There are roughly 7.1 million nodes in Massachussetts, and 270k of them share the same location as another node. This is just an analysis based on location, not on tags, but it can be assumed that most of those 270k nodes are not intentionally duplicate. It is possible that there are duplicate ways as well. But it is not a big problem, it is something that could be fixed in a day. I could help with this but I would need very clear instructions what to look for, and what to do. Merging nodes may lead to duplicate ways that share exactly the same nodes (these can probably be removed automatically), but there might also be situations where you have one way that uses the nodes A, B1, C1 and one way that uses B2, C2, D (with B1 being at the same location as B2, and C1 at the same location as C2), so after merging nodes you'd then end up with the non-identical ways A,B,C and B,C,D... all this should be considered beforehand.
