New Project to Reduce Bottled Water Consumption at a Local Area Business Krista Schroeder, Ph. D. student Walden University PH 8165 -3 Instructor: Dr. Raymond Thron Winter Quarter, 2009 -2010

Motives for Decreasing Consumption of Bottled Water in our Workplace Ø Waste Associated with Bottled Water Consumption. Ø Plastic Bottles, Landfill Deposits, Fossil Fuels Ø Exposure to Plastics associated with Bottled Water Consumption. Ø Reduced Quality of Bottled Water compared to Local Tap Water. Ø Inferior Regulation of Bottled Water compared to Tap Water. Ø Expense of Bottled Water compared to Tap Water. These Items will be discussed in detail throughout this presentation.

Plastic Bottle Production Issues Americans purchased 8. 8 Billion Gallons of Bottled Water in 2007 (Responsible Purchasing Network, 2009). “Nearly 50 billion new PET (polyethylene terephthalate) plastic bottles were produced in 2005 from virgin rather than recycled materials” (Responsible Purchasing Network, 2009). Making plastic bottles for bottled water uses 2. 7 million tons of plastic each year (Arnold & Larsen, 2006). The production of bottles for U. S. bottled water consumption, “requires more than 17 million barrels of oil annually, enough to fuel more than 1 million U. S. cars for a year” (Arnold & Larsen, 2006).

Plastic Bottle Disposal Issues According to Arnold and Larsen (2006), post disposal incineration of used water bottles “produces toxic byproducts such as chlorine gas and ash containing heavy metals”. A study by the U. S. Government Accountability Office (2009) found that “three-quarters of the water bottles produced in the United States in 2006 were discarded into landfills and not recycled”. When water bottles end up buried in landfills, they can take up to 1, 000 years to biodegrade (Arnold & Larsen, 2006).

Environmental Impact of the Transportation of Bottled Water Unlike tap water, “which is distributed through an energy-efficient infrastructure”, the distribution of bottled water requires the consumption of fossil fuels during transportation by boat, train and truck (Arnold & Larsen, 2006). These transportation costs increase when bottled water is transported internationally. According to Arnold and Larsen (2009), “nearly a quarter of all bottled water crosses national borders to reach consumers”.

DEHP and Plastic Bottles DEHP is an organic compound that is commonly used to make plastic water bottles (U. S. Government Accountability Office , 2007). According to the Agency for Toxic Substances & Disease Registry (2007), human exposure to DEHP can occur through DEHP leaching from manufacturing companies, DEHP presence and leaching from landfills and handling DEHP containing products. DEHP is an expected human carcinogen (Agency for Toxic Substances & Disease Registry, 2007). According to the Government Accountability Office (2007), the “FDA deferred action on DEHP in a final rule published in 1996, and has yet to either adopt a standard or publish a reason for not doing so, even though FDA's statutory deadline for acting on DEHP was more than 15 years ago”.

Xenoestrogens and Plastic Bottles A study performed by Wagner and Oehlmann (2009), showed that 60% of their tested bottled water samples were contaminated with xenoestrogens. The authors determined that the xenoestrogen contamination “partly originated from compounds leaching from the plastic packaging material” (Wagner & Oehlmann, 2009). According to an article by Wozniak and Murias (2008), xenoestrogens disrupt normal endocrine activities because they “can mimic the activity of endogenous estrogens, antagonize their interaction with estrogen receptors or disrupt the synthesis, metabolism and functions of endogenous female hormones”.

Water Quality Differences Tap Water Bottled Water Under EPA regulations, municipal water companies must “annually provide consumer confidence reports that summarize local drinking water quality information about the water's sources, detected contaminants, and compliance with national primary drinking water regulations” (U. S. Government Accountability Office, 2009). Under FDA regulations, as opposed to the EPA regulations, bottled water companies do not have to provide information on water quality (U. S. Government Accountability Office, 2009). Additionally, the FDA does not have the “authority to require bottlers to use certified laboratories for water quality tests or to report test results, even if violations of the standards are found” (U. S. Government Accountability Office, 2009).

Different Regulations in Regards to Water Testing Source Regulation Confirmed E. Coli & Fecal Coliform Banned? Must Report Violations to the State and Federal Government? Must Test for Must Use Cryptosporidium, Certified Giardia, Viruses? Labs for Testing? Bottled Water Regulated by the FDA (Food and Drug Administration). NO NO Tap Water Regulated by the EPA (Environmental Protection Agency) and State and Local Governments. YES YES This table was produced using data from the Earth Policy Institute (2009).

Expense Bottled water is much more expensive than Tap water. For example, “in California average tap water costs about $1. 60 per thousand gallons (about one tenth of a cent per gallon), while it has been reported that average bottled water costs about $0. 90 per gallon -- a 560 fold difference” (Natural Resource Defense Counsel, 1999). In our company of 5, 000 people, if we consume on average 0. 2 gallons of bottled water per day person at 0. 90 per gallon, this equates to $900 a day or $234 thousand a year (assuming 260 workdays per year). However, if everyone at corporate center switched to drinking tap water the yearly cost would be reduced to $418 (assuming at 560 fold cost savings).

Path Forward Currently our company has a program that supplies bottled water to all employees working at the Corporate Center. In order to reduce bottled water consumption, this program will be terminated. Additionally, the company requests that employees that currently consume bottled water switch to tap water based on all the bottled water concerns sited throughout this presentation. To assist with the transition to tap water the company will be upgrading the Corporate Center water fountains and supplying one reusable water container to all employees.
