- Abstract
This study aimed to assess the quality of groundwater for drinking and irrigation in the Pandameru River basin, Andhra Pradesh, India. Groundwater samples were collected from 46 locations within the research region during the pre-monsoon season. These samples were analyzed for various parameters such as pH, EC, TDS, Ca2+, Mg2+, Na+, K+, HCO3−, Cl−, SO42−, and NO3−. The results were compared with WHO guidelines, indicating slightly alkaline groundwater. Analysis using the WQI and GIS-based interpolation provided an overall evaluation of water quality. WQI values range from 78.49 to 115.92 mg/L, indicating that 77% of the samples are safe for drinking, while 23% were unfit. Groundwater samples are found in the field of rock dominance, based on the Gibbs plot. The majority of the samples fell into the C3S1 category, which denotes water with high salinity and low sodium which is moderately suitable for irrigation purposes, according to the USSL diagram. Regarding cultivation, 78% were good, 20% doubtful, and 2% unsuitable based on the Wilcox classification. Except for a few locations, most samples were suitable for irrigation. However, some samples exceeded allowable contaminant levels due to human activity, requiring treatment before consumption.
