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.

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.
