Aplica？？o do método eletromagnético indutivo na investiga？？o da pluma de contamina？？o da água subterranea por resíduos de cromo de curtume

this paper presents the results obtained with the inductive electromagnetic method em-34, used to describe the contamination plume in aquifer due to wastes of tanning residues in várzea gra6nde, district, mato grosso state. this area was used for more than ten years as a place of disposal of sludge from tanning in ditches previously excavated in the soil. this area is currently seal off by the environmental govern. the results obtained with the application of electromagnetic inductive method showed that the level of 7.5 m and 15.0 m below the surface the soil conductivity on the ditch was approximately 2 to 3 times higher than the values measured on the road circulating the area of deposition. the highest values of apparent conductivity could also be related to higher concentrations of chromium in groundwater according to data obtained from chemical analysis conducted on water collected in wells tracking (sema). the tests in the area show the need to maintain a constant monitoring of the region due to the possibility of slow migration of contaminants to areas adjacent to the deposit.
