Can anyone interpret this list?

I feel like I'm missing something here. The EWG (Environmental Working Group) has a list of cities and data on water contaminants, but in the search it seems like the cities link to the utilities of other cities that aren't connected. For example in Michigan, West Branch gives links for Summit Township, and Highland Park. Cities pretty far across the state.

Might it be that these cities own the utilities of the other city? That doesn't seem right. Am I missing something here? Has anyone used this site before for environmental data? If not, are there any better resource that someone might recommend?

Thanks.

There actually seems to be two Summit Townships in Michigan (according to Wikipedia) one being only a couple counties west of Highland Park. So it's plausible they use the same water utility company.

I looked at the Texas info, which I'm more familiar with, and nothing seems out of the ordinary so far as which companies serve various cities, towns, areas.
