Pollution Burden Analysis And Assimilation Capacity Of Cidurian River Banten Province

Abstract

The river has the ability to clean itself of the burden of pollution naturally which is known as the capacity of assimilation. Incoming load exceeds the capacity of assimilation would lead to a decrease in the quality of the river until the river functions decline. This research aims to analyze the water quality of Cidurian River, analyze the contribution of pollution loads entering River Cidurian, and knowing the assimilation capacity of the stream. Research results show that the water quality, starting from the upstream to downstream concentrations of BOD, TSS, COD and E. coli are likely to exceed the standard of quality. Contribution to the total burden of polluters from certain sources (point source) in DAS Cidurian 2,4 tons/month BOD, COD 4,3 tons/month, TSS 2,26 tons/month. The contribution burden of polluters undefinable (non point source) based on the analysis of land use from agricultural sector BOD 206,76 tons/month,TSS 24,13 ton/month, based on the analysis of the population of each sub DAS, domestic sector have 1.374 tons/month of BOD, COD 1.890 tons/month, TSS 1.305 tons/month and E.coli 1,02 E 16 tons/month. Total contribution burden of polluters undefinable (non point source) parameters BOD 1.580 tons/month, COD 1.890 tons/month, TSS 1.324 tons/month, more dominant compared to certain sourced (point source). Capacity of assimilation to the parameters of TSS 22.901,55 tons/month, BOD 2.347,83 tons/month, COD 24.208,33 tons/month, E.coli 424.629,90 tons/month. Overall value of assimilation capacity is smaller compared to the burden of pollution of the river, resulting in the organic matter pollution experienced TSS, BOD, COD and E.coli. The high contribution to the burden of domestic source of polluters and agriculture, as well as the capacity of assimilation to consider in an attempt to control water pollution.
