摘要

Water is an initial necessity for living and one of the most useful substances in nature which is vital for human living and civilization. Therefore, it is important for everybody to be aware of the quality of water. The objective of the present studywas to determine the microbial and chemical quality of drinking water in the rural areas of the central district of Boyer Ahmad. The present descriptive sectional study was performed in the rural areas of the central district of Boyer Ahmad. In this research 79 samples were tested for microbial quality study, and 21 for chemical quality study. The obtained results were analyzed using SPSS software. Based on the analysis of the tests, it was specified that in 100 percent of cases, the concentration average of measured chemical (Except remaining chlorine and floured) and microbial (fecal coliform) parameters in the standard limit, but 24% of measured microbial cases contained coliform. With respect to the fact that acceptable quality and quantity of drinking water is a very important matter that people are facing with, and on the other hand, it becomes a more serious problem over time, by increase of population and polluting sources such as industries and agriculture, a fundamental consideration to thematter is necessary with respect to the fact that the highest. Contradiction is in the chlorination rate of drinking water; therefore it could be evidence of incorrect management and in affection, the improvement of water resources and observance of standards of drinking water is necessary to prevent contamination of water to other coliforms.
