The present study analyses the spatial variations of groundwater qualities in the Mogamureru basin of the Vempalle Mandal, YSR district of Andhra Pradesh, South India. Twenty-two groundwater samples from the post-monsoon season collected in January 2020 and tested in the laboratory for chemical analysis including Carbonate (CO3-), Bicarbonate (HCO3-), Magnesium (Mg2+), Chloride (Cl-), Calcium (Ca2+), Sodium (Na+) and Potassium (K+). The spatial variations in quality parameters mapped using interpolation technique in ArcGIS software. Water Quality Index (WQI) calculated for quality analysis and four groundwater samples classified into very poor category and eighteen samples are unsuitable for drinking purpose. The usage of groundwater for drinking purpose needs a proper water quality treatment for better health implications. The methodology adopted in this study has been found to be effective and can be used to establish strong water quality monitoring network in similar areas.

The study focused on analyses of water quality index (WQI) for semi-arid regions of Kadapa, Andhra Pradesh, India.

The acquired water quality index was compered with the BIS and WHO standards.

Four groundwater samples classified into very poor category and eighteen samples are unsuitable for drinking purpose.

The groundwater needs a proper water quality treatment for better human health in the region.
