The Effect of Heavy Metals on Khorramabad Water Quality Obtained Using Standards (National, World Health Organization and EPA)

According to the economic and industrial growth and the production of different kinds of compounds and chemical materials which provided by human for their welfare using natural resources and in this direction , they came undesirably materials such as toxic and heavy metals into nature which result in serious risks and problems for both them and their surrounding environment. The research area of this, study is the city of Khorramabad that is located in west of Iran, central of Lorestan province; In this study, in order to determine the quality of drinking water of studied area, 23 fountains and wells circles related with heavy elements including (chrome, molybdenum, copper, zinc, barium, cobalt, aluminum, lead, cadmium, nickel) during three years (2011-2013) was used. In order to determine the rate of minimum and maximum concentration of elements among studied area’s fountains and wells, Excel software was used. Then, in the software of geographic information system (GIS), The map interpolation method of each heavy elements in each supplier resources of drinking water has produced and amount of each element and parameter and stated amounts by Iran national organization, world Health organization (WHO), America’s environment organization (EPA) have been compared and the rate of pollution of each water resource should be determined. With respect to present data or information, the rate of maximum and minimum of heavy pollutions and elements in each of studied water resources determined. the results showed that the concentration mean of chrome, molybdenum, copper, zinc, cobalt, lead, cadmium and nickel is lower than national standards level, world health organization (WHO) and America’s standard (EPA), but in Motahari’s fountain, the rate of chrome heavy metal is higher than standard level (WHO). The mean of barium element concentration in resources was lower than national standard level and was higher than standard level (WHO) and (EPA) standard in all resources. The concentration of aluminum element is lower than national standard and is higher than standard level (EPA).
