In this chapter, we will use zone analysis to determine the effect of gas
tank leakage. The first analysis is similar to the one we did before,
except that we will involve all gas stations this time. This is equivalent
to finding affected parcels if the gasoline tanks in all gas stations leak
at the same time. In the second analysis, we will find the parcels
affected by a leakage from any of them. We will also change the model and
assume that a leakage will affect an area of 200 metres around the
contamination source.
The first analysis involves the following steps.
The second analysis involves the following steps.
