Environmental Assessment of Indicators of Contamination of Wastewater and Household Tanks in the Areas of (Mansour - New Baghdad)

Abstract

This research is based on the study of some characteristics of drinking water (physical , chemical , biological) in the areas of ( Al-Mansour and New Baghdad ) in Baghdad governorate by taking random samples of water (liquefaction , house tanks) for some homes in the two study areas during the specified months (February , July) for 2018,  It was found through the results of the researcher's analysis that some indicators of pollution in water samples (liquefaction , house tanks) increased as the concentration of turbidity in the liquefaction water increased as a result of overtaking the water transmission lines and breaking it in the two study areas compared to water ( house tanks) during the two months of the study as it did not exceed the permissible limits and the reason is due to the continuous sedimentation of turbidity at the bottom of the tank , and it was also observed through laboratory analyzes that the high concentrations of (electrical conductivity , chlorides) in water samples ( liquefaction , household tanks ) during the two months of study , and the reason is due to mixing of wastewater As for the bacteriological analyzes of water samples (liquefaction, household tanks) water samples  (liquefaction ) did not record any presence of bacteria, the reason is due to the use of (chlorine, alum) in water treatment projects in appropriate quantities It works to eliminate the presence of bacteria , as for water samples (house tanks) the presence of fecal coliform bacteria has been recorded , and the reason is due to the availability of appropriate conditions A feature for the growth and spread of bacteria in it .
