Look up the Environmental Protection Agency (EPA) for your area and call them. I had a problem with people burning trash and they were the only ones who did something about it. Take pictures and keep records of what and when you had the waste on your property.
I thought my chickens would go nuts if I bought some nightcrawlers and fed them to them; but believe it or not they just looked at them and walked away and within a few seconds they disappeared underground. Lost money on that one! They do love popped popcorn though!
