Abstract

In recent years the total area of solid municipal waste landfills and dump sites, including overloaded, which violate the norm of ecological safety and are the objects of the intensive ecological loading has considerably increased. This may cause  the pollution of the environment by the microorganisms (colibacilli bacteria, streptococci, staphylococci and ascarids), causing bacteriological contamination of the soil and ground water. Determination of the regression dependence of the level of the microbiological pollution by general coli group bacteria of the ground water on the distance to the solid waste landfill is an urgent scientific-engineering problem.

Aim of the research is to determine the regression dependence of the level of microbiological pollution with the general coli group bacteria on the distance to the solid municipal waste landfill. In the process of the research the method of the regression analysis of the results of single-factor experiments and other paired dependences with the selection of the rational type of the function from sixteen most widely spread variants by the criterion of the maximum value of the correlation factor is used.

Regression was performed on the base of the linearized transformations, which enable to reduce the non-linear dependence to the linear one. Determination of the coefficients of the regression equations was carried out, applying the method of the least squares by means of the developed computer program "RegAnaliz", protected by the certificate of the State Registration of the rights to the copyright object. Adequate regression dependence of the level of microbiological pollution with the general coli group bacteria of the surface water on the distance to SMW landfills was obtained , the given dependence is used for the determination of the safe distance for the location of SMW landfills from the sources of the drinking water by the index of the level of microbiological pollution with the general coli group bacteria of the surface water. Graphic interpretation of the dependence of the level of microbiological pollution with the general coli group bacteria of the surface water on the distance to the solid waste landfill is constructed, it enables to illustrate this dependence and show the coincidence of the theoretical results with the actual results on the level of 0.99996.
