What should we do if the contractor uses large amounts of fertilizers and feed to raise fish in the village reservoir, damaging the ecological environment?

The contractor put a lot of fertilizers and feed in the village reservoir to raise fish, which damaged the ecological environment. We can report this to the village committee and the local government, or we can report it to their environmental protection department. If they don't care, they will secretly give the fish some drugs.
