This study is the second phase of an institutional cooperation project between Universidad Pontificia Bolivariana,in Bucaramanga and the Colombian Institute of Petroleum,in order to provide a solution to a problem presented in sandysoils contaminated with diesel up to concentrations of 6% anda maximum depth of 80 cm. Artificially soil was contaminatedwith diesel at 2%, 4% and 6% by weight and evaluated usingthe Bioventing technique in soil columns. Monitoring parameterswere: inflow, diesel concentration, dissolved oxygen and bacterialgrowth, these parameters were monitored for four months. Theresults showed that the Bioventing technique is effective in sandysoils with low organic matter content, low infiltration flow, pHbetween 6-8, operating temperature of 22 ° C and dissolve doxygen concentrations above 0.5 mg/L. With these conditions,diesel removal percentages above 50% in diesel contaminated soil with an initial concentration of 2% by weight was found.
