, university etc.).
SITEREM carries out comprehensive diagnoses:
- historical survey of activities/infrastructures
- topographic, pedological, geological and hydrogeological measurements
- managing and following up field sampling
- analysis and interpretation of the data collected
- assessment of risks to human health, water resources and ecosystems
- putting together a compliance record for internal use or for the authorities
SITEREM gives clients the most appropriate recommendations from an administrative, technical and financial point of view.
Field investigations are usually carried out with manual or mechanical excavations. Mechanical excavations use a hydraulic hammer, hitting or rotating a boring tool.
As it is being extracted, the soil or rock is inspected (colour, appearance, smell, texture, dampness etc.) and samples are taken from the most suspicious areas or the most likely to be polluted.
If an area of groundwater is encountered during this process, a sampling well (piezometer) is set up to identify the quality of the groundwater.
Samples or earth or water are sent to an accredited laboratory in the Walloon Region or the Brussels-Capital Region to analyse hazardous or toxic waste.
