Water Quality Assessment of the Tigris River in Amarah City, Maysan Governorate, Iraq

According to the results of the water quality assessment conducted in Amarah City, the physical, chemical, and microbiological characteristics of the Tigris River have drastically decreased particularly true in contrast to the water that enters the city (from the upstream) and exits it (outfall).The amounts of nutrients (phosphate and nitrate), organic matter (BOD and COD), and dissolved salts (as determined by a conductivity test) are markers of significant waste water, agricultural, and industrial water pollution. These results indicate that environmental restrictions must be enforced immediately, and effluent must be cleaned before being released into waterways.
