What percentage of bottled water is actually tap water?

In 1999, after a four-year review of the bottled-water industry and its safety standards, NRDC concluded that there is no assurance that bottled water is cleaner or safer than tap. In fact, an estimated 25 percent or more of bottled water is really just tap water in a bottle—sometimes further treated, sometimes not.

Are there standards for bottled water?

Bottled water is regulated at three different levels: federal, state, and trade association.

It also states that bottled water must label the source.

How pure is tap water?

There is also a risk of lead in tap water due to lead being present in the pipes that bring tap water to your home. DC tap water ranges from 200 PPM to 400+ PPM in TDS (total dissolved solids), which measures the concentration of soluble impurities in pure H2O.

Does the FDA approve bottled water?

The Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) are both responsible for the safety of drinking water. EPA regulates public drinking water (tap water), while FDA regulates bottled drinking water.

How purified water is suitable for drinking?

Distillation purifies water by using a heat source to vaporize it. When the water becomes a vapor, it separates the liquid from any contaminants or debris that can appear in surface water or groundwater. The process of distillation is simple. Water has a much lower boiling point than solids and minerals.

Does bottled water have to be FDA approved?
