Studies were conducted to investigate the status of water bodies and their effect on human health in district Badin Lower Sindh, adjoining the Arabian Sea coast, with very saline underground water. Water samples were collected from representative water bodies. In all, 99 water samples were obtained and analyzed five from water courses, 68 from hand/motor pumps, 10 from dug wells, 03 from ponds and 13 from water supply schemes. The samples were analyzed for pH, electrical conductivity (EC), dissolved oxygen (DO), total suspended solids (TSS), total coliform count, turbidity, alkalinity, hardness, phosphorus, copper, manganese, iron, zinc and sodium. It was found that 80% samples were contaminated with coliform bacteria, 26% samples had high TDS, 62% with higher alkalinity, 31% showed higher Na and iron concentration, 24% had higher hardness and 19% samples with higher pH values. Phosphate, Mn, Cu and Zn concentrations were however within allowed range under standard permissible limits. The study draws the attention of all the agencies responsible for providing clean potable water for domestic use to the rural masses, to take appropriate measures in this regard. Relevant recommendations and suggestions are given to redress the grievances of the people of the area who have no other option except using the canal and seepage water for domestic purposes.
