the bay area has three major international airports and a very high amount of air traffic. I expect to see contrails, and as for barium contamination.i can understand you rlogic homeslice, but the point you are missing in your contamination theory is , it is across scale, these chemicals are not just found in the water or ground, but a spike has been registered in all places, of those well known and loved heavy metals, so computers are drenched in barium?
it is sad you can not see what is happening well or you won't let yourself see, humble yourself to the world, see the dangers in front of it, not some naive pollution but a real intent on changing the planet,
you do not disperse salts into the atmosphere if you are not looking for change,
look up with open eyes, and see why contrails form a haze you live and work in he bay area, so you know you see it,
I doubt they would fire you for speaking truth, they aren't truly the government, only they do things like that, hahah
barium, cadmium, beryllium, chromium, lead, mercury, germanium, copper, tin, aluminum, etc are all found in electronic waste and semi-conductor manufacturer. And what does the bay area have the most of? Silicone Valley manufacturing and large amounts of consumers buying electronic goods. Hell there's about 500 pages worth of EPA papers about the leaching of ewaste into ground water and soil contamination. Even third world countries are suffering this because we send them our e-waste, and a lot of e-waste is burned or destroyed in acid to recycle the precious gold and copper but as a byproduct releases toxic chemicals which float in the air and get deposited up to a couple of hundred miles away if it catches a good wind.
now thats ground level pollution, dropping chemicals at 30,000 feet over the bay area would disperse and dilute whatever"spray" they use for much more then 500 miles. It's worthless at that height.
Hell even a ground level 10 kiloton nuke would only create air carried fall out for a 100 or so miles.
