To study a maintenance of chlorine in soils and natural reservoirs of Sumy, in a drinking-water of different administrative districts of the city. Electrometric study of solutions, potentiometer EPP-0,9. It is shown that the nature and degree of endemic diseases affect biogeochemical active forms of fluorine. Most important among which is the fluorine ion, and the presence of other elements that determine the synergistic activity of fluoride in drinking water. The cause of the disease of population is the consumption of water with defective concentration of fluorine, a high concentration of strontium, sodium, and low concentration of calcium. Concentration of water-soluble fluorine in the soils of the city corresponds to the sanitary standards and considerably exceeds sanitary standards in a direct from the source of contamination. In fresh water and in unsalt soil it is possible to determine the degree of dechlorination of pesticides, brought in concentrations 5-50 mg/l (water environments) and 5-50 mg/ kg (soil).The error of determination does not exceed 10-20 % and depends on the background level of chlorides, the concentration of the pesticide and maintenance of chlorine atoms in the molecule.
