A wheelbarrow full of trash…

in broad day light saw a man with a wheelbarrow full of trash bags just dump it at a spot pretty close to where I'm currently living. Took a few trips and disappeared to somewhere, didn't see where exactly this person went to. Obviously this needs to reported but not sure how to do it and the person doing the dumping should get a punishment of some sort just so it isn't done again. I drove around the neighborhood and noticed a few more places where this is happening. Anyone have any suggestions on what to do?

Am I tripping or is this a common thing? Don't want to branded as a crazy person but this is just wrong. open to ideas
