What’s in the Water?

There is a high likelihood that at some point in your life, you have used a product containing fluoride. Many of us have memories of fluoride treatments at the dentist’s office—either in the form of a goopy gel oozing out of ill-fitting trays or as a liquid rinse. Even as adults, most people brush their teeth twice a day with toothpaste containing fluoride; all in the interest of keeping their teeth in tip-top shape.

But, did you know that there is a good chance that fluoride is also present in your tap water?

Almost all water has naturally-occurring fluoride. Fluoride is a mineral—like Vitamin D or calcium—that is released from rocks into our air, soil and water; however, depending on the source of the water, fluoride is not always present in concentrations that would be optimal for preventing tooth decay. It is also possible for levels of fluoride to be too high, which is why water providers test  fluoride levels in tap water, allowing them to make adjustments based on current levels.

Fluoride research began in 1901, in Colorado Springs. Initial research was conducted by dental school graduate Fredrick McKay, and in 1909, he was joined by dental researcher, Dr. G.V. Black. Upon arriving in Colorado Springs, McKay noticed that Colorado Springs natives had brown-stained teeth. Having never seen this type of tooth stain before, McKay asked Black to join him so that together, they could determine the source of “Colorado Brown Stain.”

What they discovered was a connection between fluoride in water and dental health. In Colorado Springs, the cause of stained teeth in locals turned out to be dental fluorosis, a cosmetic result of excessive fluoride consumption due to high levels of fluoride in the local water.

According to WebMD, dental fluorosis is caused by overexposure to fluoride—sources include water, toothpaste, mouthwash, etc.—during the first eight years of life, when permanent teeth are being formed. Discoloration can range from lacy white markings to yellow or brown stains and may include surface irregularities, including severe pitting. McKay and Black determined that the high levels of fluoride not only caused the staining, but also provided an unusually high resistance to tooth decay.

In 1931, the first fluoride studies were conducted by Dr. H. Trendley Dean. Based on previous research done in the field, he hypothesized that it was possible to have fluoride levels in water that were low enough to be safe for consumption and avoid dental fluorosis, yet high enough to help prevent tooth decay.

In 1945, his hypothesis was put to the test in Grand Rapids, Michigan; the first city in the world to fluoridate its drinking water. Over the course of 15 years, 30,000 school children were monitored for tooth decay. After 11 years, the caries rate (the rate of tooth decay) was down 60 percent. The study results indicated that tooth decay could be preventable.

running-waterDean’s study spurred a national movement to add fluoride to community water systems and more than 70 years later, the majority of the U.S. population is receiving fluoridated water. According to the Center for Disease Control and Prevention (CDC), in 2014, 66.3 percent of the total U.S. population and 74.4 percent of the population receiving water from a community water system were receiving fluoridated water. 74 percent of Colorado residents are receiving fluoridated water, falling in line with the rest of the country.

Many people receive fluoridated water, but wonder if it’s safe to consume. Everyone has the right to know what they are ingesting and how it will impact their health—check on the fluoridation status of the water that you are receiving at My Water’s Fluoride. Learn about  other contaminants that may naturally occur in your water, or additives like fluoride, and how your water provider addresses them by finding your local Consumer Confidence Report on the Colorado Water Quality Control Division’s website here.

Some people are opposed to the addition of fluoride to public drinking water. Opponents of fluoride in drinking water are troubled by the Food and Drug Administration’s (FDA) classification of fluoride as a drug for safety testing purposes. They see the addition of fluoride to water as being for the sole purpose of preventing tooth decay, as opposed to improving water quality, making it a medical treatment that is being imposed on them without consent.Another concern includes the inability of an individual consumer to regulate their fluoride dosage. Opponents worry that someone who drinks more water than someone else may receive a higher dosage of fluoride. In this vein, the dosage in a single glass is the same across the board, regardless of the needs of the person ingesting fluoride.

