4-Seasonal Variation of Groundwater Quality along Coastal Areas of Kozhikode District.

Abstract

Population density in the coastal belt of Kerala and the agricultural and industrial growths in these areas have resulted unusual stress on the drinking water availability and its quality. In the light of above. field investigations on the groundwater quality along Kozhikode coast has been investigated. To study the behaviour of ground water quality of open wells along the various coastal stretches of Kozhikode District, CWRDM has set up few observation network of open wells along the coast. The results of water quality of these wells in premonsoon, monsoon, and postmonsoon seasons have been analysed and presented in this paper. Field observations indicate that depending on location within the coastal belt, every centimeter drop of ground water table is met with an increase of 1 to 20 ppm total dissolved solids and increase of 0.5 to 8 ppm of Chloride. Study also reveals that seawater has an effect upon 900 metres from the shore.
