Assessment of well-water quality for drinking purpose--a case study in Nari area, Nagpur District, Maharashtra (India).

The water from 20 wells of Nari area was assessed for different quality parameters. The nitrate (NO(-)3) concentration ranged from 57 to 80 ppm which is above the BIS limit while nitrite (NO(-02) concentration was within the BIS limit of 0.02 ppm. The pH of the water samples varied from 7.3 to 8.2. The concentrations of micronutrient cations, namely Zn, Fe, Cu and Mn, were below the toxic level in all the samples but some of the samples of the water had high and infinite growth of E. coli, Coliform bacteria, Pseudomonas aerugilosa, Yeast and molds count makes the well water of poor quality for drinking purpose.
