Now and then I run across posts on various tea websites recommending that people use bottled water for brewing tea. The rationale is simple: water quality is one of the most important factors in brewing the best possible cup of tea. I agree with this statement, to a point (although honestly, I think other factors like steeping time and temperature are often more influential than subtle differences in water quality). More on these factors on the RateTea article on brewing tea.
Is bottled water higher quality?
A 2005 edie article about bottled water discusses a policy statement of the Chartered Institute of Water and Environmental Management (CIWEM), and also interviews their executive director, who offers a scathing critique of bottled water. CIWEM claims that public perception of bottled water has been driven by marketing and not facts, and that there are actually stricter standards for quality in place for tap water than for bottled water, both when it comes to chemical content and bacteria.
In 2008, the Environmental Working Group also conducted an analysis of bottled water. The results strongly validated the assertions made by CIWEM, finding 38 pollutants in 10 major brands of bottled water, including disinfectants and known carcinogens at levels that exceeded legal safety limits. Over one-third of the chemicals are not regulated in bottled water. Also, 4 out of the 10 brands were found to be contaminated with bacteria. The analysis concluded that the purity of bottled water could not be trusted.
Unsustainable: Bottled Water is a Resource Sink:
Quality issues aside, there are other reasons to avoid using bottled water. The Pacific Institute looked at 2006 water consumption and produced a fact sheet about bottled water and energy use. The production and bottling of the water was estimated to take 17 million barrels of oil in this year, and that does not include transportation costs. Also, 3 liters of water are used for every 1 liter that gets bottled. Transportation is a major issue.
Sustainability is of utmost importance to me. Even if the quality were somewhat higher, I cannot see myself drinking bottled water unless the water in my area were unsafe for human consumption. Given that the evidence points to bottled water being considerably less safe, there is simply no choice for me. Delaware water may not taste great but it's what I will continue drinking and brewing my tea with.
