ABSTRACT. The of the frequency of diseases among the adult population of the Tambov region with the mineral composition of drinking artesian waters of this region had been studied by means of the method of local environmental standards. The boundaries separating the «high» and «low» incidence rates had been identified. The principle of the method is based on the establishment of permissible limits for the two quality classes from the factor and the inadmissibility of both too high and too low values of the factor. A high frequency of diseases are associated with significantly lower concentrations of arsenic (more than 0.005 μg / l), copper (more than 0.020–0.040 μg / l), molybdenum (more than 3–10 μg / l), calcium (more than 105.2 mg / l) , nitrate of ions and ammonia, than the maximum permissible concentrations regulated in current regulations. For fluoride ions, the limits of norms are close to hygienic standards, for some substances the boundaries are softer (total iron content is 1.47–2.3 mg / l). In addition, the lower limits of the norm were found for essential elements (calcium – 76,4 mg / l, magnesium – 22,0 mg / l, chlorine – 41,2 mg / l, fluorine – 0,35–0,39 mg / l, iodine – 0,03–0,10 mg / l, the sum of sodium and potassium – 13,1 mg / l). The presence of links between indicators of the quality of drinking water and the incidence of the population indicates the need to clarify the maximum permissible mineral concentrations for drinking water.
