The administrative board for Denver Water voted Wednesday to continue its policy of adding artificial fluoride compounds to the city’s public water supply. The decision comes after the board held a special session last month in response to a 5 year campaign by activists from We Are Change seeking an end to the mass fluoridation of public water supplies.

The forum featured a panel of 6 experts, 3 per side, with the pro-fluoridation side touting largely outdated resources which are often cited on this issue. The opposition provided detailed and specific counterpoints to the same resources from the pro-fluoridation panel, including the Harvard study showing fluoridation linked to lower IQ in children. The evidence and video of the debate can be reviewed on Page 2 as the panel’s presentations were released to the public.

Despite this evidence, the Denver Water board voted to continue the policy of adding sodium fluorosilicate or fluorosilicic acid to the water supply when the raw source water does not meet the target range of 0.7 to 1.2 mg/L, levels recommended by the US Department of Health and Human Services and the US Environmental Protection Agency. These two chemicals are the most common artificial fluoride additives in America and are usually raw waste products from the mining industry, containing toxic chemicals and heavy metals, in addition to fluoride’s toxicity.

The decision was seemingly unpopular as the board received over 1000 public comments following the July forum, most of them in opposition.

The discussion of fluoride added to public water supplies is confusing to some as fluoride compounds are found naturally in many areas as a result of environmental cycles. Denver Water’s raw sources have varied levels of naturally occurring fluoride which changes with mountain snow runoff and other seasonal factors.

Regardless of the natural fluoride content, the harmful effects from the toxic waste additives was the central issue in the debate yet was basically ignored by the board, at least as represented by public statements.

After reviewing the presentations, the extensive research on this issue, and the advice of public health and medical professionals in Colorado, the board announced there would be no change in its water fluoridation policy.

The resolution the board adopted at its meeting stated: “Nothing we heard through the presentations or learned in research would justify ignoring the advice of the public health agencies and medical organizations or deviating from the thoroughly researched and documented recommendation of the U.S. Public Health Service.”

One board member added further reasoning to justify the decision claiming that they could not provide consistency and customers would receive different qualities of water.

Commissioners also noted that if Denver Water stopped managing fluoride levels, our customers would still be drinking fluoridated water.

“But the levels would vary significantly, creating an imbalance throughout our service area,” Denver Water Commissioner Penfield Tate said. “Community water fluoridation provides dental health benefits across all socioeconomic communities in a predictable and uniform manner.”

This claim is false for two major reasons. As proven in a July article, the system is already providing an inconsistent product based on Denver Water’s policy of adding fluoride derivatives because of the water system’s structure, which they claim provides about 20 percent artificially fluoridated water. The 20 percent claim has been presented in response to the opposition to toxic chemicals as evidence that Denver Water does not add much fluoride to the water supply.

The second lie is that the system could actually provide a more uniform product without adding fluoride derivatives because of its unique construction which can send water from anywhere to any of the system’s three treatment plants.

Denver Water’s 2013 Treated Water Quality Report

Denver Water’s distribution system is completely integrated. This means that we can distribute water from any of our three potable treatment plants to anywhere in our system. Water is usually routed based on demand. Foothills Treatment Plant is our largest gravity fed potable water plant. It is often in service and serves much of the system.

However, we can blend water from Foothills with Moffat or Marston or blend the water from any two potable treatment plants and send it anywhere in our
system. This complete redundancy is rather unique compared to other distribution systems in the United States.


WTF News spoke privately with Commissioner Tate after the July forum on this specific issue, as well as the difference between naturally occurring fluoride and the artificial chemicals

During this conversation, Commissioner Tate noted that the water system “would be providing an inconsistent product” by not adding chemicals, hinting that this would be the main consideration of the board. In response, information was presented from the WTF News July article that Denver Water’s system is already providing an inconsistent product based on these facts.

When further questioned on these facts and also that himself and the other board members had just listened to an hour of presentations pointing to the evidence of harm caused by these added fluoride compounds, Commissioner Tate insisted he was late for a meeting and got in his car.

Prior to the forum in July, WTF News reported that one of the treatment plants always received significant added quantities of artificial fluoride, while the toxic compounds were added at the other two plants for about half of the calendar year.

Denver Water used to document the amount of fluoride derivatives added to the water at different testing sites in annual Treated Water Quality Reports, however those more detailed reports stopped being publicly available after the 2013 report.

The charts below, from the 2011 and 2013 reports, are showing the significant differences at the 3 water treatment sites.

The Foothills location, the largest in the system, shows high levels of natural fluoride but is supplemented for about 5 months of the year. The other two plants are significantly higher, with Marston receiving artificial fluoride in at least 8 months, and all year at Moffatt treatment plant. The natural fluoride levels at the Moffatt plant average about 20 percent of the minimum target range meaning the other 80 percent is made up by adding chemicals.
