Anyone notice anything...odd... about the tap water lately? Smell or taste?

I noticed on Saturday 2nd December, that my tap water smelled and tasted weird. I didn't think much of it but then later, I noticed the shower water also smelled weird. So I went to a pool to shower and it smelled weird there too. And then on Monday, I had some water at a bar and it smelled weird there too. I've asked a few people if they've noticed anything about it, but they haven't. So I'm wondering if I'm going insane or something.

Ever since then, it's become worse and worse and I don't know why. The smell is almost unbearable.

I don't know what it smells or tastes like but it's gross.

Anyone else notice anything about the water?
