Significant role in increasing the organic matter content in the water of open reservoirs is the descent into ponds of untreated or inadequately treated domestic and industrial wastewater. That organic matter is the overriding cause of the smells and tastes of water. In some cases, adversely affect the quality of water in open reservoirs chemicals used as fertilizers and pest control.
Fertilizers increase in water content of nutrients and thereby stimulate the development of aquatic vegetation, livelihoods and the death which affects the taste of water.
Pesticides used for pest control, getting along with runoff into water bodies, often worsening sanitary quality of water and, in particular its flavoring properties.
Because of the difficulty of the individual analytical determination of diverse organic substances in natural waters, resorted to the total assessment of their content, for example by determining the oxidation. Results of the determination expressed in the oxidizer flow (or the equivalent amount of oxygen) used for oxidation under these conditions in the water reducing agents.
The most common methods for determining the oxidizability of dichromate and permanganate, the latter is less reliable, since potassium permanganate is oxidized only part of the most easily oxidized substances. Typically, the value of bichromate oxidizability 2-3 times, and sometimes more than permanganate oxidation.
In determining the oxidizability of both species are oxidized not only in the water of organic substances, but also some inorganic, such as ferrous iron, hydrogen sulfide, nitrites. Therefore, oxidation characterizes the content of organic substances in water, only approximately.
For the total score in the water of organic pollutants in recent years are beginning to apply the method of water sorption of organic substances and activated carbon from coal extraction of these substances with chloroform.
To obtain the extract through a column loaded with activated charcoal, filtered several cubic meters of water and after drying the coal is extracted sorted coal organic contaminants chloroform.
Not all organic matter that may be present in natural waters, activated carbon adsorbed. Consequently, the method of carbon-chloroform extract gives an idea of the artificial water pollution.
