Ok so there's an industrial maintenance company down the road from me, they've got a decently sized fleet of tanker semis and late at night they take them out into a field and dump whatever chemicals they transport and then spread the shit into the ground with a couple dozers. I've never seen them doing it during the day but a few nights a week they'll be out there with no lights on dumping this waste, now its not very far from my house and it could be getting into the groundwater, should I report them and who should I report them too? Epa?
