Abstract
Microbial contamination of water persists to be a major problem; the usual source is human and animal fecal matters that have entered the water systems . The presence of bacteria and pathogenic organisms is of great concern when considering the safety of drinking water, as pathogenic organisms can cause intestinal infections as dysentery, cholera and hepatitis, and other serious illnesses . Water samples for laboratory examination were collected from 14 areas all over the Basra governorate. Six samples were taken from each area . The total number examined was 84 samples, which were classified as : 42 samples from Reverse Osmosis (RO) Drinking water ,and 42 samples from Tap water. Each sample was submitted for direct microscopic examination, then culture was done using appropriate media for the identification of microbial contaminants (bacterial and fungal). Tap water samples were found to be highly contaminated with many types of pathogenic bacteria such as Coliform, Salmonella ,Shigella ,Pseudomonas, Candida and other types of fungi in all samples, whereas R.O. water samples also were found contaminated with Candida and other types of fungi in all samples of the tanks from which the samples were collected . In conclusion the main results were that drinking water in Basrah is not safe from the microbiological point of view.
