The noise is the main issue. I'm not american, but one of my relatives works in bernie sanders's office, and one of my friends (30ish) is involved somehow in the democratic party not sure how exactly. And what I hear from them is that the issue is mostly the noise only. The water aspect was there but that was mostly disruption during construction.

They are powering it with turbines right, so if its next to your house it sounds like you're permanently in on the airport tarmac. Not great. I saw a video (not on the internet, but from them). It was pretty annoying. But it makes sense, there is no way a power delivery system in a developed country adapts so fast to such intense energy needs. Here in india, many 250Mw datacenters are put in places where a proper grid connection is itself coming for the first time, so the same problem is not there. And frankly there are way more noisy industries in poorly zoned mixed-industrial-residential areas here for generator noise to even matter.
