Abstract :

Water quality assessment mechanisms vary according to continuous water quality testes and examinations; therefore. A coliform bacterium is an indicator of water pollution by sewage, and proves the presence of microorganisms also pathogenic, which coexist with the bacteria of the group mentioned. Micro–organism had been counted using most probable number method, after it‘s been collected from the houses directly from faucets. The contaminated samples cultivated in nutrient oth, then by using streak plate method applied to differential and selective MacConkey agar, blood agar, and EMB, then conformational test of hemolytic in Blood agar, and Indole citrate. The biochemical tests had done by APITM tests. Current WHO guidelines recommend Fecal Coliform as indicator of the effectiveness of disinfection processes, and as index organisms for potential prescience of fecal contamination and waterborne pathogens. The results were positives for nutrient agar, blood agar, MacConkey agar, respectively. Metallic sheen growth on EMB as selective media for E.coli confirmed the results and proved the contamination of drinking water. the samples showed positive results for the biochemical tests, the diagnosis was confirmed by API20 tests. Yet, It is a part of new market era, especially after the system collapse and the underground biases of cities were destroyed, the merchants encourage the neglect of government departments to increase their profits from water bottled. For some, it‘s used as a political era to compare the healthy status of poor people before and after the war.
