Bot,
All that waste oil you pumped out went into the Schukyll and then the Deleware. I guess some could have come into the Chesapeake through the C&O, but I think the flow is into the delaware from the C&O. So I think your contribution to the Chesapeake is/was negligible.

But you are correct about the urban sprawl and the effects on the Susquhana drainage basin. Look at the area drained by that river and see what effect that has on the Chesapeake!
