Existences of some elements in water are necessary for human health, but deficiency of many them can cause problems. At this research chemical and physical parameters of produced water in Ilam Water Treatment has determined and compared with Iran and world health organization (WHO) standards. In this study, samples were analyzed twice per month during 12 months 2008. Altogether in this survey, 16 physical and chemical parameters were measured in produced water of Ilam Water treatment plant. During this study, 24 samples were taken and analyzed according to the latest addition of standard method manual. Data were analyzed using the SPSS and Microsoft Excel software packages. Then the results compared to drinking water standards. The physical and chemical parameters of produced water of Ilam Water Treatment Plant are in range of WHO and Iran drinking Water standards and only fluoride value is lower than Iran standard limits. The chemical and physical quality of produced water does not have any health hazard problem. Fluoride is just lower than the standard range and many people use some methods to overcome this problem. Key words: Chemical quality Physical quality Ilam water treatment plant Water standards INTRODUCTION inconsumable because of taste, odor and insufficient The water currently contains some dissolved chemical constituents. The value of a guideline is constituents, suspended solids and dissolved gases. explanatory of the concentration of a constituent that Some of mineral constituents are essential nutrient but didn’t introduce a visible disorder because of long period higher concentration than permissible values may create consumption of it [1]. disorders. Monitoring the drinking water quality is There isn’t any guideline for pH based on health achieved with protection of water sources, controlling of impact. Although the pH doesn’t have undesirable direct treatment processes and water quality management of effects, but it is one of the most important parameters in convey line and distribution network. Setting of drinking water operation control. At published guideline guidelines is related to areal and national regulations by WHO in 1984, based on aesthetic aspect, the pH value which are based on social, economical and cultural in drinking waters established in the range of 6.5-9.5 [2]. conditions. Importance of chemical constituents differs The source of chloride in drinking water is due to natural with microbial agents. Unlike microbial agents, that sources, domestic and industrial wastewaters, urban need a short time to show their impacts, the chemical runoffs which contain divalent salts and intrusion of constituents need a longer time to show their impacts. saline waters to fresh waters. Heavy concentration of the In many conditions, it has seen that water is chloride may cause corrosion in the distribution networks. clarity of water. Guideline values are available for many of
