GEOLOGY

Detailed explanation-1: -A “well” is simply a hole dug deep enough that it penetrates below the water table and therefore fills up with water. To retrieve the water, old wells used simple buckets on ropes.

Detailed explanation-2: -Dig until water starts entering the hole, or to a maximum depth of 4 feet. Allow the hole to settle, and observe if water fills the hole within 1 hour. The level that water enters and fills the hole, is the water table level.

Detailed explanation-3: -To make things more difficult, as they drill deeper into the Earth, they’ll encounter extreme temperatures, possibly in excess of 1, 000 degrees Fahrenheit (538 degrees Celsius), and fantastic amounts of pressure-as much as 4 million pounds per square foot in the vicinity of the mantle.
