Answer:Reducing the level of contamination of water is the aim of a new line of research. Chemists are investigating chemical treatment capable of eliminating contaminants dumped by industry, in order to reuse the waste water. Industrial activity is one of the principal causes of contamination in water, given that industry dumps large amounts of chemical compounds into rivers that are not capable of degrading by themselves.
