Arsenic contaminated soils, sediments and water supplies are the major source for the food chain. The main objective of this work is to analyze the arsenic and trace elements content in surface water and agricultural soils in the southeast of Córdoba province, Argentina. Arsenic concentrations in water samples from the Ctalamochita river were between <10 and 18 µg/L, bellow the allowed limit in the Córdoba province. In soils, total As, V and Sr concentration showed no significant differences between the levels found at different depths (30, 60 and 100 cm); values obtained ranged from 3.4 to 9.3 mg/kg, 50.6 to 65.5 mg/kg and 85 to 201 mg/kg, respectively. According to these results, As and V concentration in the studied soils was below the guidelines values considered in Argentina and within the range reported in non contaminated soils in various countries.
