POLLUTION LOAD CAPACITY STUDY ON BARITO RIVER, SOUTH KALIMANTAN, INDONESIAT. ZUBAIDAH, N. KARNANINGROEM, A. SLAMET, M. RATODI AND LENIE MARLINAEAbstract Due to the domestic waste, mining, plantation, agriculture and industrial disposal, Barito river has experienced a very serious water contamination. Therefore the researchers intended to investigate Barito rivers ability in accommodating the pollution load in order to improve the river quality. In this article, the Biochemical Oxygen Demand (BOD) parameter has been selected as an index that reflected the organic contamination, while the QUAL2Kw stream model was used in conjunction with a potential pollutants identification and inventory activities as an effort to calculate the Barito rivers ability to contain pollution loads. The results have shown that the Barito river has no longer the assimilation capacity for BOD. We have determined that the distribution of pollutant loadsand total quantity controls has been able to help the Barito river water utilization to be more efficient.
