Is My Water Safe to Drink?

What does “Safe” Drinking Water Mean?

Drinking water, which is also known as potable water, is the water used for drinking, bathing and making food. The definition of “safe" drinking water is not universally defined. In California, a definition specific to a few codes is that “Safe drinking water” means water that meets all primary and secondary drinking water standards. Drinking water standards are set based on potential health impacts and also take into account the cost to meet the drinking water standard. Also, the U.S. Environmental Protection Agency (EPA) defines drinking water as safe when humans can drink it with low risk of immediate or long-term harm to your health. Although there may be health risks associated with certain contaminants found in drinking water not all contaminants are necessarily harmful.
