Water scarcity is one of the most far-reaching and serious impacts of climate change, and already millions of people around the world lack direct access to fresh drinking water. Humanitarian organizations and geologists are using water detectors to locate underground water reservoirs and aquifers that were previously hidden from view. The innovative OKM technologies effectively assist in water detection, cavity detection and further ground investigations.
In Africa alone, more than 300 million people lack adequate drinking water supplies and rely on human aid organizations for assistance. Droughts, intensified by climate change, are fostering increasingly rapid desertification, reduced soil fertility, lower groundwater levels and drying up water resources. According to an estimate by the U.N. Development Assistance Program, as many as 1.8 billion people worldwide will suffer from direct water shortages by 2080. Technological water detection is becoming an increasingly important tool for finding and accessing new sources.
Facilitating Water Detection with Water Detectors
Scientists emphasize that - in addition to effective and comprehensive measures against climate change - water scarcity can be effectively reduced primarily with new technological and innovative tools for water detection. These include water detectors such as those from OKM, which can effectively facilitate water search, cavity detection and ground investigation using a Schlumberger-based geoelectrical measurement method.
Supporting Water Detection for Human Aid Organizations And Geologists
Today, aid organizations and geologists are already using water detectors in countries such as Kenya, Ethiopia and Mali to locate underground lakes, known as aquifers, and previously hidden ground water resources. Ground investigation for water detection and cavity detection, such as by the OKM GeoSeeker, determines the exact soil resistance and thereby indicates whether water deposits exist in the underground. Aid organizations can then initiate further measures to access the precious sources.
OKM GeoSeeker Supports Aid Organizations in Mali in the Search for Water
Back in December 2017, OKM handed over a GeoSeeker to the aid organization "Aktion Pro Afrika e. V." in Mali, which has since been used successfully to search for water and cavities. The exact execution of the measurements and the simple and flexible handling of the OKM GeoSeeker facilitate the water detection of the aid organizations enormously and save the experts other lengthy and complex processes for soil investigation.

Innovative Technology Optimizes Success in Water Detection
Both the OKM GeoSeeker and OKM GeoSeeker Mini feature innovative technology for water detection, cavity detection and soil investigation. Three measurement methods are possible with the pre-installed software applications:
- In the Active measurement, current is conducted into the ground via two electrodes and, with the help of two additional electrodes, the voltage drop is measured at previously defined measuring points. Accurate measurement is considered to be very precise and is ideal for water search, cavity search and soil investigation. If the search is to be carried out more quickly, a fast Active measurement can also be carried out.
- The Passive measurement is mainly used to detect flowing water in the subsurface during the water detection. No current is conducted into the ground, but the electrodes detect the naturally occurring voltage during the ground exploration.
