A number of communities (campuses, towns, cities, etc.) around the world have proposed and enacted plastic water bottle bans in some form.

In 2013 the small town of Concord, Massachusetts (population approximately 19,000) became the first town or city in the United States to ban the sale of single-serving Polyethylene
terephthalate (PET) bottles less than or equal to 1 liter (34 ounces) containing water which is non-sparkling and non-flavored (in other words, plain water)[1]. The sale of water in bottles of any size made of other types of plastic or other materials, as well as PET bottles of flavored or sparkling water, soda, tea, juices, and other non-plain water beverages, regardless of size, is allowed[2].

Concord citizens supporting this action stated various reasons including: concerns of plastic garbage and litter, use of fossil fuels in the production of plastic, product transportation
emissions, damage to water-providing aquifers, and beliefs that businesses shouldn’t profit on the sale of a free resource.

Since enactment of Concord’s ban, a handful of other communities in the United States have enacted single-serving water bottle bans, the largest being the city of San Francisco (population approximately 885,000) who banned the sale of single-serving water bottles on city property in 2014[3]. Just recently, the San Fran Francisco Airport decided to comply with its city’s law and banned the sale of single-serving water bottles, making it the first airport to do so[4].

Not everyone is in favor of these bans, nor does everyone think that these bans will have any impact on the issues they are trying to address. Opponents include the International Bottled Water Association (IBWA) who, after the San Francisco ban, stated that there are unintended consequences to these bans as they may lead to “more packaging, more additives (e.g., sugar, caffeine), and greater environmental impacts than bottled water[5].” Additionally, as we have seen in recent world news, in some areas (e.g. unavailability/ inaccessibility of fresh water) and under some circumstances (e.g. natural disasters, compromises in water delivery) bottled water is a necessary and critical resource.

1. Model the impacts of a ban on the sale of single-serving water bottles in a town or city. Use your model to discuss the impacts of the bans in the Town of Concord and the City of San
a. Identify the possible impacts (positive and negative) of a ban on the sale of singleserving water bottles within a town or city.
b. What information and data do you need to model and measure these impacts? How would you collect this information and these data? (Note: You do not need to actually collect information and data, but need to identify what you need and how you might obtain it.)
c. Develop a model or set of models to measure water bottle ban impacts.
d. Discuss the application of your model to Concord and San Francisco.

2. Address the impacts of a ban on the sale of single-serving water bottles within an airport. How are the impacts similar to and different from a ban in a town or city? How would your initial model for a town or city change, if at all, to model bottle ban impacts within an airport?

3. Discuss and recommend possible changes to Concord’s water bottle ban, or other related community measures, that would enhance beneficial impacts and reduce adverse impacts. Use your suggested changes to adjust your impact model. Address whether or not your new model is generalizable to larger communities (e.g. large cities, regions, states, countries).

4. Write a one-page article for your local newspaper reporting your findings and recommendations.

Your submission should consist of:

  • One-page Summary Sheet.
  • Table of Contents.
  • One-page Article.
  • Your solution of no more than 20 pages, for a maximum of 23 pages with your summary,table of contents, and article.

Note: Reference List and any appendices do not count toward the page limit and should appear after your completed solution.
