Groundwater is an important entity of our hydrological system. The present study focus on the drinking water quality status of selected dug wells of a coastal area in Kerala, India for pre monsoon and monsoon season. Of the samples collected, about 80% of the water samples are contaminated with Escherichia coli in pre monsoon and 100% percentage in monsoon. Iron concentrations in 65% of the water samples were found to be higher than the drinking water standards of Bureau of Indian Standards (BIS). The present study concludes that even though water comes in “good water” index, the well water is unsuitable for drinking due to its high iron and coliform contamination.
