Abstract The objective of this study was to estimate the theoretical investment needed for the remediation of river water in the upper and middle course of the Lujan River (Buenos Aires province, Argentina). Two source of data were used: a) a monthly water sampling in the river over a 27 month period, and b) the Environmental Record of the Municipality of Lujan, where the estimated effluent discharges of the industries and the city of Lujan are registered. The number of days needed to produce the depuration of river water was estimated relating the biological oxygen demand (BOD) and the chemical oxygen demand (COD) with the dissolved oxygen concentration in water. In addition to this, and assuming that all the effluents that flow into the river do not exceed the DBO standa
