Abstract :
The purpose of this study is to investigate the water quality of the Diwaniyah River in Iraq based on environmental criteria and Its health status is usually monitored by periodic tests of a river water sample. Sampling was performed at two points located in the north and south of the river in two seasons of spring and summer. Temperature, electrical conductivity, acidity, dissolved oxygen, biological oxygen demand, total soluble solids, suspended solids, alkali metals, turbidity, nutrients, heavy elements and bacterial status were measured. Analysis of variance test to investigate the effect of time and place on the test results showed that time (season) has an effect on water temperature and oxygen and except for the temperature and the amount of oxygen, none of the measured values are a function of place and time and are at the standard level. The status of the parameters is normal according to the standards of the World Health Organization (WHO) as well as the national standards of Iran, the United States and the European Union.The proximity of laboratory values to the limit of departure from the standards, has raised concerns about the current situation that if the growth of pollution sources, river water will be unusable. Controlling and monitoring the entry of various sewage and municipal waste and repairing drainages are the most important measures for the Diwaniyah River.
