چکیده

Safety drinking water providing is one of the main purposes for community development and improvement. Having a healthy community is related to the safe drinking water. In this study, we surveyed the microbial quality of 50 residential places (motel) located in the coastal zone of Babolsar city. A total of 50 samples were collected from 50 wells in winter 2017.We examined the Total Coliform,E .coli , pH , Turbidity and residual chlorine in laboratory of the health network. Most Probable Number (MPN) was done on nine tube cultivation basis. And also Turbidity test was done using HACH turbidimeter . Results show that residual chlorine content in all wells was zero because of failure to install disinfection facilities And the Total Coliforms,HPC, Turbidity,E.coli, pH, 2%,94%,16%,100, of drinking water samples in this report were desirable respectively .Based on the results obtained from laboratory results all wells had microbial contamination. In order to provide safe water, it is recommended that the city water network be installed by the city's water and wastewater company and the branches be handed over to the motels or the water disinfection facilities be installed by the owners of the motels.
