Water quality indices (WQIs) have been developed to assess the suitability of water for a variety of uses. These indices reflect the status of water quality in lakes, streams, rivers, and reservoirs. The concept of WQIs is based on a comparison of the concentration of contaminants with the respective environmental standards. The number, frequency, and magnitude by which the environmental standa...

BACKGROUND Using treated wastewater in agriculture irrigation could be a realistic solution for the shortage of fresh water in Iran, however, it is associated with environmental and health threats; therefore, effluent quality assessment is quite necessary before use. The present study aimed to evaluate the physicochemical and microbial quality of Shiraz wastewater treatment plant effluent for b...

The water quality of a basin is pronouncedly affected by the surrounding types land use. Analyzing impact LULC and landscape patterns on critical for identifying potential drivers. To further study how LUCC affects in typical plateau lake basin, this investigated impacts land-use Dianchi Lake Basin Southwest China. We analyzed changes pattern calculated CWQI (Canadian Water Quality Index) value...
