This is difficult to answer because it requires knowledge of the thoughts of the officials. That’s impossible to know. If an official actually knows that the “Waters of the Commonwealth” are the responsibility of the state then it’s impossible to understand why that official would say the local government cannot do anything about the poison found in some of the West End wells.
On the other hand, if an official knows the township has some responsibility to help figure out what should be done about the poisoned wells and refuses to get involved then the idea of negligence has some basis.
The response of officials who knew the township had responsibility probably should have been to at least study the situation and try to figure out what should have been done. But there is no way to figure out whether the official is lying or didn’t know.
