Subject: Is baking soda environmentally friendly?

I did a science fair project on household snow melters.  As a result it 
turned out that salt was the best snow melter.  However salt is not 
evvironmentally friendly.  In the spring when the snow melts the salt 
dissolves and starts drying up the plants in the soil.  I know I could find 
this out in a library or something, but i tried that and I found nothing.  
Even after searching your library.
I need this very soon.  In about two days or even sooner.  Sorry if I'm 
pushy, but I'm sitting on pins and needles to know the answer.  I need to 
know if baking soda has any effect like salt does on the environment, that 
would make it a "not environmentally friendle" substance.
Thank you
