Underground Water Sources And Best Soils For Wells

Posted on: 10 September 2021

When you need a well, you will need to locate an underground source of water. Sometimes, your local well company is knowledgeable about the groundwater in your area. Other times, you may need to hire an expert to find the best place for a well. Your land's soil type may also be a hindrance. Here is more information about underground water sources and what soils are the best for a well.

What Are External Signs of Groundwater?

The first step in finding water is to look at the surface. Signs of water can be everywhere, even if the land looks dry. One way to spot water is to look at the plants on your land. Some plants have deep roots. Others have shallower roots but require a lot of water. The land's topography is also another clue. Valleys are a great place to search for water because water rolls off from the surrounding hills.

What Is an Aquifer?

An aquifer is defined as sediment and water-permeable rock that hold water. Contrary to popular belief, it is not an underground lake, river, or spring. However, that doesn't mean that you don't have any of those under your property. Most people do not, and that is not where people usually get their well water.

Aquifers can be confined or unconfined. Unconfined aquifers are those directly recharged by rain or snow. Confined aquifers are those blocked from the surface with a layer of deposits such as impermeable clay. Most wells are dug in unconfined aquifers.

What Is an Artesian Well?

An artesian well is a well that needs no pumping or pressure to bring it to the surface. Most of these wells are much deeper than traditional wells. They can be so deep to reach into a confined aquifer or spring. Many people find these wells beneficial because they don't need filtering or pumping. They also have high mineral content.

What Soils Work Best for Wells?

Soils that allow for pockets of water to accumulate are the best soils for a well. Artesian wells are often found surrounded by limestone. Sandstone and gravel are also ideal substrates for wells. The most suitable soil should be loose and hold water. Some types of clay are not favorable for wells. Their particles often bind together to create a barrier.

When your property has difficult terrain, finding a well can be challenging. Soil, rocks, and low water tables can make finding a well more difficult. That's where hiring an expert can help. An expert will locate the best place to place your well, so you don't spend unnecessary time digging in an unproductive spot.
