When I say add antifreeze, I'm only talking like 1/2 cup. Diluted with the water already in there, which is no more than 1/2 cup, I thought it would be ok
Suppose 1% of the inground sprinkler owners in your state thought the same way. How much antifreeze would wind up in storm sewers and ultimately in rivers, streams, ponds, lakes, etc.?
Again, going back to the other poster, this is the non-toxic stuff.

I'm sorry, but I am not familiar with all of the components and processes that go into the manufacturing of antifreeze. I did not know that there was a type that is environmentally friendly. I understand your pain though. I would hate to have to pay the landscaping company to come back again and blow out the lines around my place.
Well IF he put antifreeze in there it surely would be the pink rv stuff that is totally harmless. AND even IF it were the automotive stuff, 15 million cups of the stuff diluted the way we're talking about would be harmless also.

I just had an idea. Since this is only a 3/4" PVC about 30 feet long with the other end open under my deck, I think I can get away with using a nail gun compressor. It 6 gal. It should be enough volume to push out whatever is in there.
I ran propylene glycol into my rather extensive system of drippers. If it does damage I'll have a dead blueberry field. Let's hope that next spring I don't have a disaster. In prior years I haven't noticed any damage to the weeds growing under my boats from propylene glycol.

Hey John, wondering where you think the billions of litres/gallons of winds hield wiper antifreeze from all of the cars ends up? I know that mine just runs onto the ground. Apparently nobody thinks this is a problem so I can 't see why it would be an issue to put it in your underground sprinkler pip es. Just sayin. I am talking about non-toxic RV antifreeze.
The windshield wiper fluid antifreeze usually contains methyl alcohol although some Prestone products have a percent or two of ethylene glycol.
It's down in section 12:
"Methyl alcohol is expected to biodegrade in soil and water very rapidly."
That one isn't as clear cut but does say 'Persistence is unlikely'. Other MSDS documents are also unclear. The big problem is animals drinking high concentrations.
