Subject area	Environmental Engineering
More specific subject area	Water treatment
Type of data	Table and figure
How data was acquired	In 30 points of the drinking water network for six months, 176 water samples were collected, stored and transferred to the lab using standard methods and the drinking water quality; turbidity, pH, temperature, total dissolved solids, total hardness, calcium hardness, alkalinity, nitrate, phosphate, chloride, sulfate and free chlorine were measured. Alkalinity, total hardness and calcium hardness were measured by titration method; the hydrogen ion concentration (pH), temperature and total dissolved solids were analyzed with the HACH Multiparameter HQ 40d. Turbidity were measured with turbidimeter (model P2100 HACH); nitrate, phosphate, chloride, and sulfate were determined with HACH DR 2500 spectrophotometer, free chlorine were measured with HACH DR890 and compared with internal standards.
Data format	Raw, analyzed
Experimental factors	The mentioned parameters above, in abstract section, were analyzed according to the standards for water and wastewater treatment handbook.
Experimental features	The levels of physical and chemical parameters drinking water were determined.
