Studying Iranian Drinking Water Quality Guidelines Compared to the Authentic World Standards

Referring the World health Organization definition, a safe drinking water should not threat the consumer health over the lifetime of consumption. The objective of the present study is to investigate the present guidelines in order to improve the Iran drinking water guidelines. To obtain this, the present drinking water guidelines in Iran (named 1053 and 1011 standards) and some well-known guideline (WHO,US EPA and the European Communities) were studied. The Iran guidelines were compared to the other ones and the different points and values were presented as Tables. It was understood that the present drinking water guidelines of Iran do not cover areas such as the water quality indicators based on their resources and lack some suggestions about in-network monitoring plans. It is recommended that Iran guidelines should be revised in two categories: 1. The primary standard including the pollutants threatening the consumers health and the Secondary standards which should be prepared by the local water authorities.
