Army airfield pumping something in the air?

So I was playing with the AQI filter on google maps. I found this suspicious looking puddle, and look what the source of the bad AQI is 👀👀 a military airfield. Not saying 100% it is the source, but looks very suspiciously like the source. It looks a glass of water dropped on a table. I’m not saying 100% the military airfield was the glass, but certainly looks like the glass 👀

What is in this area? It can’t be their planes
