(WXYZ) - There are so many types of bottled water available, it's hard to figure out what's best for you.
Are there different kinds?
7 Action News asked the experts at Michigan-based Absopure to find out how bottled water differs.
Frank Zolenski, Absopure's marketing director, says there are two main types; spring water and purified water.
Spring water comes from a natural source and may contain minerals.
"Purified drinking water is water that's gone through a process of either reverse osmosis, deionization or distillation to purify whatever the source water was into a cleaner, crisper water that's clear of any minerals or other things that may have been in it," Zolenski said.
He also said there isn't much of a difference between the two in terms of health benefits, though spring water could be considered the more natural option.
Zolenski believes the biggest difference is the taste.
Where does it come from?
Bottled water labels are the best indicator of how the water is treated and processed.
Most labels will also include the source of the water, but beware of terms like "glacier water" and "mountain water." The Environmental Protection Agency says those terms are not regulated standards and may not mean the water is from a pristine area.
Does it expire?
Most bottled water comes with a "use-by" or "sell-by" date, but according to the Food and Drug Administration (FDA), bottled water does not expire.
Many companies, like Absopure, use the "sell-by" dates to track when the water was bottled.
According to the International Bottled Water Association, dates placed on bottles may also be used by companies to manage stock rotation at distribution and retail levels.
Should I store it at a certain temperature?
Some people have also worried about drinking bottled water that has been left in a hot car.
Most bottled water companies do not recommend drinking water that has been stored in extreme temperatures.
The FDA has reviewed the safety of bottled water exposed to higher temperatures and found it's possible for the materials from the plastic to enter the water, but the amounts were so small, the FDA did not consider it a public safety concern.
