The ecological database WATERS based on constructing different indices on various water quality characteristics

The ecological approach to diseases facilitates understanding of the reasons for the multiplicity of causal factors and the finding of those on which the preventive measures will be easily and succesfully directed. This is the reason why the integration of space data is necessary for getting insights into the existing conditions from the ecological point of view. The ecological need to sum up the research findings and to estimate the future water quality trends by observing the relevant parameters as influential environmental factors for the health of the population resulted in a relation database WATERS.The water quality was evaluated by using the quality index based on the following nine parameters: temperature, mineralization, corrosion coefficient, dissolved oxygen, biological oxygen demand, total N, protein N, total phosphorus and total coliform bacteria. Individual indices are also presented, i. e. those related to total N and total phosphorus, total coliform, corrosion coefficient and the mineralization indicating the change in the water quality. Thus it is possible to evaluate which parameter or group of parameters influence the water quality. From the ecological standpoint the database WATERS integrates waters data and it is suitable for the several years study of trends of existing water supply conditions with spetial survey of the results of water quality analyses in view of the recognition of the actual pollution groups and individuals.It is important to recognize the actual pollutants which are important factors in health problems of the general public and individuals. One gets information and plans necessary for interventions so that is possible to apply computer techniques to the water pollution control
