Drilling a well is an expensive and highly technical operation, but with water finding

technologies, such as the seismoelectric or electroseismic method, finding water has

never looked so cool.

The Low Down

Finding water is a bit like detective work; in order to find it, surveyors must first find

traces – that is clues – of it. Fortunately, these water detectives have super high-tech

gadgets to help them do their work, such as utilizing the seismoelectric electroseismic

method. But what does that mean? It’s actually quite simply: using seismic waves to

create electromagnetic fields in soils and rocks and otherwise “water-less” landscapes,

surveyors are able to detect what are known as water indicator, such as hydraulic

conductivity and uniform or irregular permeability, and are thus able to search out

favorable conditions for groundwater development.

Finding Traces

Like any good detective, the water surveyor or hydrologist has to first lay the ground

work before making assumptions, must find and assess clues and make reasonable

deductions based on the information at hand. As the USGS Water Science School points

out, of all the clues that lead to water, “rocks are the most valuable clues of all. As a first

step, in locating favorable conditions for groundwater development, the hydrologist

prepares geologic maps and cross sections showing the distribution and positions of the

different kinds of rock, both on the surface and underground.” Combining “old school”

strategies with new technologies, water surveyors are able to find groundwater quicker,

easier and faster than they ever were before! This is critically important to the process

of drilling, as drilling is a very expensive operation that requires highly specialized


Natural Clues

In other words, the hydrologist finds and surveys the

characteristics of rocks to determine where the water

is. However, different rocks tell different stories.

Sedimentary rocks, for example, may indicate the

favorable conditions for lengthy and extensive

aquifers. Cracked and jagged rocks, on the other

hand, might indicate large and deep openings

favorable to carry large quantities of water. Plants and localized vegetation also work as

“clues” to finding water, as plants that are known to require high levels of moisture and

hydration will, of course, stay close to sources of water.

X-Ray Vision

For the high-tech Sherlocks, however, surveyors may not need to assess the

characteristics of area-specific rocks or plant-life. In fact, with the new seismoelectric

technology, surveyors are now capable of creating 2D models of what’s underground.

It’s kind of like having x-ray vision, and significantly reduces the time spent finding the

best place for wells. As this technology continues to develop, surveyors are able to find

water in more cost efficient and time effective ways.


At times, high voltage power sources can get in the way of accurate readings and the

seismoelectric method is only effective up to depths of 1500 feet. When technology fails

to find water, however, the expert water finders go back to the basics – looking at rocks

and vegetation.
