Spatial Assessment of Water and Sediment Quality in Burullus Lake Using GIS Technique

The Egyptian northern Deltaic lakes including Burullus Lake suffer from pollution of intensive agri culture, domestic and industrial activities. The objective of this research was to evaluate water and sediment quality in Burullus Lake based on certain physical and chemical characteristics. Mapping the spatial distribution of these parameters will be done using ordinary Kriging method to reveal the link with potential pollution sources. Geo-referenced water and sediments samples were collected from 34 and 37 representative sites in the lake, respectively. The obtained results indicated that the quality of both water and sediments in receiving drainage water of the southern parts of the lake were relatively inferior compared to that of the northern parts. So we recommended that wastewater from different drains should be treated before being drained into the Lake.
