Abstract

Ground water is a significant source for drinking, agricultural and aquaculture purposes in Godavari region. Groundwater if contaminated due to manmade activities cause concern on environment and human health. The aim of the present study is to review the impact of aquaculture on environment briefly and to assess the ground water quality in East Godavari District. Aquaculture activities are major impact on water resources-they are physical, chemical and biological. Physically there is a lot of pressure on water; chemically it is polluted the water as well as land; biologically it introduces exotic species, pathogens and diseases. It is due to poor planning of land and water resources management. These aquaculture ponds require mixing of bore-well or creek waters with fresh water for daily change activities, due to this practice the polluted water is discharged into the channels from the upstream aquaculture ponds that same water is used by downstream aquaculture ponds; this is the main cause for increasing pollution in many folds aquatic environment. Over-exploitation of ground water and land use conversions to aqua-culture are becoming source of salt water intrusion. Pollution, destruction of sensitive coastal habitats, threats to aquatic bio-diversity and significant socio-economic costs must be balanced against the substantial benefits.
