Effect of Wastewater in Some Physical and Chemical Properties of the Chabaish Marshlands

Abstract

The study examined the effect of wastewater from the sewage plant in Al-Chabaish on the quality of marsh water, which in turn affected the living organisms, especially the fish, which are abundant in these waters. Three stations were selected in the study area. The samples were collected  monthly for six months, from   March to August 2017.

Some of the physical and chemical properties of the Chabaish marshlands were  measured. The air  temperature  ranged between (19-34) ᵒC , water temperature was between (18-33) ᵒC, while the effective  phosphate value was between( 0.014 – 0.52) mg / l and the active nitrate between( 0.7 - 4.9) mg / l, sulphate between (570 – 962) mg / l, electrical conductivity was between (3800 – 5860) μs / cm, dissolved oxygen between( 4.7 - 7) mg / l and potassium between( 21.5 – 68) mg /l, while the turbidity was between (24 – 171) mg/l, The total  solids suspended were between( 1118 – 3432) mg / l and the pH was( 6.71 - 8.2) , The chloride content was between( 350 – 2000) mg / l, totalhardness between( 200 – 1800) mg / l, calcium between( 48 - 368 )mg /l, magnesium  between ( 9.6 - 52 )mg /l and sodium between (430 – 1560) mg /l, While the  biological oxygen demand (BOD₅ )was( 3.3-5) mg /l.
