Q1: There is fluoride in Mountain Valley Spring Water. Tell me about it.

The Mountain Valley spring source has 0.1 milligram per liter (equivalent to one tenth of one part per million) of naturally occurring fluoride in it. It is not added to the water nor modified in any way during the bottling process. This amount of fluoride is far below the amount added by municipalities to tap water which varies between 0.7 to 1.2 mg/L (the variation of concentration depends on the temperature of the water as temperature affects the solubility of the fluoride mineral).

Fluoride in solid state comes in a lot of variations as this naturally abundant mineral combines readily with other minerals. We are not sure what the state of the fluoride mineral was (sodium fluoride, calcium fluoride, etc.) before it dissolved in water and shows up in our spring water as a fluoride ion. After the point the fluoride is dissolved in the water, the fluoride ion is unattached to the other mineral and is undistinguishable from other free fluoride ions.

We are aware there is a lot of continuing controversy about fluoridation of municipal water sources. Mountain Valley Spring Company has protected and bottled this spring source for over 140 years now and has had no reported issues related to fluoride by any of the many generations of loyal consumers.

Q2: What about Bisphenal A (BPA) in water bottles.

There has been a lot of varying information about BPA in the press recently and many consumers are understandably confused. As a result, a lot of people have decided to simply avoid plastic that may potentially contain BPA or even avoid plastic entirely.

The easiest answer first: Mountain Valley has been known for bottling in glass for over 140 years! If you are concerned about BPA or plastic in general, buying Mountain Valley in glass bottles in sizes from 11.2 ounces to 5 gallons is the ultimate way to give yourself peace of mind about your packaging choice.

If you want to avoid BPA but still want the convenience of a plastic bottle, look for bottled water bottles with the recycling #1 on the bottom. It is made from PET plastic and PET plastic does not have the necessary precursor chemicals to create BPA when it is scratched or washed under high temperatures. All small sizes of Mountain Valley Spring Water bottled in plastic are made with PET.

The bottles potentially containing BPA are made with the harder polycarbonate (PC) plastic and are easily identified with the recycling # 7. If you are concerned about BPA, avoid those packages.

Q3: What are those white flakes in my Mountain Valley Water Spring?

Mountain Valley Spring Water has 220 milligrams per liter (or 220 parts per million) of naturally occurring minerals in solution form. The chief mineral found in our water is calcium carbonate at 67 mg/l. Sometimes, when there is a rapid temperature change, the calcium normally in solution form can “precipitate” or turn into solid form. The solid form of calcium is those white flakes you are seeing.

Mountain Valley Spring Water will most often undergo this transformation in the winter as our bottled water is moved from warm warehouses to cold doorsteps for delivery. But it can also occur as a result of moving a cold bottle from the refrigerator and putting it on a warm counter for an extended period of time or by boiling it to make tea or coffee.

The white flakes of calcium are good for you! It is a naturally occurring form of calcium easily absorbed by the body.

Q4: Tell me about the high ph (alkalinity) of Mountain Valley Spring Water.

Ph is a measure of the acidity or alkalinity of a food or beverage with neutral being 7 and acidity below and alkalinity above that measure. Many people believe foods and beverages with high or alkaline ph (over 7) are good for human health. Mountain Valley Spring Water comes out of the ground naturally high in ph at 8.02. The final ph after being bottled drops slightly to an average 7.80 because our bottling process exposes the water to ozone (three molecules of oxygen) for the sake of ensuring purity and the oxygen lowers the ph somewhat.

The ph of our Mountain Valley Sparkling Water is not high. The carbon dioxide added to the water to make the bubbles enjoyed by many substantially lowers the ph to an average of 5.8.

Q5: Gas Shale Concerns

Quite a number of Mountain Valley customers have expressed concern about the recent “Fayetteville Shale” gas drilling activity in the State of Arkansas and the “fracking” accompanying the drilling. As you can see from the map below, the Mountain Valley spring is far removed from the shale gas drilling in Arkansas. In addition, the geology and aquifers of the two areas are quite different and unconnected.

The Ozark Plateau, where the shale drilling is happening, is a “Karst” geology whose prominent feature is limestone with many surface fractures. The Ouachita Mountains where the Mountain Valley spring is located is a granite based geology with local aquifers formed in valleys of the ancient mountain range.

Mountain Valley owns 2,000 acres surrounding the spring to protect it and we have an extensive testing regime to ensure its quality.
