Physico Chemical and microbial assessment of drinking water from different water sources of Tiruchirappalli District, South India

P. Pavendan, S. Anbu selvan and C. Sebastian rajasekaran

A study was undertaken to investigate the quality of drinking water samples in and around Tiruchirappalli district. Pollution of water bodies is one of the areas of major concern to environmentalists. Water quality is an index of health and well being of a society. Industrialization, urbanization, and modern agriculture practices have direct impact on the water resources. These factors influence the water resources quantitatively and qualitatively. Examination of the physico-chemical profiles of the bore well, open well and corporation water samples of Tiruchirappalli District, Tamil Nadu, India showed that the open wells were highly polluted with very high levels of total dissolved solids, total alkalinity and total hardness, and the bore wells with fluoride content higher than the permissible limit of the World Health Organisation. The deep aquifers had higher fluoride levels than the open well aquifers. Microbial pollution was recorded in 12.0% of bore wells, 11.1% of open wells and 6.3% of corporation water samples
