Well water samples were collected from Dass, Kaltungo and Langtang North Local Government Areas and drinking water quality parameters such as temperature, pH, conductivity, chlorides, total hardness, phosphates, sulphates, nitrates, turbidity, total dissolved solids (TDS), alkalinity and fluorides were determined using standard techniques. The results showed the mean and standard deviation values of temperature ranged between 27.80 ± 0.45 to 28.80 ± 0.48ºC, pH; 7.74 ± 0.13 to 7.80, conductivity; 30.20± 0.56µs/cm to 38.80±0.40µs/cm, turbidity; 3.60±3.50 to 13.50± 1.09 NTU, TDS; 166.40± 5.50 to 184.08± 1.47mg/L, Alkalinity; 78.40± 1.10 to 150.40±2.30mg/L, Total Hardness; 137.8±11.20 to 336.8±15.2mg/L, Sulphate; 8.04±0.09 to 24.00±0.84mg/L, Phosphate; 0.14±0.02 to 0.86±0.55mg/L, Nitrate; 9.78±0.84 to 24.42±0.15mg/L, Fluoride; 1.72±0.11 to 2.08±0.11mg/L, Chloride; 18.40±3.21 to 82.10± 6.52mg/L. All the parameters analysed are within the specification levels for drinking water, except turbidity, nitrates and fluorides which gave higher values. The well water samples may be good for consumption but will require purification and fluoride treatment to avert the problems of stained and mottled teeth experienced by the local consumers in those areas.
