|Abstract||Subsurface water pollution due to landfill leaks has become an important issue the last three decades. Subsurface heterogeneity and lack of information about the exact location and duration of a leak render it extremely difficult to predict and detect subsurface water pollution before it has already spread and become evident. The subject of this study is the calculation of the detection probability of an instantaneous leak originating from a random location inside the boundaries of a two-dimensional rectangular landfill that can be achieved by a linear arrangement of monitoring wells. Calculations take place in a Monte Carlo stochastic framework, with the subsurface heterogeneity reproduced by the Turning Bands method and the flow of the pollutant plume described by the Random Walk Particle Tracking method. The resulting computational model provides the detection probability and area of a subsurface pollutant plume for a linear configuration of monitoring wells. An empirical formula was also derived that can be used to calculate in a simple manner the detection probability of contaminants for different configuration of wells.|
