| Abstract | The Centre for Environmental Studies of the Anna University, Madras, India, undertook a study in Tamil Nadu, India, to determine the changes in quality in drinking water from the source to the consumer. Water samples were taken from forty locations, covering surface water source, subsidiary sources including private and public wells and public stand posts. The study ran for 30 months, and 17 water quality parameters were analyzed. The raw water quality was poor, but the treatment facilities were good, and the water in the beginning of the distribution system was of high quality. Farther down the distribution line, the water quality proportionately deteriorated. Recommendations were made for chlorination at intermediate points, better preventive maintenance, and stabilization of pressure in the mains to prevent backsiphonage. |
