QUALITY OF DRINKING WATER AND ITS IMPACT ON HUMAN BEING AT KHAGAUL CITY OF PATNA [BIHAR]

LIFE SCIENCE

The present study deals with comparative quality of drinking water from different sources at khagaul city of patna (Bihar). Which is located on the bank of Ganga river at 25 0 35’ N latitude and 85 0 03’ E longitude.It has an average elevation of 55 meters. Khagaul is a nagar parishad city of patna (bihar). Water is essential for survival of life; up to 60% of the human adult body weight is water. Intracellular fluid is about 35 liters (40% of body weight) and extracellular fluid is about 15 liters (24% of body weight). The palatability of drinking water has been rated by panels of tasters in relation to its TDS level, excellent if less than 300 mg/liter; good if between 300 and 600 mg/liter; fair if between 600 and 900 mg/liter; poor if between 900 and 1200 mg/liter; and unacceptable if greater than 1200 mg/liter.The municipal supply water gets severely contaminated by waste water through rusted and damaged pipelines and the ground water through seepage from septic tanks and drains. The contaminants from these sources have deteriorated the quality of drinking water leading to spread of various water born diseases like Typhoid, Cholera, Dysentery, Jaundice, Amoebiasis. The Ground water in the city is within required desirable Physio-chemical limits and hence potable.
