Every three months our Kids Corner will be changed to answer a different water-related question. Here is what we tell them. Artesian water is water that is pumped from an artesian well. Not all underground wells are artesian wells.
Some underground wells are shallow wells .
Artesian wells are located in lower, confined aquifers . Water enters the aquifer from the highest level of the aquifer, and when a well is drilled at a lower level, pressure from above forces the water out through the artesian well. Most domestic wells are shallow wells, located in unconfined aquifers . Water levels rise and fall according to the amount of rainfall in the area. Shallow wells are more easily contaminated because they are less protected from things such as oil spills, chemical pollutants .
