Experimental Study on Chromium Contaminated Sites by Geophysical Methods

Looking into chromium contaminated site is helpful for maintenance and management of the environment. The susceptibility of tailings in industrial processes by combustion is several times than soil. The inorganic substance into the soil and groundwater makes magnetic and electrical difference. So preconditions and physical foundation is based on magnetic and electrical difference; In this paper, we have carried out looking into the chromium contaminated site in the Qinghai Haibei by high-precision magnetic survey(HPMS), high density resistivity(HDR) and induced polarization(IP). The results show that the abnormal body is a three-dimentional body, the volume of the body is calculated roughly based on the features of the abnormal curve and the inversion interpretation; electrical prospecting can investigate and monitor pollution in groundwater, because the concentration of harmful substances is greater than 100mg/L; clay adsorbs heavy metal ions, resulting in lower resistivity and higher rate of charge.
