Many people suspect that having a deeper well automatically means the water will be more plentiful, and of better quality, but that’s not always the case.
In fact, the depth of your well should be suited to a variety of factors specific to your land and the patterns of groundwater in your area.
Are deeper wells better?
Increases Water Supply: Shallow water wells are less than 50 feet deep. Water at this depth fluctuates more often. By deepening the well, you are creating more storage space for larger volumes of water that spring from underground. Better Water Quality: Shallow wells are more susceptible to surface contamination.
How deep does a well have to be for drinking water?
On the surface, the casing will be about 12 inches above the ground. Throughout New England, water is often found at about 300 feet, but wells for household use usually range from about 100 feet to 500 feet deep. There are some places, however, where a well can be more than 1,000 feet deep.
Can a water well be drilled deeper?
A well is an engineered hole in the ground via which ground water can be brought to the surface. Drilling machines can drill to great depths. Deeper wells usually cost more than a shallow well to construct in the short-run. The well must therefore be drilled deeper than the lowest expected elevation of the water table.
Why do deep wells have clean water?
Water quality in a deep well usually changes more slowly than in a shallow well. That’s because groundwater does some mixing as it moves through the aquifer. A spill a mile away from your deep well in the Basin and Range aquifer might be substantially diluted with clean aquifer water before it gets to your well.
How far down is groundwater?
Groundwater may be near the Earth’s surface or as deep as 30,000 feet, according to the U.S. Geological Survey (USGS).
How many years does a water well last?
Water wells use pumps that are used to drive water from the ground to your home. These pumps determine the lifespan of your well. Submersible pumps that are commonly used in many wells usually last from eight years to ten years. With proper maintenance and care, the lifespan can be increased to fifteen years.
Can you drill for water anywhere?
The depth of the groundwater supply may dictate how, and if, you can drive or drill your well. For good potable water, you will have to go deep enough. Acceptable water will usually require going at least 30 feet down, but better water will usually be even deeper. Never drive or drill a well in a marshy, wet area.
Can I drill my own well?
You can drill your own shallow water well using PVC and household water hoses. It is a cheap and effective way to dig your own shallow water well. The water well drilling methods described here work well in digging/drilling through dirt, and clay, including really hard clay.
Can you drink well water?
Most well water is safe to drink, but there can be health risks associated with well water used for drinking. Well water may contain microorganisms and chemicals that could make you sick. That means it’s up to the well owner to ensure that well water is safe to drink.
