Abstract: The Geological Survey in Peninsular Malaysia has been involved in groundwater investigations since its inception in 1903. ln 1953 investigations under the Perlis Water Supply Scheme resulted in the exploitation of groundwater in Arau. Between 1955-1958 the Department, in collaboration with UNTAA (United Nations Technical Aid Assistance) implemented a regional hydrogeological investigation of the coastal areas of Peninsular Malaysia which resulted in the location of several potential water bearing zones.
During the Third Malaysia Plan (1976-1980) the Department together with the German Hydrogeological Mission successfully completed a programme of investigation in Kelantan, Terengganu, Pahang, Kedah and Perlis. Under the Fourth Malaysia Plan (1981-1985) the Geological Survey embarked on a hydrogeological investigation in Seri Gading, Johor and the Rembau-Tampin-Gemas area, Negeri Sembilan/Melaka.
ln Sarawak prior to 1970 the Public Works Department undertook hydrogeological investigation and exploitation in the state. However, since 1975 the Geological Survey has been conducting hydrogeological investigations along the coastal plain. To-date 15 areas have been studied and fresh groundwater has been located in 9 of these areas.
A hydrogeological map of Peninsular Malaysia on a scale of 1:500,000 was published in 1975. The hydrogeological map of Sarawak on the same scale has been compiled and will be published in 1985.
