How to find quality groundwater in water-scarce areas more effectively by drilling wells?

Water is the source of life, and groundwater has an important role in supporting human survival, civilization, economic development, environmental maintenance, ecological health and landscape shaping because of its wide spatial distribution, its ability to be stored during abundant and dry seasons, and its quality, which is not easily polluted.

From the available archaeological evidence, China was the first country in the world to use groundwater (i.e., digging wells), and the earliest well discovered is located in the Neolithic period in Yuyao, Zhejiang Province, at the Hemudu site about 7,000 years ago. The invention of water wells meant a kind of liberation for human beings, and the character "Xing" in Xingtai, Hebei Province, is a combination of the characters for well and yi to form a meaningful character to commemorate the Yellow Emperor who led people to dig wells to extract groundwater, thus enabling human beings to no longer be limited to living near rivers, but to gather people to live with wells and promote civilization.


The recognition of the function of groundwater and the development of water sources have always accompanied the development of human productivity and the progress of civilization. The search for groundwater sources has gone through the way of association from spring outcrops, to intuitive experience summaries, and then to the formation of theories and guiding practices. In modern times, the discipline of hydrogeology has gradually formed, from the investigation and analysis of field stratigraphy and lithology, to the use of a single means of physical exploration, and then to the integration of integrated physical exploration technology and remote sensing and other technologies. As a result, water wells have changed from shallow wells in the early days to deeper wells, from vertical wells to horizontal and vertical cane wells, and from single wells to group wells for centralized water supply. The role of groundwater has also changed from a resource property for drinking, washing, irrigation, and industrial use, to an aesthetic factor for landscape creation, to a soul that sustains environmental friendliness and ecological health, and its importance is even more prominent today in the construction of ecological civilization.


However, groundwater has the advantages of being widely distributed, storable and of excellent water quality during abundant and dry periods, but at the same time has the shortcomings of uneven distribution and poor native water quality in some areas. Especially in the bedrock mountains, its distribution is extremely uneven, so much so that there is a "wall does not drill wells"; in the drinking water endemic areas and groundwater cycle stagnant areas, high-quality and low-quality groundwater aquifers in the horizontal and vertical interlocking and superimposed, but also to find water to increase the difficulty of drilling.


How to find quality groundwater more effectively in water-scarce areas to support the growing demand for water resources for social and economic development? What are the technical methods for finding and drilling wells in different areas under different conditions?

Ground water detector can be used for drilling wells to find the source of ground water effectively.The PQWTGT series is the eighth generation of our newly developed multi-channel electric exploration instrument based on the principle of natural electric field frequency selection method, which is widely used in the exploration and census of groundwater sources, geological formations, veins, mining channels, cavities, caverns, anthills, mining areas, dams, pipe surges, landslides and other fields. The ground water detector is integrated with a 5-pin system.

ground water detector

The ground water detector integrates five patented technologies invented by pqwt, including data acquisition system, data processing system, automatic mapping system, auxiliary analysis system and circuit system. It truly realizes multi-channel and multi-frequency simultaneous and synchronous data acquisition, which completely solves the influence of unstable factors brought about by the difference of natural electric field sources due to time, and greatly improves the accuracy and work efficiency. The instrument processes the collected data in real time, automatically draws curve, profile and 3D effect map in real time, and automatically analyzes the abnormal area, so as to quickly and effectively provide scientific basis for analyzing geological structure.
