VLF Geophysical Surveys: A Scientific Approach to Finding Water
A non-invasive, electromagnetic method of seeking reliable water supplies in
the
most optimal location.
Very Low Frequency (VLF) electromagnetic surveying is a non-invasive
geophysical
method that maps subsurface conductive structures - particularly fracture zones and faults in
bedrock -
before drilling begins. By identifying the most promising water-bearing features beneath your site,
VLF
surveys reduce drilling risk, eliminate guesswork, and help ensure successful borehole outcomes.
Whether
you're planning agricultural irrigation, private water supply development, or mineral
exploration, VLF
provides the critical subsurface intelligence needed to target your drilling investment with
confidence.
Key Benefits OF VLF SURVEYS
Choosing VLF geophysical surveying before committing to borehole drilling
provides significant advantages for clients seeking reliable water supplies:
Maximised Success Rate
VLF is
highly effective at identifying the steeply dipping, water-filled fractures common in
Scottish geology.
This precision greatly reduces the risk of drilling a dry hole, saving considerable time and
expense.
Non-Invasive and Fast
The
technique requires no digging, explosions, or ground disturbance. Data collection is rapid,
allowing
large areas to be surveyed efficiently, minimising disruption to your property or
operations.
Cost-Effective Site Siting
Compared
to the cost of exploratory drilling, a VLF survey is a small upfront investment that
delivers
high-confidence targets, ensuring that drilling resources are spent in the most optimal
location.
Detailed Subsurface Mapping
The method
provides valuable information on the depth, direction, and lateral extent of subterranean
features,
allowing for optimal borehole design and anticipated water yield.
Scientifically Backed Certainty
By
utilising established principles of electromagnetism, we ensure that your borehole siting is
based on
quantitative data rather than traditional, less reliable methods.

APPLICATIONS & USE CASES
The VLF method has proven successful across Scotland and beyond in
diverse
hydrogeological settings:
Agricultural Irrigation
Maps deep regional fault zones to deliver high-yield boreholes where
traditional shallow wells fall short of irrigation demands.
Residential/Commercial
Pinpoints productive fracture intersections in complex geology,
providing
reliable private water supplies where traditional exploration would be costly and uncertain.
Mineral & Quarry Exploration
Maps geological contacts and fractured zones to support mineral
exploration,
offering dual-purpose value beyond water supply applications.
