In early March, the Federation of Canadian Municipalities asked Canadian towns and cities to phase out the sale and purchase of bottled water on municipal property. The anti-bottle resolution passed by the federation board of directors carried no legal weight, but encouraged municipalities to speak out against bottled water and avoid distributing it whenever possible.
The movement to phase out the sale and purchase of bottled water on government property has been gaining momentum in Canada and the United States for both environmental and budgetary reasons. However, in Canada the movement is extending to educational facilities such as the Hamilton-Wentworth District’s 98 elementary schools. Last week, the school board trustees voted to remove bottled water from school property by September 2009. Students will still be able to buy soft drinks and fruit juice in plastic bottles.
I agree that government departments should not purchase bottled water (or water cooler water) for their employees at tax-payer expense. Most government employees have access to a staff room with kitchen type facilities. Clean, sustainable, tax-payer funded tap water flows there, and it is safe and healthy for government employees and their clients to drink. Further, purchasing bottled water to sell to employees from vending machines encourages waste and the perception that municipal water is not safe.
Why is Banning Bottled Water in Schools Different?
Banning the sale of bottled water on school property is a different matter. Students may not have easy access to water fountains on school property at all times and they may not always be carrying a bottle with which to make the water portable. As a result many students may choose to buy soft drinks and sweetened fruit juices not banned from school property putting them at risk of becoming overweight -- before they may have chosen bottled water.
Overweight and obesity are health problems that affect a large number of people in the U.S. and other western countries – particularly children. To reduce body weight a person must decrease the amount of calories he or she consumes while maintaining or increasing physical activity. In the U.S., the National Center for Chronic Disease Prevention and Health Promotion says that one of the healthiest ways to reduce caloric intake is to decrease added sugars which provide calories but almost no essential nutrients.
One of the easiest ways to reduce added sugars is to reduce the amount of sugar sweetened beverages (SSBs) one consumes. A large proportion of added sugar in the American diet comes from SSBs. After examining nationally representative data between 1994-1996, researchers found that about 40% of added sugar in the average American’s diet came from non-diet soft drinks and sweetened fruit juice.
In America, the consumption of SSBs begins early. In 2002, 44% of toddlers, 19-24 months of age, had consumed either sweetened fruit juices or soft drinks at least once a day. Studies show that intake increases as children grow older, with the most dramatic rise occurring when children are around eight years old – in elementary school.
What Should be Done Before Bottled Water Can be Phased Out?
Banning bottled water from school property but continuing to sell SSBs (which are also sold in plastic bottles) is not a panacea for our environmental problems. And, although well intentioned it may have unintended consequences for our children’s health. But perhaps with integrated interventions, banning bottled water from school property might be an appropriate step to help reduce the number of plastic bottles in our landfills and recycling plants.
We know that interventions can bring about behavioral change in children. German researchers, recently showed that installing extra water fountains in schools, combined with a small number of simple educational modules to promote drinking water can increase water consumption and reduce the risk of children becoming overweight. Further, in the U.S., the Center for Chronic Disease Prevention and Health Promotion cites a number of studies in which participants significantly reduced their intake of SSBs after participating in a variety of interventions.
From my perspective, school based interventions would include 1) spending to increase water fountains on school property to an appropriate child-to-fountain ratio, 2) redesign of water fountains to allow for a reusable bottle to be more easily filled, 3) educational modules for every child in the school system every year addressing the benefits of drinking water (and not drinking SSBs) and 4) providing a reusable bottle for each child to make water from fountains portable. Only then, should we consider banning bottled water from school property.
