Homeowners who are planning to build a new home in an area where no public water source is available usually choose to have a water well drilled on their property. While owning and managing your own water source may sound a bit scary at first, it can be comforting for novice water well owners to know that, according to the United States Environmental Protection Agency (EPA), more than 13 million homes are already safely using a private water well for their home's water supply. If you are about to join these millions of water well owners, the following information can be helpful.
What is the water source for a private water well?
Groundwater that accumulates far beneath the earth's surface is the source for the water drawn up through a private water well. The groundwater forms as rain and other sources of moisture seep down through the layers of soil, rock, and other materials. Each layer removes contaminants, and by the time the water reaches the underground aquifers and lakes, it is pure and safe to drink.
Does well water have to be treated or purified?
The reason that most public water sources rely on chlorination and other purification processes is because the water they provide to their customers is usually sourced from surface water. Surface water usually comes from rivers, lakes, or large above-ground holding ponds, making it possible for contamination to occur.
Water from a water well, however, does not have the same potential for contamination, making the addition of harsh purification chemicals unnecessary. Some homeowners will need to install some type of filter or purification method on their water wells if water testing results indicate it is necessary to do so.
How deep must a water well be?
The actual depth of a drilled water well can range from depths of around a hundred feet to depths of more than a thousand. In most areas, wells will fall somewhere in the middle of those figures. The actual depth of the well is determined by the depth required to reach a suitable aquifer. The geology of the land and surface issues, such as rock formations, hills, and mountains, can also affect the depth of the completed well.
