Investigation of Physicochemical and Microbial Parameters of Doogh River Water and the Effect of Adjacent Felman Wells on Decreasing These Parameters in Kalaleh city During 2012-2016

Background: Water resource management in order to preserving and supplying of high-quality water, plays an important role on communities health. For this reason, humans have always used different methods to provide high-quality water. One of these methods is the use of Radial Collector wells. In this study, the effect of Radial Collector wells on the microbial and physicochemical quality of Doogh River during 5 years has been investigated. Methods: In this study, we assessed some water quality parameters on Dough River (DR) and its adjacent Radial Collector Well (RCW) which supplies water shortage of Gonbad Kavous city, Golestan province, Iran. For this purpose, monthly samples during 2012 to 2016 were collected from DR and RCW, then parameters included nitrate, phosphate, turbidity, pH, fecal coliform, and temperature were measured. Finally, effect of time variation and infiltration of water from DR to RCW on qualitative parameters was analyzed. Results: According to the results, nitrate, phosphate, turbidity, pH, and fecal coliforms significantly decreased during infiltration process (P-Value <0.05). In addition, the time variation of nitrate, phosphate, turbidity, temperature, and fecal coliforms had significant difference. Conclusion: The present dataset demonstrated that RCW has a good efficiency for reduction of measured parameters. Also, monthly variations can be effective on water quality of resources.
