if the corpse is in a location that I can feasibly observe within swimming distance, it's a problem.
so let's say there's a swimming pool shaped like an L, but one of the legs of that L is LOOOOOOOONG and the other is a short little stub.
If I am at the end of the long leg and the corpse is around the corner in the short stub, it would require me to swim all the way to the corner to observe it, and if that distance is longer than I can swim, then I will probably be ok.
If I am in the little stub of the L, and line of sight observation of the corpse is just a few strokes to the corner, I WILL NOT BE OK.
It's also a matter of relative mass.
If the pool had a drowned mouse in it, I will be sad. I might leave the water until the corpse is removed and then return to the water after it's gone through the filtration system for a little bit (a few minutes).
If the pool had a drowned squirrel in it, I will be alarmed. I will definitely leave the water and refuse to enter until the corpse has been gone for at least a few hours of filtration.
If the pool has a drowned raccoon, cat, fox, or small dog it it, I will be upset. I'm out of the water and concerned that nobody told me first, and I'm not going back in for the rest of the day.
If the pool has a drowned medium sized dog, coyote, baby goat, infant or toddler, or animal of similar mass in it, I'll be downright angry. I'm not going to that pool for a week, or maybe even a month.
Once the corpse in question reaches the mass of an adolescent human, I'm gone from that pool for the remainder of its open season.
If an adult human or larger died or was dumped in that pool, I'm never going to that pool again.
Working third shift where the majority of my duties are waiting for a phone to ring and babysitting an empty building lest it burn down while nobody's watching leaves me with more Noggin Time than most people have, so I appreciate you providing me with something to meditate upon :3
Raccoons also pose a greater risk than the others mentioned because their feces can contain a specific roundworm parasite’s eggs which are impervious to chlorine.
You would need to perform a much stricter disinfection.
If there are bodies in the water, I take them out of the water. Then I let the bodies hit the floor, let the bodies hit the floor, let the bodies hit the....
I think lokipagan has confounded the ability to see a corpse with whether you can see a corpse at the moment. In an L shaped pool I can see the corpse going in or out of the pool or if I near the bend. I would need a pool big enough that I don't have the physical ability to see it or discern corpse from flotsam.
We don't know, because theberserkingblacksmith didn't tell us if they were ok with this. You could also put the corpse in a water tank next to the pool with a shared water flow, but that's a different experiment. Or else sprinkle the corpse into the pool in tiny bits (i.e. micro corpses) invisible to the eye.
Plus, what if you were led to a leg of an L-shaped pool where, before you were in the building, a researcher might have put a corpse on the other leg of the L, in a way that you cannot see from your vantage point, you might decide to swim, or not swim, in said pool?
Here's the best question how many corpses does it take before people want to leave the planet
