Whenever you let water run, you make your home part of the greater water system, which eventually starts with springs and ends in an ocean. You have a tiny side arm of a river in your sink!

Sort of. The septic tank drains into the ground and the well pumps it out of the ground. They’re not that far apart so I imagine after a few decades some pee filtered by groundwater ends up back into the well. But I’m no expert.
Sort of an expert here: Could be decades, could be months, could be days.
It all kinda depends on geological conditions (as well as the condition of your septic tank). Groundwater flow rates can be very different. If you have sandy soil, it will be a lot quicker than if you have a lot more silt or clay.
It should be no less than 50 days though, because in that timeframe it is usually assumed, that microbial activity in the soil as well as adsorbtion can remove most of the harmful substances.
I hope whoever built that system took that into account, though.
