If China thinks it is alone they are not watching
the US. We are fast following them with the extent of our drinking water contamination. One cup of MTBE contaminates 5 million gallons of ground water. We have
had severl hundred thousand leaking gas station tanks and every time someone spills a gallon of gas when they fill the outboard, the smow mobile , the lawn mower, etc.
the contamination goes right to the acquifer. One company that has been succssful in cleaning up drinking water is Emerald Bay Environmental Services. They have a proprietary formula that works. They just cleaned up a whole neighborhood in MA. Try- emeraldbay@hughes.net.

It means, scarcity of potable water is going to be an ubiquitous phenomena.

china is now facing the result of its industrialization which is earned by china over the last three decades. It is not only facing the crisis of polluted water but most of population is living with polluted air conditions as well. China shares 30 percent market of textile and almost same the coal mines of the world, which is also a great cause of pollution. The next five year plan proposed by chinise government has concluded all these measures, but i think its too late. and China has to spend huge amount of money to back on the track which can take it back China to its inception.
