What Is an Artesian Well?

Artesian wells are formed from artesian aquifer. Artesian aquifers are confined aquifers that hold groundwater underground using pressure. Because the water is surrounded by non-permeable rock, it has nowhere to go but up towards the surface. Groundwater from an artesian aquifer will naturally rise from the aquifer. In some cases, the pressure is strong enough for the water to reach the surface. 

However, unlike wells that are dug by hand or drilled deep into the ground, artesian wells may require less digging because of how close the groundwater is to the surface.

Can You Drink From an Artesian Well?

Yes, you can drink from an artesian well. Artesian water is generally safe and clean due to natural filtration through rock layers. However, regular testing is crucial to ensure the absence of contaminants, as with any water source. In contrast, traditional wells may need more rigorous purification to meet safety standards, depending on their depth and surrounding environment.

What Happens in an Artesian Well?

In an artesian well, groundwater is pushed upward by the pressure from the surrounding impermeable rock layers, often requiring minimal pumping to bring water to the surface. In traditional wells, water extraction relies heavily on mechanical pumping due to lower natural pressure.

How Deep Are Artesian Wells Usually?

Artesian wells can vary in depth but are often between 100 to 1,000 feet deep, depending on the aquifer's location and pressure. In contrast, traditional wells may need to be drilled much deeper to access groundwater, particularly if the water table is far below the surface. The required depth for artesian wells is generally less, leading to potential cost savings in drilling.

Can Artesian Wells Be Drilled Anywhere?

No, artesian wells cannot be drilled anywhere. They require specific geological conditions, such as the presence of a confined aquifer under pressure. Traditional wells offer more flexibility in location since they rely on reaching the water table rather than specific pressure conditions. However, the best location for any well depends on various factors, including accessibility, potential contamination, and ease of drilling.

How Do You Know Which One Is the Best for Your Home?

There are several factors to consider when deciding which type of well you should dig: 

• How deep or shallow each type of well needs to be dug.
• The amount of natural pressure from the artesian aquifer.
• The number, size, and types of pumps you may need for your well.
• The amount and type of rock.
• The best location for the well. This includes figuring out what location is most convenient, what possible contaminants need to be avoided, and what location is the easiest to dig.

These factors, along with any other ones unique to your property will help decide what is the best type of well for you.

What Are the Pros and Cons of Artesian Wells?

While each well is different based on the property’s features, here are some general pros and cons of an artesian well:

Pros:

• May cost less to build than wells dug by hand or drilled into the ground.
• May require fewer mechanical parts to be installed and maintained. 
• Water is naturally filtered through rocks when coming up to the surface.

Cons:

• Location may not be convenient or be susceptible to contaminants. 
• Constant flowing water may damage pipes and other mechanical parts.
• Pressure may not be consistent or provide enough water.
