Water Quality Index (WQI) is a single dimensional number that aggregates information from many water quality parameters according to a defined method. WQI is accepted as an efficient tool for water quality management. In this study, WQI of Saigon river for public water supply was calculated from nine water quality parameters including pH, suspended solids (SS), dissolved oxygen (DO), chemical oxygen demand (COD), nitrite, ammonia, phosphate, total dissolved iron and total coliform based on water quality data obtained monthly from January 2016 to December 2019 at three sampling sites.

The study was conducted to understand the ground water quality by using different irrigation water suitability indices in Guntur channel command area for drinking and irrigation purpose. Total twenty five ground water samples were collected during post and pre-monsoon season. Physicochemical parameters like pH, electrical conductivity, calcium, magnesium, carbonates, bicarbonates, sodium, total dissolved solids, total suspended solids were analysed using standard procedures. The values obtained were compared with the standards of BIS and WHO.

The performance of a vertical subsurface flow constructed wetland (VSSFCW) for sewage effluent treatment was studied in an eight month experiment under different operational conditions including: vegetation (the presence or absence of common reeds ‘‘Phragmites australis”), media type (gravel or vermiculite), and mode of sewage feeding (continuous or batch). Plants had a significant effect (P < 0.05) on the removal efficiency and mass removal rate of all pollutants, except phosphorous.
