Groundwater resources in Johor, Malaysia: resource potential and information management

Abstract

Based on data from the exploration and development work of groundwater undertaken in Johore, Malaysia, the potential of groundwater resources in most rock types in the state can be evaluated. Variations of well-yield depend on the lithology, thickness and fracture intensity of the aquifers. The water quality also varies with aquifer materials and proximity to the sea. Raw data including borehole locations, aquifer properties and results of water analysis are compiled in hardcopy forms. However, with these data, including spatially-related data, there is a restriction to some extent on data presentation. With the Geographical Information System (GIS) approach, these data can be easily accessed for retrieval, query and presentation of information. This system is to be customised to enable users to search for any information related to groundwater.
