China's state news agency, Cinhua, has reported that pollution in the river system in central China has forced the closure of schools in the area and cut water to 200,000 people. The water in the river system was red and bubbly.
According to Xinhua, tests showed there were increased levels of ammonia, permanganate and nitrogen. These chemicals are generally used in metal cleaning. Government officials are using water from the Changhu Lake to flush out the polluted rivers.
