The Nimitz had a similar problem several weeks ago
To me, the worst thing health-wise I ever encountered on a carrier was during a week or two stint on the USS Lexington in Pensacola.
I was berthed in some compartment that must have had a bunker fuel tank venting into it. I couldn’t sleep the entire time I was there, I would drift into semi-sleep then wake up fully feeling feverish and nauseous, sweating, with the taste of fuel in my mouth and nose. Ugh. It was terrible.
The Lexington was, at that point, probably a 35 year old ship, and run down.
Of course, for disgusting, was when I was on the JFK, there was always water on the deck in the heads, most of it was from showers stalls I supposed. Of course, I had the stupid flip-flops on my feet. But one day the water was deeper, which meant my bare feet were being immersed in the water.
As I was at a sink, my vague degree of distaste at the water I normally felt turned into real disgust when, as brushing my teeth, looked down to see pieces of soggy toilet paper in varying degrees of disintegration.
I stopped brushing my teeth as my eyes fixed on it, and my mind began to dimly form the logic “Where there is toilet paper in water, there is...” and my eyes found the source of the water. There was a toilet, broken into pieces, laying on the deck. Looking closer, I noticed there were turds floating around in the water! Gaaaaaaasaaahhhh!
