Point source pollution is when you can tell where the pollution came from (like hog waste in the water supply).
Non-point source pollution is when you can't really tell where the pollution came from (like excess
Because it is harder to determine where non-point source pollution comes from, it is harder to take actions to stop this problem. This is one of the reasons why it is worse.
