Project 7 Adjusts Water Treatment Process

On July 31, 2014, the Project 7 Water Authority (P7) stopped supplementing fluoride in treated drinking water. The City of Montrose distributes P7 treated drinking water within its water district and wishes to inform customers of this change in the water treatment process.

On August 25, 2005, Hurricane Katrina destroyed the only dry fluoride production plant in the US, and the plant discontinued dry fluoride production. P7 continued purchasing dry fluoride from this US source until remaining supplies were depleted. With existing P7 dry fluoride supplies dwindling, Plant Manager Adam Turner investigated alternative product sources and discovered that only Chinese-manufactured dry fluoride was available. Concerned with the quality control practices of chemical manufacturers in China, the P7 Board of Directors unanimously approved the discontinuation of P7 water fluoridation when the existing supply of US-sourced dry fluoride product was exhausted.

The decision to end fluoridation of treated drinking water was based solely on the inability to obtain dry fluoride from a reliable source and in no way challenges consumer opinions regarding dental health benefits related to fluoridation.

Fluoride exists naturally in local raw water sources that supply the P7 water treatment plant. The dry fluoride formerly added to treated drinking water merely supplemented naturally occurring fluoride levels. A variety of products are available to individuals wishing to continue fluoride supplementation. These include certain tooth pastes, mouth wash products, and fluoride rinses. Individuals should consult with their dentists prior to using these, or other products.
