Hydro-Chemical Classification and Microbiological Analysis of Groundwater in parts of Western Delta, West Godavari District, A.P, India.

ABSTRACT Godavari river is the third largest river in India. The Godavari river flows in five different states and enters into state of Andhra Pradesh and then to Bay of Bengal. Most of the people in this Godavari delta region depends on agriculture and West Godavari district stood in state first place in paddy production. The water flows are shared among the six states of the Godavari basin. In recent years, due to declining nature of rainfall and surface water flow, farmers are forced depend on groundwater for their agriculture, drinking and basic needs. The overexploitation of groundwater leads to depletion of shallow aquifer and it is big threat to water crisis. In the present study groundwater quality was carried out in Kakaraparru-Bank canal region. About 27 groundwater samples were collected from 13 different villages from the study area to compare the seasonal variations and to monitor the water chemistry of physico-chemical and microbiological studies in summer and rainy seasons. The results were compared with WHO and BIS standards. Keywords: Drinking water quality, Groundwater, Microbiological analysis, Seasonal variation, Brackish water.
