CORRELATIONS BETWEEN THE GROUPS OF PHYSICAL AND CHEMICAL INDICATORS OF THE SIRET WATER BETWEEN 2008 AND 2009

In the present study aims at making functional links or stochastic ties - correlation based on regression equation right of physical parameters (flow, temperature, pH) and chemical parameters (DO, BOD5, CCOMn, COD) between physical parameters and between chemical parameters. The comparative study was made between the determined values of physical indicators (flow, temperature, pH) and the values of chemical indicators in order to determine correlations between physical and chemical parameters that determine the quality of water and the cumulative effects of pollutants on the values of quality indicators. This study aims at highlighting the existence of a synergistic (cumulative) context of factors, with particular importance in assessing the self-cleaning capacity of surface waters. For this purpose we used experimental data on the mentioned parameters, from the review of water samples from three sites of the Siret river in 2008-2009.
