Groundwater monitoring and its importance
The water found in the spaces between rocks and soil beneath the Earth's surface is known as groundwater. Water that collects above the Earth's surface, such as rivers, streams, lakes, and oceans, is called surface water. Groundwater accounts for approximately 30% of all fresh water on Earth, while surface water accounts for approximately 70%. Groundwater is an important source of water for public water supplies and private wells around the world as it feeds wells and springs. Groundwater monitoring is very important, and the groundwater monitoring system developed by JXCT can be used for online monitoring.
Most of the fresh water is located in underground aquifers and soil moisture. Because groundwater feeds streams, rivers can continue to flow even in the absence of precipitation. Both groundwater and surface water may be used by humans. Groundwater accounts for about 98 percent of the world's available freshwater, about 60 times more abundant than that found in lakes and streams. Groundwater is an important source of drinking water that keeps society running and could be disastrous if depleted.
What is the water cycle?
The hydrological cycle, commonly known as the water cycle, is a flow diagram of how water circulates in the environment. Water molecules remain the same whether they are solid, liquid or gas. The process of liquid turning into water vapor occurs when water droplets in the ocean evaporate.
Water vapor may evaporate from water surfaces, land surfaces and snow fields and enter the atmosphere. Condensation is the mechanism by which water vapor in the air turns into liquid water. Condensation is water that collects outside a glass of cold water. Condensation is the opposite of evaporation.
Clouds form when water vapor condenses on tiny particles of smoke, dust and salt crystals. After a while, the water droplets combine with other water droplets and fall to the earth in the form of precipitation (rain, sleet, snow, hail, dew, and frost). Once precipitation reaches Earth, it either enters aquifers as groundwater or remains above the surface as surface water.
The water cycle is affected by pollutants
Humans, animals and the environment all benefit from the protection of the water cycle. Contaminants can be carried away by the water at any time and transported to later stages of the cycle. During periods of heavy rainfall or snowmelt, trash, sediment and invisible pollutants such as fertilizers, oils, pesticides and other chemicals are transported onto land and into downstream water bodies. Industrial emissions can enter the clouds through the air, causing acid rain. Pollution from various sources accumulates within watersheds, destroying organisms that come into contact with them. Therefore, groundwater monitoring is very important, especially water quality monitoring.
How to solve water pollution
A healthy ecosystem naturally filters some pollutants, but only to a certain extent. Natural filter zones include permeable soil, vegetation, and wetlands that absorb water and toxins to create "sinks" that slow water flow.
Over the past few decades, considerable research has been devoted to developing reliable and efficient methods to detect pollutants with minimal operating costs and energy. In both quantitative and qualitative terms, recent advances in spectroscopic and biosensor methods have increased detection sensitivity.
unprotected groundwater
Groundwater can be polluted and unprotected by residential, municipal, commercial, industrial and agricultural activities due to many natural resources or various human activities. Therefore, water quality monitoring is necessary, not only for living organisms, but also for future sustainable development
Laboratory water quality analyzer
Laboratory water quality analyzer is widely used in water quality testing institutions, enterprise sewage self-test, dyeing and textile industry, sewage treatment and other fields.
Laboratory water quality analyzer (laboratory water quality testing equipment) adopts sealed catalytic digestion, and then adopts colorimetric measurement. Advanced cold light source, narrow-band interference technology and microcomputer automatic data processing. According to the data, the concentration value of the printed sample is directly displayed. Laboratory water quality analyzer can monitor water quality COD, BOD, ammonia nitrogen, turbidity, total phosphorus, total nitrogen, chroma, suspended matter and more than 50 monitoring items. Can help you better understand the water quality