In 2013, Portland, Oregon voters rejected a ballot proposal to add fluoride to their drinking water, making it the largest U.S. city without fluoride in their water, or plans to add it. Opponents of the measure echo the belief that fluoride as a chemical will ruin the city’s pristine water supply, and that adding fluoride violates an individual’s right to consent to medication. From a USA Today article:

“I don’t want chemicals in my water,” Sarah Lazzaro said after voting Tuesday. “I know that there are really no known health risks with it, but there’s a lot of things we find out later in life really do have health risks.”

During the summer of 2015, both Snowmass, Colorado and Denver Water debated the practice of adding fluoride to their public water systems. Initially, the Snowmass Water and Sanitation District decided to discontinue adding fluoride to their water; however, in October 2015, under public pressure, the board reversed their decision, and will not discontinue the procedure. Denver Water also found themselves at the center of the fluoride debate, and while they have reduced the dosage of fluoride, per the recommendation of the U.S. Public Health Service, they too, continue to add fluoride to the water they provide. Many who disagree with fluoride being added to drinking water stand firm in their position, keeping the conversation flowing between them and those who view it as beneficial.

The U.S. Public Health Service recommends a fluoride concentration of 0.7 mg/L, or 0.7 parts per million (ppm), to maintain the benefits of reducing the risk of tooth decay, while also decreasing the possibility of dental fluorosis. The U.S. Environmental Protection Association regulates fluoride contamination in drinking water with an enforceable Maximum Contaminant Level (MCL) of 4 mg/L, or 4 ppm and an unenforceable secondary standard set at 2 mg/L. Other agencies including the CDC, the American Academy of Pediatrics (AAP), the American Dental Association (ADA), the American Public Health Association (APHA), the World Health Organization (WHO) and other major health organizations in the United States, believe that community water fluoridation, in recommended low quantities, is safe.

Having clean, safe, drinking water is important to the health of individuals and the environment. Knowing what is in your water and how policy maker decisions can affect public health is the first step in making decisions that will have a positive impact on your personal well-being.

Water Challenges for Young Western Farmers

When you hear the word “farmer,” what is the first thing that comes to mind? Most people have a preconceived notion of what farming looks like, as well as what is involved in the actual practice of farming. While the average age of an American farmer is 58, and farmers over the age of 65 outnumber farmers under 35 by a ratio of six-to-one, the next generation of farmers is emerging across the country. Their work is yielding joys and challenges previously not experienced, as young farmers face a future impacted by drought, climate change and increasing municipal demands on water supplies.

This recent crop of innovative young farmers is featured in the newly released short film Conservation Generation, presented by the National Young Farmers Coalition (NYFC), an organization that “represents, mobilizes, and engages young farmers to ensure their success.” The four young farmers featured in Conservation Generation are working hard to run successful farms in the arid West, with two of them farming on Colorado’s Western Slope; Harrison Topp of Topp Fruit in Paonia, and Tyler Hoyt of Green Table Farms in Mancos.

One of the major struggles for farmers in this part of the country is the ever-increasing scarcity of water. This challenge requires that farmers find innovative solutions to the water shortages that they face. In blog posts they’ve written for the National Young Farmers Coalition to accompany the video, Topp and Hoyt each explain that picking the right land to farm was a crucial component for ensuring that their farms will have access to water.

“Water needs to be at the forefront of how we operate because it will (hopefully) help to keep us in business,” Hoyt says in the film. Both farms are located close to the headwaters of the rivers and streams that Hoyt and Topp draw from, ensuring that the water used for irrigating their crops is less likely to be contaminated by pollutants than it might be if they were further downstream.

The farmers employ irrigation techniques that allow them to conserve and make the best use of the water that they are able to use. For Topp, this involved improving the method for transferring the water they are allowed to take from the Fire Mountain Canal to the orchard.

“We had a beautiful (but totally inefficient) network of hand-dug ditches that delivered water across the orchard,” says Topp, in one of his blog posts about the original irrigation system on his farm. “Stones, dirt, shovels, tarps and metal fragments were used to get the water to flow where I wanted. It could take hours to get the right amount of water kind of close to where I needed it to go.”

