The study of microbial contaminants and some physical and chemical characteristics of the bottled water circulating in Samarra city and comparing with ordinary water

This study included examined of the microbial and chemical content some physical properties bottled water manufacturers locally circulating in city Samarra markets. It was counting number colonies both bacteria fungi, measuring pH value electrical conductivity suspended solids total distress, bio-oxygen demand as well concentrations each calcium, sodium, magnesium, potassium, nitrates, iron, fluoride, chloride sulfate. The has shown higher contamination majority samples that 36% studied free aerobic 90% fecal 22% molds yeasts when comparing contaminants combined found 13% which is devoid three contaminated species 87% contains all these pollutants, or them either. elements compounds, showed 54% contained an increase potassium 16% contain iron while 4.5% fluoride polluters together [microbial chemical] only one sample pollutants thus deemed unfit for human consumption.
 When compared to regular it last highest contaminants, but results examination close.
