The standards differ because different usages require different standards. For example, drinking water requires chemical treatment and biological treatment, while water for steam generation (Industrial) requires separation of ion and dissolved gasses to prevent either corrosion or fouling. If the water is used for processes, the treatment will focus on removing impurities that have great impact on the balance of the process. Another reason why the standards are different is because of the treatment cost that differs based on each standard.

How can you measure water purity ?
Federal standards for city-supplied drinking water are governed by the Environmental Protection Agency (EPA) under the Safe Drinking Water Act, which sets limits on various contaminants. Commercial bottled water, regulated by the Food and Drug Administration (FDA), must meet the same quality and safety standards as tap water but is subject to different testing and monitoring requirements. Additionally, bottled water may be subject to labeling regulations that differ from those for tap water.
The purity of the lake water is questionable.You can tell the purity of your tap water by purchasing a home water testing kit.
Purity.
It's pretty difficult to explain a detailed process in a short comment, but the basic steps of testing water purity are: Taking a sample of the water, usually 1 liter/quart Adding various chemicals to the water to make the substances in water easier to analyze Testing the water with special equipment using absorption or spectroscopy to give you a purity reading If you're wondering about how you can perform a water purity test yourself, it's not really possible unless you have specialized equipment and lab facilities available to you.
Purified water has undergone a process to remove impurities and contaminants, such as chemicals, bacteria, and minerals. This process typically involves filtration, distillation, or reverse osmosis to ensure the water meets certain purity standards.
A sacred water lily is called a lotus. It is known for its spiritual significance in various cultures and religions, symbolizing purity, enlightenment, and rebirth.
No, the purity of water is not measured in cusecs. Cusec (cubic feet per second) is a unit of flow rate, not a measure of water purity. Water purity is typically measured using parameters such as levels of contaminants, minerals, pH, and dissolved solids.
Standards for raw water quality can typically be found in government regulations, environmental protection agencies, or water resource management organizations. These standards outline the acceptable levels of various contaminants and parameters in raw water to ensure it is safe for human consumption and ecosystem health. Additionally, international organizations such as the World Health Organization may also provide guidelines for raw water quality standards.
The purity of water is inversely related to its conductivity. Higher purity water has lower conductivity because impurities in water, such as minerals and ions, increase conductivity by allowing the flow of electric current.
Water treatment can improve the quality of drinking water by removing harmful contaminants such as bacteria, viruses, chemicals, and pollutants. This process helps make the water safe for consumption by reducing the risk of waterborne diseases and ensuring that it meets regulatory standards for cleanliness and purity.
