the river is heavily polluted by human activity; about five million people live in its basin. textile factories in bandung and cimahi were major toxic waste contributors. more than 2,000 industries contaminate 5,020 sq miles of the river with lead, mercury, arsenic, and other toxins. according to the documentary "green warriors indonesia" by martin boudot, some of the other toxins include sulphites, nonylphenol, phtalates, pcb 180, paranitrophenol, tributylphosphate. the documentary also mentions that the most dangerous pollution comes from the indonesian textile industry (with many textile factories being part of asosiasi pertekstilan indonesia). it is also mentioned that the textile factory effluents are only tested on a very select number of parameters. it was thus also proposed in the documentary that a revisal on the textile industry guidelines could include more parameters such as sulphites and heavy metals.
