Determination and statistical analysis of the water quality of the Riva River

In this study 13 parameters which are pH, temperature, dissoluted oxygen (DO) electrical conductivity (EC), salinity, suspended solid, volatile suspended solid biological oxygen deprivation (BOD), chemical oxygen deprivation (COD), total phosphorus, nitrate nitrogen (NO3-N), ammonium nitrogen (NH4-N) and total kjeldahl nitrogen were measured (1716 results) through 33 water samplings which were taken from 4 designated place where are different in Riva River between the dates of 15th January 2010 and 20th June 2011.Along statistical analysis, Correlation Analysis, Spatial and Temporal Description Analysis, Variation Analysis (ANOVA), Spatial and Temporal Homogeneous Group Analysis were constructed. The relationships between those analysis and parameters, their alternations according to time and association between the different places were investigated. Due to time mean of 12 parameters change (Except TKN) and solely 4 parameters? mean show changes in respect of statistical accounting.Including after raining, rainless and rainy; total coliform, fecal coliform and fecal streptococcus measurments were carried out at 3 times. Besides Total heterotofic Bacterium measurement was accompanied in the last sampling.The microorganism measurements shows what the first point of the water is influenced negatively by the waste treatment facilities where is located space in front and immediate precaution must be taken.According as the chemical parameters, to built the proper sewage treatment plant is absolutely necessary at the sampling places which ware stated precisely
