Life cycle assessment (LCA) is a method to analyze a particular product or service; from the beginning of the process it is extracted until it is no more in use or much to be known as 'cradle to grave analysis'. The LCA analysis includes collection of inventory that is all types of emissions and also waste products. After that, this inventory would be translated or transformed to show the impact on environment in the life cycle impact assessment (LCIA). Two LCIA methods has been accepted such as midpoint and endpoint approach. The EDIP 97 is a LCIA method which uses midpoint approach. From the analysis done on the two stages, life cycle assessment for potable water production that is construction stage and production stage; it is found that production stage contributes the highest impact on acidification and euthrophication which is derived from the PAC production process. Whereas, the construction stage contributes two main impacts which are human toxicity (water) and chronic water ecotoxicity which are produced through the process of steel production. © 2011 Academic Journals.
