Time Domain Reflectometry (TDR) - Measuring Dielectric Constant of Polluted Soil to Estimate Diesel Oil Content

The paper presents results of experimental study on the possibility of calculating the content of diesel oil in soils from measurements of dielectric permittivity with the TDR technique in a soil-water-air-diesel oil system. Results of calculation were compared with the actual content of diesel oil measured in laboratory conditions. The comparison shows that the content of diesel oil in soils may be precisely determined pn the basid of measurements of dielectric permittivity in contaminated soils.
