15 feet.
The water table in Nova Scotia is usually found within about 5 m (15 feet) of ground surface, but can be deeper in areas with higher topography, such as the Cape Breton Highlands.

How do I find out how deep the water table in my area?
The USGS National Water Information System (NWIS) has depth-to-water measurements made in the present and the past. A convenient way to find data for your area is by using the NWIS Mapper and selecting “Groundwater Sites” in the menu on the left.
How deep do you have to dig to reach the water table?
Although the water table varies throughout the Oglalla Aquifer, it is generally 15 to 90 meters (50 to 300 feet) below the land surface.
What is underneath the water table?
Underneath the water table is the saturated zone, where water fills all spaces between sediments. The saturated zone is bounded at the bottom by impenetrable rock. The shape and height of the water table is influenced by the land surface that lies above it; it curves up under hills and drops under valleys.
What time of year is water table highest?
During the late winter and spring when accumulated snow starts to melt and spring rainfall is plentiful, water on the surface of the earth infiltrates into the ground and the water table rises.
Can you find water anywhere if you dig deep enough?
There is water somewhere beneath your feet no matter where on Earth you live. Groundwater starts as precipitation, just as surface water does, and once water penetrates the ground, it continues moving, sometimes quickly and sometimes very slowly.
How do you know if there is water underground?
The ground penetrating radar (GPR) system is used for underground water detection. GPR is a promising technology to detect and identify aquifer water or nonmetallic mines.
Can I dig my own water well?
The short answer is that water rights are mostly handled at the state level. And while some states only allow licensed well contractors to perform any type of drilling at all, many states will allow a homeowner to dig a private well on his/her own property as long as a permit is applied for and approved.
How do I know if my water table is high?
Signs of a High Water Table
- Basement Flooding:
- Standing Water:
- Damp Wooden Floors & Walls:
- Septic System Failure:
- Foundation Shift:
- Humidity Issues:
- Yard Drainage:
- Natural Drainage Systems:
How long does it take for rainwater to reach the water table?
Permeable surfaces, such as sand and gravel, allow up to 50 percent of precipitation to enter the soil. Rainwater can take years or even decades to reach the water table.
Does the water table move down in dry weather?
In any one place the water table usually rises with increased recharge from precipitation and declines in response to seasonally dry weather, drought, or excessive pumping of ground water.
Is groundwater safe to drink?
Typically, groundwater is naturally clean and safe to drink. Because the soil on top acts as a filter, groundwater is usually free of micro-organisms that may cause disease. However, groundwater can become contaminated if the casings or caps for wells are not installed in the correct way.
How long does it take for a water table to go down?
Generally, water seeping down in the unsaturated zone moves very slowly. Assuming a typical depth to water table of 10 to 20 metres, the seepage time could be a matter of minutes in the case of coarse boulders, to months or even years if there is a lot of clay in fine sediment.
How deep should a well be for drinking water?
100 feet deep
For drinking water wells it’s best to be at least 100 feet deep so that surface contaminants cannot enter the well. The average well depth for private homes is between 100 to 800 feet [2]. You may need a deeper or shallower well if your area has different geology than another region of the country.
Can you dig a well anywhere?
You probably can drill your own well on your property. You, of course, would have to contact your local building department to see if there are any regulations that must be followed. Some states and cities may still charge you for the water that’s pulled from your land, but that’s a debate for another day.
Which trees indicate underground water?
Some phreatophytes have a low tolerance for salt, indicating freshwater. This can be a valuable guide to the location of drinking and agricultural water in arid and semiarid areas. Examples of phreatophytes include Welwitschia and mesquite: Prosopis glandulosa.
What is the deepest you can drill for water?
Drilling a Water Well for household use will usually range from about 100 feet to 500 feet deep, but… When drilling a new well for your home or business, the depth of the well depends on the geology and underground water levels of the area.
How long can a water well sit unused?
How long a well can sit unused will depend on the construction and the surrounding area where it resides. Most wells that have sat dormant for more than a year should be inspected and treated as the condition demands. What is this? Certain materials will erode faster and make the well structurally unstable.
Do wells run out of water?
When a well “runs dry” it doesn’t mean that the well will never produce water again. Aquifers can recharge through a combination of more precipitation and less pumps pulling water out of that aquifer. Sometimes wells can run dry permanently, but that is quite uncommon.
How long does water stay in deep groundwater?
10,000 years
Ground: When the water precipitates to the earth, it can stay in a few places. If it comes to the ground, it will likely hang out there for a month or two, though some of it will trickle down as shallow groundwater, where it can stay for 200 to 300 years. Deep ground water can remain underground for 10,000 years.
Do deeper wells mean better water?
Well depth can affect both the quality and quantity of water pumped from a well. As shown in figure 2, the quality of water in a well is influenced by the land use activities that take place in its recharge area. As for quantity, a well that is not deep enough to reach the water table will yield no water at all.
