GEOPHYSICAL TEST METHODS
Geophysical test is often used as part of the initial site exploration phase of a project and/or to provide supplementary information collected by widely-spaced observations (i.e., borings, test pits, outcrops etc.). Geophysical testing can be used for establishing stratification of subsurface materials, the profile of the top of bedrock, depth to groundwater, limits of types of soil deposits, rippability of hard soil and rock, and the presence of voids, buried pipes, and depths of existing foundations. Data from geophysical testing should always be correlated with information from direct methods of exploration.

There are a number of different geophysical in-situ tests that can be used for stratigraphic information and in the determination of engineering properties. The two most common methods are:

Seismic Methods
Electrical Methods

SEISMIC METHOD
The seismic method is an active form of geophysical
surveying that uses elastic waves to investigate the subsurface. The waves are created by a source and propagate through the subsurface before being recorded by detectors that measure deformation of the ground.
Most seismic surveys use sources and detectors located on, or near, the Earth’s surface.

ELECTRICAL METHOD
Electrical geophysical prospecting methods detect the surface effects produced by electric current flow in the ground. Using electrical methods, one may measure potentials, currents, and electromagnetic fields that occur naturally or are introduced artificially in the ground. In addition, the measurements can be made in a variety of ways to determine a variety of results. There is a much greater variety of electrical and electromagnetic techniques available than in the other prospecting methods, where only a single field of force or anomalous property is used. Basically, however, it is the enormous variation in electrical resistivity found in different rocks and minerals that makes these techniques possible.

Electrical Properties of Rocks

All materials, including soil and rock, have an intrinsic property, resistivity, that governs the relation between the current density and the gradient of the electrical potential. Variations in the resistivity of earth materials, either vertically or laterally, produce variations in the relations between the applied current and the potential distribution as measured on the surface, and thereby reveal something about the composition, extent, and physical properties of the subsurface materials. The various electrical geophysical techniques distinguish materials through whatever contrast exists in their electrical properties. Materials that differ geologically, such as described in a lithologic log from a drill hole, may or may not differ electrically and, therefore, may or may not be distinguished by an electrical resistivity survey. Properties that affect the resistivity of a soil or rock include porosity, water content, composition (clay mineral and metal content), salinity of the pore water, and grain size distribution.

ADVANTAGES OF GEOPHYSICAL TEST
Geophysical testing offers some notable advantages and some disadvantages that should be considered before the technique is recommended for a specific application. The advantages are summarized as follows:

Many geophysical tests are non-invasive and thus offer significant benefits in cases where conventional drilling, testing, and sampling are difficult (e.g., deposits of gravel, talus deposits) or where potentially contaminated soils may occur in the subsurface.
In general, geophysical testing covers a relatively large area, thus providing the opportunity to characterize large areas with few tests. It is particularly well-suited to projects that have large longitudinal extent compared to lateral extent (such as for new highway construction).
Geophysical measurement assesses the characteristics of soil and rock at very small strains, typically on the order of 0.001 percent thus providing information on truly elastic properties.
For the purpose of obtaining information on the subsurface, geophysical methods are relatively inexpensive when considering cost relative to the relatively large areas over which information can be obtained.

What are the benefit of Drilling borehole?

A water borehole is essentially a well: not the ornamental, whimsical kind that you throw pennies in to make a wish, but the practical, useful kind that actually makes day-to-day life better for you, for the environment and for your bank balance.

Here are three of the key benefits that a domestic or commercial borehole can give you:

Self-Sufficiency:

Whether you’re ecologically or financially motivated to live in self-sufficient and sustainable ways, equipping your home or business with a borehole is a step in the right direction.

We all have a responsibility to use natural resources responsibly and when you use a borehole, that’s exactly what you’re doing.

The water that borehole produce is sitting dormant in the ground, naturally accumulating from rainfall and underground springs. Making use of it means that you’re simply utilising an unused groundwater resource.

It also means that you have access to a reliable water supply which won’t be interrupted by problems caused by things beyond your control such as leaks or poor connections from antiquated pipe systems.

Save Money:

Research shows that in the last decade, water prices have increased by up to 82% in some areas of the country and unsurprisingly, so have the profits of their suppliers.

By drilling a borehole, you are tapping into your own private water supply and can cut out a large percentage of those costs. If you opt for an advanced system with filtration, you can supply drinking water too and end your reliance on a utility provider and cut the costs out altogether.

Every household is the UK has the right to extract up to 4400 gallons or 20 cubic metres of water from their own land, for free, every single day.

To put that in perspective, one “fully grown apple tree can drink 4,400 gallons of water per year” and poplars, willows and oaks need significantly more.

4400 gallons of water from a utility provider would cost approximately £40 but that’s just for the water. On top of that you’d also be expected to pay standing and sewerage charges which are likely to cost an additional £70 on average.

When you use the water from your own private supply, apart from the initial borehole drilling costs, making use of it will cost you nothing more than a small fee for the electricity used to power your private well.

This means that if you regularly water your garden trees or vegetable patch, wash your car or farm vehicles, supply ponds or feed animals and livestock, then over the course of a year your savings could be substantial.

Make Money:

In the short term, having access to your own water wells can save you money and really add value to your property.
