An Evaluation of Physico-Chemical Properties to Asses Well Water Quality in Some Areas of Ernakulam District, Kerala, India

Five samples of home well water from various regions and one sample of water from Kerala Water Authority of Ernakulam district were collected and assessment of physico-chemical properties was made to see whether these water sources are satisfying the standards of drinking water. Parameters like pH, electrical conductivity, total dissolved solids, colour, odour, taste, turbidity, total hardness, total alkalinity, biochemical oxygen demand, dissolved oxygen, calcium, chlorides, magnesium, sulphates, iron and nitrates were analysed. The investigation reveals that with the exception of water sample collected from Kerala Water Authority, all the home well waters have water quality problems. Therefore, it indicates that all the samples of home well waters in the present study are undesirable or otherwise unfit for human consumption.
