Project
Riau has potential hazards and disaster mitigations that need to be concerned, so hopefully from this project will create some idea to resolve problems in this province.
Project
Mapping of groundwater aquifer in Pekanbaru areas to define the source of clean water. Mapping will be conducted by measuring the water well in the areas and will be supported by geoelectrical data. The water then be assessed to some drinking water quality standard whether it is suitable for daily consumption or not.
