The strategy of the MIRACHL project is to develop geophysical technique and methodology for monitoring in situ remediation of PCA contaminated sites in as close cooperation as possible in ongoing projects. Preliminary three main field sites are used – Kristianstad (Färgaren), Hagfors and Boden. Baseline measurements have already been carried out at the Kristianstad site and during the last week the geophysical baseline measurements started also at the Hagfors site. Tests were carried out with GPR, EM61, Dual EM and Magnetometer/Gradiometer.
A cut from the daily field report says: Nice and sunny! A bit of snowing during the night. Continuing measuring with the GPR. Today we did measurements at the surroundings of stream Örbäcken southwest of the secondary source. Measurements were done on the east side of the river, close to the small gravel road. The data was viewed in the field during sampling. From this quick overview we could see features and layers, however a proper software is needed for a more detailed analys. Coordinates for some start and endpoints of the sampling lines could not be determined with the GNSS due to bad receiving signal. The markers for these points were left in the ground. For next field trip, a total station will be used to aquire these coordinates.

This week also posters about the MIRACHL project are presented at the SAGEEP Conference in Denver, Colorado. The coming week the main annual event in the Sweden concerning contaminated soil , Renare Mark in Malmö,is taking place. On this conference two papers and one poster on the MIRACHL project are presented. The posters and the Conference papers will soon be uploaded on the MIRACHL website.
