The GIS framework is used to assess Lucknow City's groundwater quality using the water quality index WQI

Monitoring groundwater quality continuously is essential to reducing the dangers of geochemical pollutants through suitable treatment techniques and guaranteeing safe drinking and irrigation. Thus, this study's main goal was to evaluate the appropriateness of the groundwater that was collected, from India's Lucknow for irrigation as well as drinking. To assess the quality of the groundwater in the research area, ten samples were taken from various locations. Analysis was done on some parameters, including pH, total dissolved solids (TDS), electrical conductivity (EC), total hardness, total alkalinity, BOD, COD, nitrate, total nitrogen, E. Coli, and ammonia. The water quality index (WQI) has arithmetical weights. Using a critical grading system that shows overall quality, the water's quality was evaluated and categorized as very good, good, moderate, bad, and unfit for consumption. Increasing public understanding and decision-making to make informed choices about efficient care, management, and long-term, sustainable social growth is greatly aided by this classification. To find relationships between the different parameter values, a correlation matrix was created and examined. As a result, the results imply that the groundwater in the investigated region is secure and appropriate for irrigation and consumption.
