Ingress of Bhavnagar City (India).

A preliminary survey of the coastal city-Bhavnagar was undertaken to assess salinity ingress probed through groundwater quality. Water samples from the wells and bores located in the study area were collected and analyzed. Bhavnagar City is found significantly affected by the seawater intrusion. The ground water showed very high values of SO4(-2), Cl(-1), PO4(-3) and, Na(+1), K(+1) compared to the permissible limits for drinking purposes. The quality of ground water in some of the areas was found highly saline and can not be used even for irrigation purpose. The results also indicated a gradual encroachment of seawater into the native ground water.
