In short, certain areas have radioactivity, which can contaminate ground water, even long after surface water has regenerated itself. Even floods, sink holes-all kinds of things, can cause water to become contaminated. Surface water can be contaminated easily, by farmers' chemicals, oil from vehicles, including watercraft. Anything that contaminates can get to surface water.

A long hole in the ground used to bring water to the surface is called a well. Wells are typically constructed by digging or drilling deep into the earth's surface until reaching underground water sources, allowing access to water for various purposes such as drinking, irrigation, and industrial use.
As long as the water entered above the ground surface level.
The nuclear fallout from Chernobyl contaminated the ground with radioactive particles, making it unsafe for agriculture and causing long-term health risks. It also contaminated surface water sources, leading to restrictions on fishing and drinking water consumption in the affected areas.

It remains as water vapor, or somewhere else in the water cycle. Some water has probably been stuck as ice in Glaciers for a long, long time, or perhaps stuck as water in the ocean for a long time, but it all still has the potential to evaporate and then become precipitation.
It's simply a long pipe that is bored into the ground in order to reach an aquifer. The water is then pumped into a surface reservoir.
As long as you like just be careful that no ground water gets under it as this will be able to float the pool upwards out of the ground and then it will probably become a jack hammer job
