Residues of some medicals and fertilizers used in agricultural areas can reach to some receptors through some processes such as irrigation and surface waters. These natural receptors are rivers, lakes and seas. The materials coming from agricultural areas have more destructive effects on the lakes and rivers since these are smaller. The most pronounced pollutants coming from agricultural areas to rivers and lakes are pesticides and fertilizers which are known as a source of nitrogen and phosphor. Chemicals in some areas where pesticide were used are mixed into rivers and lakes through that way and reach to water habitats and organisms. On the other hand, this causes to increase organic ratio, eutrophication and for ecological balance to be destroyed. Pathogens are transmitted to surface waters with human and animal wastes and then these contaminated surface waters threat human health. An important amount of pathogens is distributed to receptors through use of wastewaters for irrigation. In order for this negative effects to be removed, in order to save rivers and lakes, wild irrigation must be stopped, the direct approach of wastewaters into the rivers and lakes must be prevented, the use of fertilizers and pesticides must be controlled, mechanical and biological war must be strengthened. The sustainable ecological living areas can be constructed by taking the water sources and biological kinds under control with these precautions.
