Evaluation of hydrochemical properties and groundwater suitability for irrigation uses in southwestern zones of Jashore, Bangladesh

The evaluation of hydrogeochemistry and groundwater quality for irrigation purposes has become a major concern for the inhabitants of southern part of Bangladesh. In this present study, the suitability of irrigation system has been shown by the spatial distribution maps using irrigation water quality index (IWQI). One hundred groundwater samples were collected to evaluate groundwater quality for irrigation system using IWQI, and atomic absorption spectrophotometer, ultraviolet spectrophotometer and titration methods were used for identification of groundwater quality using various parameters. ArcMap 10.5 (GIS), geospatial analysis tools (SSPS), descriptive statistics, correlation matrix and interruption methods were applied owe to produce the maps of geospatial distribution, and measurement of suitable area for irrigation. The hydrochemical parameters of pH, EC, TDS, Na, K,…
