- The household and industrial wastes that have been accumulated during the last 40–50 years organized and spontaneous landfills (garbage dumps) pollution of the natural water bodies near locations. As results of precipitation and solar irradiation, the drainage of water formation occurs; such waters are polluted with harmful and toxic ingredients. The known indices of pollution of industrial and surface waters as well as the technique for determining the class of danger posed by solid household wastes were analyzed. The application of this technique to liquid wastes is suggested, since the change of aggregate state must not restrict its application; on the contrary, a new useful unexpected result can emerge with this. A rather simple dimensionless index of toxicity was chosen on the basis of the following examples: composition of the drainage waters of a specific landfill, content of harmful ingredients in them, excess ratio of their maximum permissible concentration. Such an index takes into account the maximum permissible concentration of the harmful substance in the ground, as well as the fraction of the harmful ingredients in the total mass of the liquid waste. Using the dimensionless index of toxicity, the bar charts were drawn, from which the sequence of removal of harmful components from the liquid mixture can be determined, starting with the component with the least value of dimensionless index of toxicity which characterizes the most dangerous component.
