Abstract
    A field study has been made of the quality of water in three estuaries in Madras, India, receiving a variety of human and industrial wastes. Among the three estuaries, the Buckingham canal is grossly polluted with no surface flow. The Cooum estuary, though grossly polluted, because of the flow and flushing into the sea may be recovered if precautions are taken. The Ennore estuary, with a large volume of water flowing, has a peculiar problem at the mouth due to continuous formation of a sand bar due to long-shore currents. This sand bar prevents the flushing of the estuarine water. As a result, the pollutants discharged either in the estuary or in the sea accumulated at the mouth. This pollution, together with impaired self-purification of the estuary, resulted in a decrease in fish production.
