Jakarta: Eight rivers in Gorontalo polluted with hazardous substances

Eight rivers located in regencies and municipalities across Gorontalo province have been polluted with hazardous inorganic chemical substances. Some of them are so heavily polluted their water is undrinkable.

The head of Gorontalo administration’s Information Technology, Research and Environment Agency, Nontje Lakadjo, said the eight rivers polluted with dangerous chemicals comprised the Andagile Atinggola, Biyonga, Bolango, Bone, Buladu, Paguyaman, Randangan and Taluduyunu rivers.

“Three out of eight rivers, namely Bone, Paguyaman, and Randangan, are the main river basin areas that Gorontalo residents depend on for their water resources,” said Nontje........
Several points in the Bone’s upper, central and lower course measured moderate levels of pollution in which the water pollutant parameters had not yet exceeded the maximum levels considered safe. Mercury levels at sites on the Bone were detected at 0.001 milligram per liter while the maximum permissible level is 0.002 milligram per liter. Meanwhile, the cyanide level found in the Bone was 0.01 milligram per liter.
