Water Quality

The quality of Mountain Valley Spring Water begins with the natural spring source located 12 miles from Hot Springs National Park, Arkansas. No activities are allowed on the 2,000 acre watershed which has been protected since 1871..

The water flowing from the natural spring is tested daily by our quality control staff, monthly by the Arkansas Department of Health, annually by the National Sanitation Foundation, and periodically by other governmental bodies and private companies using our products. Everything coming into contact with our water during the bottling process, including the stainless steel holding tanks, piping, bottles and caps is carefully tested daily.


While Mountain Valley is being bottled, the water is filtered and ozone is added to ensure there is no biological contamination. Ozone is used because it is quite effective against a wide variety of potential contaminants, but also because it breaks down into oxygen after it is in the bottle. The bottling process is monitored every 10 seconds for pH, conductivity, ozone residual and total dissolved solids. Bacterial tests are taken daily and incubated. Sample cases of product from each production run are put aside and reserved for six months. The records of all in-house and third party testing (governmental agencies or independent companies) are maintained for 10 years.

Additional rigorous oversight and inspections (both surprise and announced) come from the Food and Drug Administration, the Environmental Protection Agency, the U.S. Military, the National Sanitation Foundation (on behalf of the International Bottled Water Association) and the Kosher Union. Mountain Valley Spring Water is also scrutinized carefully by diverse governmental authorities in countries such as Japan, Canada, and the United Arab Emirates.

In addition to the frequent testing described above, our premium spring water undergoes an extensive annual analysis by a laboratory certified by the EPA to analyze drinking water. This analysis, mandated for all companies belonging to the International Bottled Water Association, shows the natural occurring minerals and properties of our water and also tests for 187 potential contaminants.
Despite what some critics of bottled water may say, this required analysis far exceeds the scope of the testing required of municipal tap water systems and the "maximum contaminates" allowed by governmental authorities for bottled water is significantly lower than is allowed in municipal tap water for important things like lead and disinfection byproducts.
