  Lead and Copper Rule is one of the indirect methods which is applied to determine the corrosion potential in drinking water distribution networks.  The objective of this study is to determine the corrosion potential ofAhvazdrinking water distribution network. In this study, 76 sample sites were selected. The sites were the inlets and outlets ofAhvazwater treatment plants as well as the consumers’ houses cold water taps. The samples were taken after a minimum detention time of 6 hours. The concentration of lead, zinc and copper was determined through atomic absorption technique. The obtained data were analyzed using SPSS software version 11.5 for statistical tests. The averages of six rounds of corrosion measurement are as follows: lead (8.48 μg/l), copper (168 μg/l), and zinc (3180 μg/l). Also, 16.67 and 27.27 percent of the samples have concentrations higher than USEPA standards for lead (15 μg/l) and zinc (5,000 μg/l), respectively, and lower than the standard (1300 μg/l) for copper in drinking water ofAhvaz. According to Lead and Copper Rule, since 10 percent of the samples have lead and zinc concentrations higher than USEPA standards, the drinking water of Ahvaz is considered corrosive, and the possibility of leakage of heavy metals such as lead and zinc into the city’s drinking water exists. The results of the study revealed that Lead and Copper Rule could be used easily for the determination of corrosion potential in drinking water distribution networks; therefore, with the application of this method, there is no need for the imprecise and complicated calculations of the existing routine methods.

  Corrosion and precipitation are the most important factors in the quality control of drinking water networks play an important role in the transmission system and distribution of water in transmission system and the distribution of water in terms of health and economic aspects can play.The aim of this study was to determine the potential for corrosion and perecipitation of drinking water used in Ghaemshahr villages, that was done in 2015. Physical and chemical quality samples and the potential for corrosion and precipitation were determined by Langlier, Rayzner, Puckorious, Aggressiveness, and Larsson. Results indicate that mean and standard variation for Langlier index is 0.052 and 0.43, for Rayzer index is 6.99 and 0.78 for aggressiveness index is 5.85 and 0.81 for Larsson indexrespectivity is 0.47 and 0.24. According to these finding it was concluded that drinking water of Ghaemshahr villages was mild precipitation. Manuscript profile
