Urbanization and chloride—a concern for streams and groundwater. Chloride is a major component of dissolved solids. The use of road salt—sodium chloride, the same chemical as table salt—for deicing is a major manmade source of chloride to surface water and groundwater.
Chlorides are widely distributed in nature as salts of sodium (NaCl), potassium (KCl), and calcium (CaCl2). The taste threshold of the chloride anion in water is dependent on the associated cation. Taste thresholds for sodium chloride and calcium chloride in water are in the range 200–300 mg/litre (2).
Chlorine is widely used in water treatment as a disinfectant or biocide. Chloride is present in various rock types in lower concentrations than any of the other major constituents of natural water. Main chloride bearing minerals occurring in igneous rock are feldspathoid sodalite and the phosphate mineral appetite.
Chloride is a naturally occurring element that is often associated with elevated sodium levels in water. This glossary discusses the risks and effects of drinking water with a high chloride content, how to tell if your water contains chloride, how to protect your family from chloride, and more. What is Chloride?
What do chlorides in water tell us? Learn about chlorides in water, their origins, and their impact on health and the environment. This comprehensive guide explains chloride levels, sources, and effective water purification methods like reverse osmosis to ensure safe drinking water.
The good news is that chlorides can easily be removed from water with either a reverse osmosis system or a distiller. Reverse osmosis works by passing water through a semi-permeable membrane that separates pure water into one stream and salt water into another stream.
Chloride concentrations of between 1 and 100 ppm (parts per million) are normal in freshwater. Chloride ions come into solution in water in underground aquifers, geological formations that contain groundwater. In coastal areas, chloride from saltwater aquifers, sea spray, and coastal flooding can also find its way into freshwater waters.
There is no health-based guidance for chloride in drinking water, but there are health implications for consuming sodium. Sodium and chloride concentrations in water are often related since sodium chloride (NaCl) is the most common type of road salt being applied in the winter.
Chloride, a key component of road salt, is soluble, highly mobile in water, and, at high concentrations, can be toxic to aquatic vegetation and wildlife. USGS scientists have been analyzing temporal, seasonal, and environmental trends in chloride concentrations across the U.S. to determine the effects that road salt may be having on water ...
How Does Chloride Get Into Drinking Water? Chloride occurs naturally in our environment, particularly in bodies of water. It’s often found alone as salt or sodium chloride, but it often appears alongside calcium and potassium, too.
