| Providing safe drinking water, particularly in rural areas and isolated places, has the highest priorities in
communities. The present study was aimed to investigate water quality, including physicochemical, corrosion
and scaling properties, in rural areas. Samples were collected from 9 villages in Marand, northwest of Iran, both
in spring and summer seasons. Principal component statistical analysis (PCA) along with water quality index
(WQI) was used to better interpret the obtained results. The results indicated that some physicochemical parameters
were outside the range recommended by WHO standards. More than 50% of the samples were corrosive
both in summer and spring seasons. It is observed in some areas that temporal variation can change water
quality; furthermore, samples taken in summer exhibit poor quality when compared to spring. It can be suggested
that in order to provide safe drinking water, authorities, through monitoring and supervisory actions, should
regularly evaluate water quality. |
