Water purification is the most urgent task More over, this task is complicated by Water purification is the most urgent task More over, this task is complicated by the day: the relevant engineering works order deteriorated, no longer meet the demands of today and the technology. Established a decade ago, water treatment system was not designed for the modern state of the volume and purified substance. And the fact that the necessary actions to maintain the existing system in a functioning state is not manufactured or produced in insufficient amount, leads to the fact that many elements of the water industry are dangerously unsafe for the public.

S. beaches are closed at least once because of water pollution Over 73 different kinds of pesticides have been found in the groundwater that we eventually use to drink 1. 2 trillion gallons of sewage, stormwater and industrial waste are discharged into U. S. waters every year 40% of U.

First, it is reflected in the fact that the cost of the state monopolies First, it is reflected in the fact that the cost of the state monopolies and to protect the environment has increased dramatically. Second, the adjusted production purification technology because of "environmental industry", "ekobiznes" International market for environmentally friendly equipment and environmentally friendly products. Awareness of environmental issues has led to green economic development in industrialized countries. . Third, was established a system of laws and institutions to protect the environment (relevant ministries and agencies). Programs were developed environmental development of individual countries and regions. Fourth, the efforts of international coordination in the field of environmental protection.
