The soil conductivity test is conducted with a specialised module attached to a CPT(u) cone allowing simultaneous acquisition of CPT(u) data and SMP data. The SMP enables in-situ measurements of the soil moisture content and electrical conductivity and can also be used as a screening tool for various pollutants. The SMP directly measures the electrical conductivity (Ec) up to 200 mS/m and the permittivity (Ɛ) between 1 and 100. The output enables tracking of saltwater carrying layers and detection of contamination. Examples: – quantification of salt water intrusion into fresh water aquifers – identification of contaminated groundwater or soil – determination of soil layers by deviations from the typical electrical conductance of water Useful information on the SMP can be found on the following link – geotechnical-cones/electric-conductivity-cone
