No, the Hooker case doesn’t have to do with dumping chemicals into the river and spreading that way. But in such cases, states can and do sue offending states and get it heard in court for such. I believe Belgium or Netherlands sued France for contaminating the water underground or such.
Economics often play a role, when a state is economically backwards, environmental issues take a backseat, which may happen much in New York or New Jersey, despite their much-touted Democrat concern for the environment. Which is another good argument for state supervision, you live in the bed you make for yourself.
The real moral is that if you care deeply about the environment, then you should care about economics more, that is, good economics. When more capital is available in a country (or state), more people are free to divert their energies and finances into secondary hobbies, interests, and improving the environment becomes much more important than when funds are lacking.
