When dealing with restoration/remediation of contaminated aquifers, it is usual to determine the groundwater movement transporting the contaminant placing a line of wells downstream to the source of contamination to intercept the pollutant plume. This type of approach may imply extra costs compared to the case in which well locations are planned using a cost-based analysis. In this context, we have investigated a Bayesian-like methodology for locating sampling points and exploiting them as reactive wells. Wells are placed on the basis of a dynamic evaluation of the cost associated with the delivery of reacting oxygen promoting biodegradation of a dissolved contaminant. This work presents a preliminary modelling results regarding: 1) the ``optimal, localization of reactive wells relying basically on the methodology presented by James and Golerick (1994); 2) possible reduction of remediation costs due to the action of oxygen release from the selected wells (Gallo et al., 2004) in the contaminated soil; 3) cost analysis of the methodology. Furthermore, we discuss the assumptions made in this work for this preliminary evaluation and future developments of this study.