According the U.S. Environmental Protection Agency, as much as 50 percent of water used for irrigation is wasted due to evaporation, wind, or runoff caused by inefficient irrigation methods and systems. While Topp notes that their new method of irrigation—use of a gated pipe—is not as efficient as he would like, it works well for the orchard, and is an improvement.

On Green Table Farms, Hoyt employs a host of methods that allow him to make the most of the water that he has access to. “I grow a lot of indigenous crops; those varieties that have been grown out here under dry land conditions for a very long time,” Hoyt explains in the film. “[The use of] drip tape is definitely a huge way that we manage our water so that in those years when we get very little, we can still irrigate.”

The face of farming in the United States is changing. With those changes come new challenges, some of which are the result of  climate change and increasing water scarcity. Young farmers across the country, like those featured in Conservation Generation are optimistic that by working hard, and applying their own creative ingenuity, they can find ways to overcome the issue of water scarcity and keep agriculture alive and growing in the arid West.

Additional information about the Conservation Generation can be found in NYFC’s report, Conservation Generation: How Young Farmers and Ranchers Are Essential to Tackling Water Scarcity in the Arid West; a survey of 379 young farmers in the arid West and recommendations on how their work can best be supported.

2017 New Year’s Resolution: Invest in Water Quality to Invest in Your Health

It’s that time of year again—time for making New Year’s resolutions. Many of our resolutions will involve personal health or investment goals for 2017. But are you tired of setting weight-loss or money-saving goals? This year, consider investing in water quality as an investment in your own and your family’s health.

Safe and readily available water is one of the most vital components of our health. We have already seen our watersheds affected by major floods and wildfires. As climate change occurs and population doubles in Colorado, our waters will come under more pressures. We need to create resilient watersheds that can handle these pressures to avoid catastrophic conditions in our water. Watersheds that support strong ecosystems will produce the ecological diversity integral to our food chain and plants and minerals that someday could be used in medicines.

Water also is fundamental to our mental health. Studies show humans’ mental health improves with time near water. Set a goal this year to stroll on a path along a stream once a week and reflect on the soothing sound of the water. Imagine being connected to the source of our water and where it goes when we flush our toilets, wash our cars and water our lawns. Being connected in this way reminds us about the importance of investing in water, the essence of our existence.

Most of us understand that water is a basic necessity in our lives. We all want clean and safe water in our taps and in our streams. And yet, do any of us know how much we are paying our local utilities to ensure protection of this resource? When was the last time we readily and voluntarily agreed to increase our investment? None of us like increasing costs, but an increase in our water utility bill is not just a rate increase. It’s a proactive step to invest in our health. We know our water and wastewater infrastructure is aging. Reports show if we don’t start investing now, by 2040 we will have a $152 billion funding gap for needed infrastructure. This year, consider changing that trend and instead stand behind your utility when it proposes a rate increase.

The challenges that utilities face are immense. Utilities can use increased funds to protect our water at its source, replace aging pipes that deliver water to our homes, and upgrade treatment processes to keep up with current science and technology. Imagine if we all took the money we might routinely spend on two sugary beverages a month and instead invested it in water quality. Imagine if businesses that provide charitable donations or hold fundraisers directed that money to water quality. Imagine the possible replacement of lead-laden pipes and the removal of arsenic and other metals. Imagine algae-free streams and rivers available for swimming and fishing. Check in with your local utility or watershed group to see what work needs to be done in your area. Maybe it’s aging pipes, stream bank restoration or an upgrade to a water treatment plant. Then ask how you can get involved.

As you are reflecting on the past year and embarking on another, ask yourself how much it is worth to turn on your tap at home and know the water will be good for your health. This New Year, how much are you willing to invest in your and your family’s health?

