Not supposed to be raw sewage, but water that’s gone through a treatment plant and is “clean” has to go somewhere.
I don't know how you read these articles and decide the problem is the release of water that's been through a treatment plant, but no, nobody is up in arms about that.
I think there’s problems everywhere on defining what “clean” means and monitoring it.
Again, these articles are not talking about water that has been treated. The words they're using are ones like "untreated" and "household sewage." If you want to drink it, though, please feel free; just wander on down to the bank of the Thames or Hudson.
