Diffuse pollution-principles, definitions and regulatory aspects

WithR. Hranova

Definitions and basic classifications of water pollution in general and diffuse pollution in particular have been presented. The “language” of water quality, or the basic characteristics, which define it and allow the identification, assessment and control of pollution have been listed and explained briefly. The process of diffuse pollution generation has been described and the main sources mentioned, which would be the basis for the implementation of source control measures. Diffuse pollution is associated in most cases with polluted runoff and its evaluation and control would rely heavily on the correct estimation of runoff characteristics, therefore basic principles and methods in this direction have been emphasized. Definitions and principles with respect to regulatory instruments used to control and manage pollution, have been presented and different approaches and philosophies applied internationally in this field, have been discussed.
