7 System reliability as a function of distance from the source for selected monitoring systems for conventional monitoring approach: (a) homogenous medium, and (b) heterogeneous medium.

8 Average contaminated area as a function of distance from the source for selected monitoring systems for conventional monitoring approach: (a) homogenous medium and (b) heterogeneous medium.

9 System reliability as a function of distance from the source for a 3-well monitoring system for the proposed monitoring approach (pumping rate is 100 l/day).

10 Average contaminated area as a function of distance from the source for a 3-well monitoring system for the proposed monitoring approach (pumping rate is 100 l/day).

11 Influence of the pumping rate on (a) detection probability of a 3-well system

12 Influence of the pumping rate on (b) average contaminated area.

13 Comparison of the conventional and the proposed monitoring approaches (pumping rate = 100 l/day) in terms of reliability “in heterogeneous medium”: (a) transverse dispersivity,  T = 0.01 m, and (b) transverse dispersivity,  T = 0.03 m.

14 Comparison of the conventional and the proposed monitoring approaches (pumping rate = 100 l/day) in terms of the average contaminated area “in homogenous medium”: (a) transverse dispersivity,  T = 0.01 m and (b) transverse dispersivity,  T = 0.03 m.

16 Comparison of the conventional and the proposed monitoring approaches (pumping rate = 100 l/day) in terms of the average contaminated area “in heterogeneous medium”: (a) transverse dispersivity,  T = 0.01 m and (b) transverse dispersivity,  T = 0.03 m.

18 Expected cost as a function of number of wells in a monitoring system for transverse dispersivity,  T = 0.03 m: (a) homogenous medium and (b) heterogeneous medium.
