At our April 2010 Greening Your Library workshop we tested supplying tap water instead of bottled water and guess what, no one said a word. We’re not even sure anyone noticed.
@MHLS our new interim director, Merribeth Advocate (a master at reducing costs), just declared we will no longer purchase bottled water to supply at our workshops. Good for the environment and good for our ever shrinking budget!
Facts about bottled water:
- Bottled water isn’t necessarily purer than tap water. An investigation by the Environmental Working Group, released in October 2008, found chemical contaminants in every brand tested — including disinfection byproducts, fertilizer residue, and pain medication. 
- 80 percent of plastic bottles end up in landfills or are burned in incinerators  that’s 3 billion pounds of waste annually. 
- 17 million barrels of oil are used in the production of water bottles annually…enough to fuel 1 million cars for a year.
