Water is our most valuable shared resource and together we can keep it
that way for generations to come.
Bottled Water vs. Mountain Water

According to a scientific study by the National Resources Defense Council, bottled water sold in the United States is not necessarily cleaner or safer than most tap water.

Out of more than 1,000 bottles representing 103 brands of bottled water tested, the study found that about one-third contained some levels of contamination including synthetic organic chemicals, bacteria, and arsenic.

The NRDC study attributed the findings to FDA rules that exempt waters packaged and sold within the same state (60-70 percent of all bottled water sold in the U.S.) from federal regulation. Not all states, they found, bother to regulate these bottled waters either and less than half of U.S. states require carbonated water to meet the same standards as noncarbonated bottled water.

In addition, bottled waters that are covered by the FDAs rules are subject to less rigorous testing and purity standards than municipal tap water. Bottled water is tested less frequently for chemical contaminants and bacteria, is not required to be disinfected or tested for parasites like cryptosporidium and giardia, and is sometimes permitted to contain small amounts of contamination by E. coli or fecal coliform.

By contrast, Mountain Water Company rigorously tests for the presence of metals, pesticides, inorganic and organic chemicals, and microbiological organisms every year. We follow the strict regulations established by the United States Environmental Protection Agency (USEPA) and the Montana Department of Environmental Quality (DEQ) to ensure that your tap water is clean and safe to drink.
