Bottled Water Students Promoting Environmental Awareness and Responsibility February 16, 2009
The Bottled Water Craze Is Upon Us! Why do people ♥ bottled water?
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
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
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
Economic Impact US bottled water consumption (2005) – 30 gal / person / year – $15 billion / year – Prices: $1 to $180 per gallon
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
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
HDPE 1,755,000 tons sold in 2006 About 73% is not recycled
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