Successful Implementation of Colorado’s Water Plan Requires a Data-Driven Mindset

nicolebc2014webNicole Seltzer, the Colorado Foundation for Water Education’s former executive director moved on last week from her position at CFWE to pursue a personal goal of spending more time enjoying Colorado’s mountains. While working at CFWE, Nicole led the organization through a period of growth by doubling staffing levels, diversifying programs, and increasing the budget by over 60 percent. She has become a strong voice and leader for Colorado’s water community. Although she hasn’t gone far to her new home on the West Slope, we’ll miss Nicole at CFWE. Before leaving, Nicole wrote a number of letters to impart some of her wisdom—read some thoughts from the Colorado Water Conservation Board’s December newsletter, on data-driven water education:

In the 15 years that I’ve conducted water education and outreach in Colorado, I’ve learned that the conversation never stops at water. To have an intelligent conversation about water, I also need to understand western history, ecology, forest health, economic development, recreation management and so much more. There are thousands of public policy issues you can connect back to water.

I think this is why I’ve so appreciated my time as the executive director of the Colorado Foundation for Water Education. As someone who enjoys making connections between people and issues, CFWE is the perfect home to explore meaningful topics through a lens of water. Even seemingly disconnected topics like leadership skills or behavior change are absolutely relevant to water conversations.

I’ve recently had the pleasure to work alongside Colorado Water Conservation Board staff to discuss implementation of the education and outreach strategies in Colorado’s Water Plan. The conversation initially focused on the actions outlined in Chapter 9.5 to examine current gaps in water education, and use that information to support dedicated funding for outreach activities statewide. This is sorely needed, and will be a great starting point.

The plan contains much to be proud of, from goals around municipal water conservation to integration with land use planning to stream health to funding mechanisms. While they are wide ranging and diverse, I believe there is a common thread that connects them. None, in my opinion, are achievable without dedicated outreach and engagement strategies that have clear goals and metrics to measure success.

Good water education increases awareness of the severity and complexity of water issues, creating concern and the desire to get involved. Good water education broadens perspectives and helps us walk a mile in another’s shoes, developing compassion for other viewpoints and a willingness to explore rather than disengage in the midst of disagreement. Good water education widens the number of people invested in our water and river systems, producing collaborative solutions that meet multiple needs. Good water education promotes uncommon alliances by connecting people around common interests instead of dividing them with their differences.

How, as the Colorado water community, can we support the CWCB as it seeks to implement these goals we’ve adopted together? From my vantage point, I see one fundamental priority that would put us on the right path. Adopting a data-driven mindset about water education would immediately increase the amount, quality and effectiveness of these programs, which is a backbone of water plan implementation.

Our profession is driven by and beholden to numbers: gallons per capita per day, milligrams per liter, pounds per square inch. But we rarely apply the same logic to outreach and education programs, or if we do, it is through proxies like the number of people at an event or how many factsheets were handed out. What if we began to hold ourselves to a higher standard? Instead of collecting no or loosely relevant data, we clearly identified the outcomes we sought, and developed robust mechanisms to track them?

Two actions would help us move in the right direction, both of which are currently being considered by CWCB as they work to prioritize implementation of water plan goals.

First, the development and funding of a centralized, regularly repeated statewide survey of public knowledge, attitudes and values. We need a baseline as a state against which we can measure the success of education and outreach programs. There are numerous surveys that have been completed in the last 5 years, but most seek to answer a narrow set of questions, are limited to a certain geography and are never repeated. Just like we track the water quality in a stream before, during and after a project, we should measure shifts in public opinion and knowledge on water. To be truly useful, this undertaking must be a statewide partnership that is developed, funded and used by a wide variety of entities. And it must be repeated on a regular basis to have lasting value.

Second, we must create a set of consistent metrics that water education professionals could opt to use to gauge their effectiveness. You cannot understand that which you do not measure. A standardized set of metrics that can be used by all outreach and education programs in Colorado will help us set collective goals, hold ourselves accountable to meeting them, and create an ethic of outcomes-based success that does not currently exist.

