increasing population and rapid economic growth as well as lax environmental oversight have increased water pollution. Therefore‚ deterioration of drinking water quality continues to be a major problem. Continuous emissions from manufacturing are the largest contributor to lowered drinking quality across the country. China’s major river systems exhibit the scope of the problem. Perhaps 70 percent of their water is so polluted that it has been deemed unsafe for human contact. In addition to untreated sewage
