"Based on a research, 84 percent of water in Cisadane River is polluted by domestic waste," Affandi Permana, the head of the Tangerang environmental affairs office, said here on Thursday.
The domestic waste polluting the river came from households, hotels, restaurants and vehicle workshops, he explained.
Industrial waste particularly coming from iron and manganese plants constituted 14 percent of the total pollutants in the river, and the remaining two percent was waste from other sources.
The Tangerang city administration has warned that it will close down a factory if it is proven to have polluted the city.
Of 100 plants existing in Tangerang city, 63 are obliged to set up good waste treatment facilities.
"If they violate the regulation, they will be given a sanction," he said.
Ahmad Marju Kodri, the director of clean water supplier PT Tirta Benteng of Tangerang, earlier said that the city`s water was polluted by iron and manganese elements.
"Every month, I send letters to the Tangerang environmental affair office and the Banten provincial administration about the industrial pollution," he said.