CFWE has already taken several strategic steps that align well with water plan goals. These include fostering our Water Educator Network to increase the amount, quality and effectiveness of water education programs in Colorado, developing our Water Fluency program which empowers community leaders who are not currently engaged in water to critically think about these issues, and focusing our print and online content to examine a wider array of public policy issues through a lens of water. We also collect a large amount of both quantitative and qualitative data on the impact of our work, and use that to regularly reflect and improve upon our programs.

As Colorado’s leader in water education, CFWE is excited to be CWCB’s partner in the planning and execution of these important and far-reaching goals. Though I will step down as executive director in December, CFWE will remain committed to its core values of maintaining an unbiased, objective viewpoint that encompasses diverse perspectives on water resource issues and producing high‐quality educational tools and experiences. We will use our expertise to help lead the way in implementing Colorado’s outreach and education goals, and foster the conversations necessary to get there. And of course, we’ll do all of this while also having a good time.

Valuing Water

When we don’t witness water treatment plants in action, infrastructure being maintained and the sale and trade of water rights, it can be easy to forget that the cost of water involves more than our personal usage wrapped up neatly in a monthly bill. In reality, what we pay each month may not appropriately reflect the true cost of water. As Colorado’s population grows, the demand on already limited water resources will rise and the cost of water will likely increase—with higher totals often transferred to your water bill.

Beginning Jan. 1, water rates will increase in some towns and cities around the state ̶ including Aurora, Colorado Springs, Denver and Louisville. Depending on where you live, and how your water bill is broken down, utilities may use those monies for standard water treatment and delivery costs, conservation and education programming, infrastructure construction and maintenance, upgraded treatment systems, or even securing new water supplies. Read more about why Denver Water bills are increasing in this new post on Mile High Water Talk.

“As water becomes increasingly scarce, prices are going to go up,” says Charles Howe  professor emeritus in the Department of Economics, Institute of Behavioral Science at the University of Colorado, Boulder. Howe joined KGNU’s Maeve Conran for an interview to discuss economics and the value of water on Connecting the Drops, our collaborative radio series between CFWE and Rocky Mountain Community Radio stations.

“Any new [water] use is going to face increasing prices,” Howe says. This is seen in the trade of water rights and reflected in users’ water rates. For water providers and town councils setting rates, the need to stretch scarce water supplies among multiple users and valuable uses increases the necessity of efficient water use and higher levels of conservation. Rates can be an effective tool for encouraging water conservation.

“It is very well established that users are sensitive to water prices. We know that as prices go up, users of every class do reduce use,” Howe says. “They gauge their usage of water so that they are not dumping costly water onto low value uses.”

How can rates encourage conservation? Conservation water rates send a price signal to customers to conserve—a variety of rate structures can accomplish this or can be mixed and combined. Many municipalities including Aurora, Colorado Springs, Denver, Durango, Fort Collins, Grand Junction, Steamboat Springs, Vail, Walsenburg and Westminster use some form of tiered or increasing rate structure. In a tiered or increasing rate structure system, cost to the user increases in steps and is dependent on the amount of water used. Lower pricing steps exist because low-income customers and small households cannot afford to pay high prices for essential water usage. As use increases, price increases per thousand gallons of water used. Very high volume users—whether households, industry, or businesses—are charged the highest prices because their demand determines the peak capacity of the system.

In Denver, the pricing structure moved from a four tier to a three tier system in which anything beyond “essential” use sees a significant increase in price. This, Howe notes, is a mechanism for encouraging conservation. Although prices are on the rise, Howe is of the mindset that municipalities are not charging enough to urban users. An increase of $25-30 per month would better reflect the value of the raw water that is being treated and distributed to the average urban customer, he says. Howe suggests that attention should also be focused on large-volume users in the commercial sector. They can be motivated to conserve water through increased pricing, therefore placing an appropriate value on the amount of water that they are actually using, he says.
