Characterisation and monitoring of in-situ remediation of chlorinated hydrocarbon contamination using an interdisciplinary approach


MIRACHL is a R&D project aiming at improving methods and methodology for optimized planning and monitoring of in situ remediation of PCE – Perchloroethylene. PCE is a highly unhealthy contaminant often originating from dry cleaners. The aim is also to implement the technique in the industry.

In Sweden there is approximately 2000 PCE contaminated sites, waiting to be remediated. More efficient technique and methodology is needed to lower the very high costs for this.

This website will describe the MIRACHL project and the methods used, and continuously keep you updated of what is going on and what is achieved during the project 2017-2021.

MIRACHL is short for – Monitoring of In situ RemediAtion of CHLorinated hydrocarbon contaminants.


MIRACHL will combine geoelectrical imaging by the geophysical method Direct Current resistivity and Induced Polarisation (DCIP), Physical and BioGeochemical Characterisation (PBGC) and the method Compound-specific isotope analysis (CSIA). This means finding and monitoring the contaminant by measuring the electrical resistance of the soil in 3D and verifying the results with biogeochemical and isotope analyses of soil and water samples.


MIRACHL is a continuation of the former R&D projects MaLaGa and TRUST, carried out by the same team core. In MaLaGa – Mapping Landfill Gas using geophysics – we started to learn how to characterize gas and different waste and contaminants using geophysics. In TRUST – Transparent Underground Structures – we developed a deep understanding of the physical mechanisms on PCE contaminated sites affecting the signals during DCIP measurements, and also largely improved the 3D processing technique. In MIRACHL we will develop and finetune an applicable methodology and technique for the remediation industry.


Lund University is managing the project and hosts the majority of the researchers regarding geophysics and biogeochemistry.

Arhus University and Stockholm University supports with senior researchers in geophysical data processing and isotope technique.

Tyréns AB support with management and senior researchers in data analysing, communication and implementation in the industry.
