Upon completion of the contaminant source inventory, a representative of the water system and a representative of the Department shall jointly perform a susceptibility analysis of all contaminant sources identified in the contaminant source inventory.

1. (a) Contaminant sources shall be analyzed for their susceptibility to impact raw water quality. Contaminant sources shall be classed as highly susceptible, moderately susceptible, or not susceptible to impacting raw water quality after consideration of, but not limited to, the following factors:

   1. 1. Contaminant source nature, location, type, and source.
   2. 2. Concentration and volume of contaminant source after consideration of time of travel to the intake, and dilution.
   3. 3. Likelihood the contaminant source can be removed or diverted from the intake by emergency operations measures.

2. (b) All contaminants shall be plotted on the watershed map by using latitudes and longitudes based on GPS methods. The contaminants sources shall be identified by name and by legend on the map, using color codes to identify their susceptibility classification. The susceptibility codes to be used are:

   1. 1. Red: Highly susceptible
   2. 2. Yellow: Moderately susceptible
   3. 3. Green: Low susceptible.
