Having never really thought about the inner workings of the Earth's water table, oddly enough, I would have guessed that the water in it was gently moving around, kinda like a stream.

And that yer well would go down into it, then your water pipe down further, so that the water you're drawing up would always be changing due to the water moving around.

This isn't the case?

The water is usually just sitting there, all stagnant and more pongy than a KW red?
