Pollutants can be added, deleted, renamed or merged together.  Pollutant names must be unique and are case sensitive, if duplicate names are entered these are modified to be unique.

If  Stormwater Controls - SWC or Inflows are created or loaded from another source, any pollutants that are not available are added automatically. 

Note: pollutant names are case sensitive so some duplication may occur, use the Merge functionality to eliminate duplicates.

The number of pollutants is limited to fifteen.


Add - Adds a new Pollutant to the end of the list.

Delete - Deletes currently selected Pollutant.

Merge - Only the lead pollutant remains and all other selected pollutants are deleted.  


When merging the pollutant concentration (Inflow) or removal values (Stormwater Control) from the first pollutant will be kept. However if value is 0 the next set of values will be used.
