1 Bottled Water Students Promoting Environmental Awareness and Responsibility February 16, 2009

2 The Bottled Water Craze Is Upon Us! Why do people ♥ bottled water?

3 Taste, Color, and Odor Varies based on minerals present Tap water varies greatly by region and season Bottled water flavor can be affected by type of plastic Temperature affects taste – Taste is less noticeable in ice-cold water than warm water

4 Quality and Safety Regulated by FDA and EPA – Specific guidelines for testing and maximum amounts of minerals/contaminants Tap water often has stricter standards than bottled water Taste, odor, and color don’t always indicate if water is healthy or not – Sulfur affects smell and taste but is safe – Some harmful contaminants have no color, taste, or odor

5 What Is Bottled Water, Anyway?

6 Source of Bottled Water 25%-30% of US bottled water are “bottled tap water” – e.g. Dasani, Aquafina Labels must include “from a municipal source” or “from a community water system” if tap water is not further treated – Some simple, ineffectual treatments eliminate the labeling requirement

7 Economic Impact US bottled water consumption (2005) – 30 gal / person / year – $15 billion / year – Prices: $1 to $180 per gallon

8 Environmental Impact Plastic water bottles are made from – PET (polyethylene terephthalate; ) Derived from crude oil – HDPE (high-density polyethylene; ) Milk containers – Polycarbonate (part of ) Nalgene bottles Eyeglasses

9 PET 2,713,000 tons sold in 2006 Less than 1/3 of 1% of total US waste (IBWA; no references) About 76% is not recycled

10

11 HDPE 1,755,000 tons sold in 2006 About 73% is not recycled

12 Sustainability Efforts US: container deposit legislation (“bottle bill”) – About 30% of US population affected (2004 Census) Campaigns – UNICEF’s Tap Project – Think Outside the Bottle – Inside the Bottle
