ANALYSIS ON THE GROUNDWATER QUALITY OF HPA-AN TOWN
Abstract
- This paper presents the water quality of tube-wells in Hpa-An Town located in the southern continuation of Eastern Highland. In the area, different water sources are found with high content of chemical parameters that are harmful for human health. Most of town dwellers consume shallow tube-well water. It is important to know the quality of tube-well water and thus samples of tube-wells water extracted in different parts of the town are studied. The objectives of this paper are to explore the spatial variation of water quality in the study area, to find out the relationship between selected water quality parameters and tube-well depth and to assess the impact of ground water quality on local people. The data on groundwater consumption and local people’s perception were collected through field observation, structured interviews and departments concerns. Inverse Distance Weighted (IDW) are used to analysis the parameter of pH, Salinity, Total Dissolved Solid, Turbidity, Total Hardness, Calcium, Magnesium, Chlorine, Iron and Salinity. To assess the correlation between spatial variation and water quality parameters (six pairs – Total Dissolved Solid and Electrical Conductivity, Salinity and Electrical Conductivity, Salinity and Total Dissolved Solid, Calcium and Total Hardness, Calcium and Magnesium, Total Hardness and Magnesium) Pearson’s Correlation Coefficient Method, Scatter Diagram Analysis (R2 ) is used. Hierarchical Cluster Analysis (SPSS, Ward Method) is used to identify the spatial variation of water quality of study area. The test results indicate that Turbidity, Iron and magnesium contents are higher than the acceptable level of WHO (2017) and Myanmar National Drinking Water Quality Standard (MNDWQS-2006). In addition, test results of pH value are lower than the permissible level of WHO and MNDWQ Standards. All groundwater samples are not suitable for drinking and cooking purposes.
