The present study investigates the physico-chemical qualities and fecal contamination of ground water; and related health risks of rural areas of trans-Ganga and Yamuna region of a North-Indian district, Allahabad, India. The pH, turbidity, TDS, BOD, and COD, total alkalinity, total hardness, chloride and fecal coliform contamination was estimated in 269 water samples of 14 villages. Higher levels of turbidity, alkalinity, chloride and fecal contamination in ground water of trans-Yamuna area were found as compared to trans-Ganga. About 75% samples of trans-Yamuna were contaminated with faecal coliform as compared to trans-Ganga region (55%).Significant positive correlation existed between chloride, TDS, alkalinity (r=0.74- 0.91; p < 0.05), hardness and pH (r = 0.75-0.85; p < 0.05). The Relative Risk (RR) of some waterborne diseases was very high (2.11-8.00) in trans-Yamuna as compared to trans-Ganga region (1.81-3.48). Furthermore, the new treatment requirement parameter (NNT) for waterborne diseases of these rural areas was also estimated, which suggests that the need of a new and improved treatment approach for these diseases is more frequent in the trans-Yamuna area as compared to trans-Ganga. Our results suggest urgent attention and intervention for improving the quality of potable water in these rural areas and to control the waterborne diseases associated to rural health risks.
