Evaluation of Physical and Chemical Components of Drinking Water and Evaluation of Drinking Water Quality in Rural Areas of Ilam#

In many developing countries, water sources are not well protected# however, many people depend on these water sources for their daily consumption# therefore, this study investigated the physical and chemical composition of drinking water and evaluated the quality of drinking water in rural areas of ilam# the mean water surface temperature of the wells is 19#6 ° c and the average ph of the sample is 7#6#the case study method is a case-control type# the number of 12 water samples (12 wells) is in the most significant areas to be used for potable water purification# modeled thermometer thermometer - approx# 5000 dr# finally obtained in spss software#physical and chemical parameters were analyzed according to the procedures outlined in apha (standard methods for water and wastewater investigation, 21st edn# washington dc, 2008)# the results showed that total hardness values of 327#6 mg / l, 16#65 mg / l chloride, 63#25 mg / l sulfate, 14#51 mg / l nitrate, and 76#62 mg / l ca were detected# statistically significant difference (p <0#05) was observed among all parameters from different sites# most of the physical and chemical values were within the who and iran's drinking water quality standards# components beyond the quality standards may cause health problems in local communities# therefore, careful monitoring and purification of water is required to ensure the quality of resources before human consumption#
