The first step is to identify which contaminant cascades for each sink
should be assigned. The purpose of this step is also to determine the
most likely source prioritisation sequence for each sink. This is
performed by determining the ratio of shifted sink concentration to the
shifted maximum of source concentration
(Z*k,sk/C*k,sr_max) for each
contaminant ’k’. Table 3 presents the results, and it shows that SK1 and
SK3 should be in contaminant cascade ’A’, while SK2 and SK4 should be in
contaminant ’B’ cascade, based on the smallest value of the ratio.
