Assessment of Physical, Chemical and Microbial Quality of Drinking Water of Jiroft City

The physical, chemical and microbial properties of drinking water are the basis for judging its drinking potential. Undesirable changes in these parameters can threaten the health of consumers. Therefore, the aim of this study was to evaluate the physical, chemical and microbial quality of drinking water and compare it with national standards and the Environmental Protection Agency.

33 samples from 11 stations in the water distribution network of Jiroft were collected directly. Physical and chemical tests include Electrolytic Conductivity, pH, Turbidity, Residual chlorine, Total soluble solids (TDS), Fluoride and Nitrate were done based on the standard methods and microbial tests also included total coliform and fecal coliform with multi-pipe fermentation method was applied. This study was performed in the 2017 year.

The average of the measured parameters were included electrical conductivity 720.69 microsiem/cm, turbidity 0.53 NTU, pH 7.86, total soluble solids 397.8, chlorine residue 0.32, nitrate 11.77 and chlorine residue 0.66 mg/l. Other than Nitrates and TDS, which were above the national standard, other parameters were in national standards and EPA drinking water. Also, the health quality of the water distribution network in Jiroft was not a problem, and it was at the national level and the EPA.

In general, it can be said that the drinking water of the Jiroft distribution network is without problem in physically, chemically and biologically aaspects and it is safe to drink.
