# Using sodium chloride load as a point source pollutant variable in SWAT model?

I'm currently working with the Soil & Water Assessment Tool (SWAT). My task is to model the loading of sodium chloride into streams.

One approach I would like to take is to use the point source rechour.dat file command. The file can contain several variables regarding pollutant load.
For example:

• ORGPHR is the organic P loading kg/hr,
• NO3HR is NO3 loading kg/hr,
• DISOXHR is O2 loading kg/hr,
• etc...

Am I able to customize a new variable explicitly NaCl, or will I have to use CMTl1HR which is a heavy metal loading kg/hr?
