摘要:In the present study, physico-chemical and microbiological characteristics of different sources of surfaceand groundwaters in Tripunithura, a suburb of Ernakulam district, Kerala were determined during February2011. The objective of the study was to asses the suitability of water for human consumption and otherdomestic purposes. Water samples from three different densely populated localities were collected andanalysed for various parameters using standard methods. The physico-chemical parameters of home wellwater and pond water, with the exception of iron value in pond water, were satisfactory whereas bore wellwater and river water exhibited all the values as exceeding maximum permissible limit with a few exceptionsof sulphate and dissolved oxygen in bore well water and nitrate in river water. The microbiological analysisrevealed that with the exception of bore well water, all other waters fail to satisfy the prescribed standards setfor drinking water. Therefore, the study revealed that the entire water samples investigated in the presentstudy failed to qualify the prescribed standards for drinking water either in the physico-chemical aspects orin the microbiological aspects or both.
