Abstract
The principal reason for monitoring water quality has been, traditionally, the need to verify whether the observed water quality is suitable for intended uses. The present study was conducted on Al Kufa river in Al-Kufa city in the aim of studying the concentration levels of some water quality parameters (BOD, PO4, NO3, pH, TU, Cl, and dust particles).
Samples of raw water were collected and analyzed from Kufa river station during a period of eight months, starting from November until June 2010. The purpose is to assess the level of parameters measured and their effects on the river. Statistical analysis used to describe the relations between parameters of water quality with regression analysis done by using "Data Fit" program version 9.0 software.
This study showed that the discharging of domestic sewage, detergents, agricultural effluents with fertilizers and industrial waste water from adjacent areas causing some contaminants increased.
It was noticed that the NO3 has highest positive correlation with PO4 and pH has highest negative relation with PO4 and NO3,
Finally, precipitated dust particles have highest negative correlation with pH as a result of acidic chemicals in dust particles.
