The Department of Environment and Forestry (DLHK) of Central Java highlighted that there was still a lot of industrial waste being dumped in the Bengawan Solo River. This is a source of problems that often occur every year, especially during the dry season.
"Large industry and small industry have been a source of pollution problems in the Bengawan Solo River," said the Acting Head of DLHK of Central Java Province, Widi Hartanto.
He said that the pollution of the Bengawan River was also exacerbated by the large amount of household waste from surrounding settlements. Although the content of pollutant levels is not as severe as industrial waste or alcohol, household waste also needs to be a common concern.
“The most pollution of the Bengawan River in Central Java comes from the textile industry. If you look at the hazardous substances, the alcohol industry is more dangerous," he said.
Household waste, he continued, is also a problem that needs to be solved. The high content of harmful substances in the Bengawan Solo River is most pronounced in the dry season like today.
"In the rainy season the water discharge is high, making the waste directly carried away by the swift water of the Bengawan Solo River," he said.
However, during the dry season like now, industrial waste cannot be carried by the river because the water flow of the Bengawan Solo River recedes. Waste pollution also occurs in the tributaries of the Bengawan Solo River.
"We invite people who live in the Bengawan Solo River to take care of the river. If there is a violation of throwing waste into the river, immediately report it," he said.
