Providing adequate supplies of fresh water to the world’s seven billion plus population is a serious issue facing individuals, communities, governments, agriculture and businesses. Most fresh water is used in agriculture.

During the past few decades, much progress has been made cleaning up and preventing water pollution. Municipal water supplies have been improved, and new facilities have been built in many under developed countries. Nevertheless, in many cities and towns around the world domestic water is still unsafe to drink. Most governments have programs dealing with water issues, but they are usually underfunded and lag behind current needs. The double edged sword of providing potable, safe water for domestic use and dealing with polluted water confronts most government programs.
