Industry is responsible for a large amount of pollutants including ones that pollute water. Legislation has been passed forcing industry to make efforts to clean up their waste. Through reducing the waste that they produce, it has been possible to reduce the amount of pollutants that enter the water cycle. Proper disposal of industrial waste has also had a large impact on the amount of pollution that plants and other industrial facilities introduce into the environment and specifically into the water cycle. Changing the products that they produce has had some impact. By making products that will be disposed of, degradable industries have been able to reduce the lifetime of possible pollutants, including plastics. Continuing to make process cleaner to reduce waste, better disposal of any waste created and the creation of products that, after use, result in less pollution are all ways that industry can continue to reduce their contribution to water pollution. Legislation continues to require these efforts and has prompted action to clean up the pollution already in existence.
