Introduction: It is important to have safe and potable source of water supply for health benefits. Government public hand pump are now a days most common mode to access safe and potable ground water to the villagers for drinking and other domestic purposes.
Objectives: The aim of present study was to assess pre and post monsoon variations in selected physico-chemical properties of public hand pump water in a rural area of Barabanki district.
Material & Methods: A descriptive study was conducted among five randomly selected villages in Satrik block of Barabanki district, Uttar Pradesh. Water sample were collected twice (before and after monsoon) from most frequently used 23 public hand pumps in these villages. The pH was assessed using pH indicator strips and total hardness and chloride content was estimated using standard EDTA (Ethylene di-amine tetra-acetic acid) and AgNO3 (Silver Nitrate) titration method respectively. The total dissolved solid (TDS) was estimated using digital TDS meter.
Results: Proportion of public hand pumps with water specimen better in colour, transparency and odour tends to increase after monsoon. However no difference was observed in palatability of water. A significant increase was observed in mean level of chloride content (from 125.04 ± 4.06 mg/L to 120.30-133.9 mg/L), TDS levels (from 275.86 ± 11.63 mg/L to 277.56 ± 11.61 mg/L) and hardness of water (from 111.60 ± 5.96 mg CaCO3 /L to 120.40 ± 5.57 mg CaCO3 /L) in pre and post monsoon water samples.

Conclusion: Groundwater accessed through public hand pumps were found quite safe for drinking and domestic purpose in basic physical parameters, TDS, hardness and chloride content both before and after the monsoon period.
