Physico-chemical quality of surface water within Long Banga upper Heart of Borneo Island catchments

Assessment of physico-chemical water quality of Long Banga upper catchment in Heart of Borneo area, Sarawak, Malaysia was conducted during Scientific Expedition 2016. The purpose was to ascertain the water quality level within these highland catchments. The results were compared with Malaysia Interi...
