This study was conducted in the department of Biology, College of Education, Mosul University. Purslane (Portulaca oleracea) was taken from six different farms distributed in the left bank of Nineveh province. These sites are Al-Sherikan, Eden, Vally of Al-Shur, Al-Atebba’a, Gerif Al-meleh, and Al- Furqan The Plants in these sites were irrigated by different sources of water like artisan wells, domestic, or domestic and industrial wastes water. The results revealed that there was a significant decrease in the growth of Purslane in the farms of Edan and Vally of Al -Shur Which were irrigated by the domestic and industrial waste water. It was observed that there was a significant decrease in the length of Shoot group and dry weight of Shoot and root group and the concentration of chlorophyll a, the total chlorophyll, water content and cell membrane stability. Also, there was a significant increase in potassium and sodium filtrations in the leaf tissues. Moreover, there was a significant decrease in the concentration of carbohydrate and protein in Shoot group where as there existed significant domination of the growth of Purslane in the Al, Sherikan farms which were irrigated by the wall water in comparison with other areas.
