La presente invención provee un procedimiento para el tratamiento de sólidos o suelos que contienen Cr(VI) por medio de una reducción biológica insitu de Cr(VI) a Cr (III) insoluble. Los valores de pH de los sólidos que contiene Cr(VI) son ajustados con un ácido o una base a un pH deaproximadamente 6,5 a 9,5, siendo los mimos mezclados íntimamente con material orgánico (tal como estiércol) que contiene bacterias y nutrientes.The present invention provides a process for the treatment of Cr (VI) -containing solids or soils by means of an in situ biological reduction of Cr (VI) to insoluble Cr (III). The pH values of the solids containing Cr (VI) are adjusted with an acid or a base to a pH of approximately 6.5 to 9.5, the mimes being intimately mixed with organic material (such as manure) that contains bacteria and nutrients.
