Potable water is water that's safe for human consumption, containing beneficial minerals like calcium and fluoride. It comes from sources such as rivers, lakes, and groundwater, and undergoes treatment to remove contaminants and pathogens. Regulatory standards ensure its safety, making it essential for drinking and cooking, unlike pure water, which is used in labs and industries.

Potable water contains beneficial minerals while pure water lacks them
Surface Water
Potable water can be sourced from rivers, lakes, and reservoirs
Groundwater
Groundwater is naturally purer than surface water but still requires treatment
Rainwater
Rainwater can be collected and treated to make it potable
Filtration
Potable water is treated through coarse and fine filtration to remove impurities
Chemical Treatment
Chemical coagulation and disinfection are used to remove dissolved substances and harmful microorganisms
Advanced Treatment
Additional treatments like activated carbon filters and membrane technologies can further improve water quality
Potable water should be clear and odorless
Potable water should be free from harmful contaminants and pathogens
Potable water should contain safe levels of minerals that contribute to taste and health benefits
Potable water is essential for maintaining good health
Drinking and Cooking
Potable water is used for drinking and cooking in households and the food industry
Industrial Applications
Pure water is used in industries where the presence of minerals could interfere, while potable water is suitable for regular use
Electricity Conduction
Potable water is a conductor of electricity due to its dissolved minerals, unlike pure water
Regulatory standards, such as the EPA standards, define safe levels for various substances and parameters in potable water
Potable water can be found in municipal water supplies, wells, treated rainwater systems, and protected springs
It is important to ensure the potability of water from sources like public fountains, which should be clearly marked as safe for drinking

fluoride
01
Groundwater vs. Surface Water Purity
Groundwater typically purer due to natural filtration through soil/rock; surface water more susceptible to contaminants.
02
Potable Water Treatment Necessity
Both groundwater and surface water require treatment to remove contaminants and ensure safety for consumption.
