ABSTRACT
Groundwater by the domestic wells has been used in Kuchchaveli area of Trincomalee district for the use of domestic purpose, home gardening and cultivation. The demand for the ground water has been increased rapidly due to intensive high population growth and more industrialization. The main purpose of this study is to identify the seasonal changes of groundwater quantity and quality from the domestic wells. The study was carried out by using primary and secondary data. Primary data has been gathered through the sampling of 50 users and the water level changes for 50 domestic wells from 24 GN divisions. Meteorological and irrigation department’s repots, images were utilized for this study, published reports and statistical records were employed to collect as secondary data. In addition, rainfall data of 143 years from the meteorological department was used for the analysis. MS Excel, SPSS, GIS software were used for data analysis. The water level was observed during the dry and rainy seasons, the ground water level in this area decreases due to over use of ground water. Run-off has increased due to low infiltration, which leads to low ground water storage. The following recommendations could be made from the results of study. Rainfall water should be saved for future use. Optimum use of rainfall, the re-use of irrigated water and avoiding the construction of deep wells help to prevent salinity.
