I am an active member of Green Peace India.  Now I go through the website in which I read the blog post, posted by Beau Baconguis who is a Toxic Campaigner with Greenpeace Southeast Asia.  It is very important one and interesting one. I give the link of the blog.                  http://www.greenpeace.org/international/en/news/Blogs/makingwaves/the-power-of-      knowing-whats-in-your-water/blog/42353/
