Peninsular Malaysia • Groundwater development in Peninsular Malaysia started since the early 1900’s in Kelantan. 60% of the groundwater exploited is for domestic supply 35% for industrial supply and 5% for agricultural use. • To date about 0.2 Peninsular Malaysia. million m 3 /d of groundwater is being exploited in • In Peninsular Malaysia, 4categories of potential groundwater resources: The most productive aquifers are the alluvium (sand and gravel), which can yield from fom50 to 100 m 3 /h/well. The most productive aquifer in hard rock is in limestone, which can produce up to 50 m 3 /h/well. But most within the developed areas and extraction may develop sinkhole. Fractured sandstone, their metamorphic equivalent and aquifers can yield up to 30 m 3 /h/well. volcanic rock The least productive type of aquifer is made up of fractured igneous rocks, which can give 20 m 3 /h/well.
