The Krishna and Godavari (East and West) districts of Andhra Pradesh, They have a flourishing agriculture and the farmers of these districts effectively use the mineral rich alluvium of the Krishna and Godavari deltas. The farmers extensively pump groundwater for irrigation and industries, resulting in excessive drawdown of freshwater. Also, saltwater intrusion is occurring along coast of these deltas due to over pumping. The nutrients generated by using fertilizers in agriculture are leaching subsurface as well as are discharging to the coast of Bay of Bengal. The project work is aimed at assessing the water quality index (WQI) for the groundwater in and around Gudlavalleru Mandal. This will be determined by collecting groundwater samples and subjecting the samples to a comprehensive physicochemical analysis. The results of analyses will be used to predict various treatment models before consumption of water.
