I also thought of contamination if the back flow valve did not kick in in time. The softener does back wash under 50-60 pound pressure from the well tank. I've also been looking for a valve that would install near the softeners tank and drain off leftover water in the line after the the back flow valve and softeners backwash cycle ends. I was thinking in that way no contaminated, if any, water would touch the backwash water. I can't seem to locate that type of valve. I Googled unloader valve but that's for pressure washers.
I could run a line to my laundry sink upstairs about 40 ft away and let it drain into that. That would be an easy air gap. Problem there is family members soak clothes in there and that spells disaster if the softener starts to run.
I check around to see what others around here do and also check with septic and plumbers. I've heard the term air gap for dishwashers so I'll also see how they operate.
Thanks to everyone for the input.

My concern for you would be more that after a drain clog, it would contaminate the water softener/ potable water and KILL YOU (and others?)...
(Mike said) <<might want to check with a septic tank company-will the discharge from your water softener mess up your septic tank? is the discharge pressurized? if so, you may want to connect to the drain line thru an upward facing "Y" fitting so that the fall of the waste water will be forced down: that is, one side of the Y connects to the existing drain and your water softener drain would connect to the other side of the Y. when connecting a condensate drain (from and air conditioning coil for example) I am required to leave an air gap at my connection to avoid any back-up into my drain line;any back-up from the out going drain would spill out thru the air gap I suppose>>
