Abstract
This study was focused on the variation of physico-chemical parameters in water samples taken from Vattakkayal, a part of Ashtamudi estuary-Ramsar site in Kerala. Water samples from 5 sampling sites in the Lake were analysed for various water quality parameters during the year February 2013- January 2014. The measured water quality parameters were compared with the guidelines proposed by the WHO for drinking water and natural background levels. The results showed that the values of major water quality parameters were higher than the maximum permissible limit of natural background concentrations and recommended values by WHO. The major water pollution threats in the lake were identified as urban and agricultural land uses. This study is believed to assist decision makers in identifying priorities to improve water quality that has deteriorated due to various land uses.
