The study was conducted on three ditches near schools and health center within three residential neighborhoods. Chemical laboratory tests (BOD, COD, TSS, TN, TP, NO2-, NO3-, SO42-, Cl-, CN-, pH, T, DO) were proceeded on this water and it was found that the water is high polluted in sewage water compared to the sewage entering the treatment plant in the city and comparing with samples of water taken from ditches outside the city (as a standard sample).
